JAVA 项目---学生成绩管理系统（附标准源码）使用文件存储

项目要求，GUI界面，实现以下功能，能够录入学生的信息及成绩，具体为姓名、学号、应用数学、大学英语、java编程、计算机应用。还能够根据输入学生姓名返回学生的信息。

使用mysql数据库存储 参考这一篇博文：https://blog.csdn.net/qq_44973159/article/details/104119710
一、设置主界面
需要注意的是，在该程序时使用文件对数据进行保存，未连接数据库，记得根据自己电脑本身情况对路劲进行更改，以下代码都是保存在f盘下

我们首先需要简单注册，并且将注册的账号密码写入到文件当中，在登录的时候对账号密码进行判断，

	//主界面  登录界面，程序从此开始
	public class MyFrame01 extends JFrame {
	private JButton btn1;
	private JButton btn2;
	private JTextField tf;
	private JPasswordField pf;

	public static void main(String[] args) {
		MyFrame01 my = new MyFrame01();
	}

	public void init() {
		setTitle("学生登记系统");
		setSize(300, 180);
		setLocationRelativeTo(null);
		tf = new JTextField(5);
		pf = new JPasswordField(5);
	}

	public void add1() {
		btn1 = new JButton("登陆");
		JLabel name = new JLabel("       账号");
		JLabel password = new JLabel("       密码");
		JLabel bq1 = new JLabel("  ");
		JLabel bq2 = new JLabel("  ");

		JPanel p = new JPanel();
		JPanel p1 = new JPanel();
		JPanel p2 = new JPanel();
		JPanel p3 = new JPanel();
		JPanel p4 = new JPanel();
		JPanel p5 = new JPanel();

		btn1.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent e) {
				try {
					pd();
				} catch (IOException e1) {
					e1.printStackTrace();
				}
			}
		});
		btn2 = new JButton("注册");
		btn2.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent e) {
				new MyFrame03();//使用注册的时候要跳转到第三个界面，
				MyFrame01.this.dispose();
			}
		});
		this.setContentPane(p); // 设置为内容面板 总布
		p.setLayout(new BorderLayout());
		p1.setLayout(new FlowLayout());
		p2.setLayout(new GridLayout(2, 2));
		p3.setLayout(new FlowLayout());

		p1.add(new JLabel("登陆系统"));
		p2.add(name);
		p2.add(tf);
		p2.add(password);
		p2.add(pf);
		p3.add(btn1);
		p3.add(btn2);
		p4.add(bq1);
		p5.add(bq2);

		p.add(p1, BorderLayout.NORTH);
		p.add(p2, BorderLayout.CENTER);
		p.add(p3, BorderLayout.SOUTH);
		p.add(p4, BorderLayout.EAST);

	}

	public MyFrame01() {
		JPanel cp = (JPanel) getContentPane();
		cp.setLayout(new FlowLayout());

		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		init();
		add1();
		setVisible(true);
	}

	public void pd() throws IOException {
		File f = new File("F:\\信息系统账号");
		String fname[] = f.list();
		String a = null;
		for (String s : fname) {
			if (s.equals(tf.getText() + ".txt")) {
				a = s;
				Reader r = new FileReader("f:\\信息系统账号\\" + s);
				String b = null;
				char cs[] = new char[10];
				int len = 0;
				while ((len = r.read(cs)) != -1) {
					b = new String(cs, 0, len);
				}
				if (pf.getText().equals(b)) {
					JOptionPane.showConfirmDialog(MyFrame01.this, "输入正确！", "系统提示", JOptionPane.OK_CANCEL_OPTION,
							JOptionPane.CANCEL_OPTION);
					new MyFrame04();
					MyFrame01.this.dispose();
				} else {
					JOptionPane.showConfirmDialog(MyFrame01.this, "输入有误,请重新输入！", "系统提示", JOptionPane.OK_CANCEL_OPTION,
							JOptionPane.CANCEL_OPTION);
					MyFrame01.this.dispose();
					new MyFrame01();
				}
			}
		}
	}
}

二、登录成功后的功能页面

	//登录成功后的界面
	public class MyFrame04 extends JFrame {
	private JButton btn1;
	private JButton btn2;
	private JButton btn3; 
	private JButton btn4;

	public void init() {
		setLayout(new FlowLayout());
		setTitle("选择");
		setSize(275, 405);
		setLocationRelativeTo(null);
	}

	public void add() {
		btn1 = new JButton("录入学生信息");
		btn1.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent e) {
				new MyFrame02();
				MyFrame04.this.dispose();
			}
		});
		btn2 = new JButton("查找学生信息");
		btn2.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent e) {
				new MyFrame06();
				MyFrame04.this.dispose();
			}
		});		
		btn3=new JButton("查询成绩信息");
		btn3.addActionListener(new ActionListener() {
		public void actionPerformed(ActionEvent e) {
		 new MyFrame08();
		 MyFrame04.this.dispose();
		}
		});
		btn4 = new JButton("退出信息系统");
		btn4.addActionListener(new ActionListener() {
			@Override
			public void actionPerformed(ActionEvent e) {
				int x = JOptionPane.showConfirmDialog(MyFrame04.this, "是否退出系统？", "系统提示", JOptionPane.OK_CANCEL_OPTION,
						JOptionPane.CANCEL_OPTION);
				if (x == JOptionPane.OK_OPTION) {
					System.exit(0);
				}
			}
		});
		add(btn1);
		add(btn2);
// add(btn3);
		add(btn3);
		add(btn4);
	}
	public JPanel getFilePanel() {
		JPanel p = new JPanel();
		p.setLayout(new FlowLayout());
		p.add(new JLabel("选择你要进行的操作！"));
		return p;
	}
	public MyFrame04() {
		JPanel cp = (JPanel) getContentPane();
		cp.setLayout(new FlowLayout());
		cp.add(getFilePanel());
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		init();
		add();
		setVisible(true);
	}
}

三。录入学生信息 ：录入后的信息将保存在f盘下的学生信息文件夹下，以学生名命名的txt文本文档

	//信息录入,把学生基本信息录到进来，保存在f盘下学生信息中，  
public class MyFrame02 extends JFrame { 
private String xh; 
private String yysx; 
private String dxyy; 
private String java; 
private String jsjyy; 

private JMenuBar bar; 
private static JTextField tf1; 
private static JTextField tf2; 
private static JTextField tf3; 
private static JTextField tf4; 
private static JTextField tf5; 
private static JTextField tf6; 
private static JButton btn1; 
private static JButton btn2; 
public void init() {
	setLayout(new FlowLayout());
    setTitle("学生信息录入");
    setSize(500, 300);
    setLocationRelativeTo(null);
}
public void add(){
    bar=new JMenuBar();
}
public MyFrame02() {
	 JPanel p=new JPanel();
	  JPanel p1=new JPanel();
	  JPanel p2=new JPanel();
	  JPanel p3=new JPanel();
	     p.setLayout(new BorderLayout());

	     p1.setLayout(new GridLayout(4,2));
	     p2.setLayout(new FlowLayout());
	     
	     p1.add(new JLabel("姓名"));
	     tf1=new JTextField(10);
	     p1.add(tf1);
	     p1.add(new JLabel("学号"));
	     tf2=new JTextField(10);
	     p1.add(tf2);
	     p1.add(new JLabel("应用数学"));
	     tf3=new JTextField(10);
	     p1.add(tf3);
	     p1.add(new JLabel("大学英语"));
	     tf4=new JTextField(10);
	     p1.add(tf4);
	     p1.add(new JLabel("java编程")); 
	     tf5=new JTextField(10);
	     p1.add(tf5);
	     p1.add(new JLabel("计算机应用"));
	     tf6=new JTextField(10);
	     p1.add(tf6);
	     p1.add(new JLabel());//再加上一个标签把整个代码布局撑起来
	    btn1=new JButton("保存");
	    btn2=new JButton("取消");
	     p2.add(btn1);
	     p2.add(btn2);

	     this.setContentPane(p);
	     p.add(p1,BorderLayout.CENTER);
	     p.add(p2,BorderLayout.SOUTH);

	  setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	  init();
	  add();
	  setVisible(true);

	  btn1.addActionListener(new ActionListener() {
	        public void actionPerformed(ActionEvent e) {
	            int x=JOptionPane.showConfirmDialog(MyFrame02.this, "是否保存？", "系统提示", JOptionPane.OK_CANCEL_OPTION,JOptionPane.CANCEL_OPTION);
	            if (x==JOptionPane.OK_OPTION) {
	                try {
	                      cj();
	                    test01();//test01 静态方法，将数据写入的文件中（文本文档）
	                    JOptionPane.showConfirmDialog(MyFrame02.this, "保存成功", "系统提示", JOptionPane.OK_CANCEL_OPTION,JOptionPane.CANCEL_OPTION);
	                MyFrame02.this.dispose(); 
	                new MyFrame02();//再一次回到该界面(录入信息界面)
	                } catch (IOException e1) {	                   
	                    e1.printStackTrace();
	                }
	        }else{
	                JOptionPane.showConfirmDialog(MyFrame02.this, "保存失败", "系统提示", JOptionPane.OK_CANCEL_OPTION,JOptionPane.CANCEL_OPTION);
	        }
	        }
	    });
	  btn2.addActionListener(new ActionListener() {
	        @Override
	        public void actionPerformed(ActionEvent e) {
	            new MyFrame04();
	            MyFrame02.this.dispose();
	        }
	    });
	}
public static void test01() throws IOException{
	//使用 tf1即姓名+.txt进行保存文件
	String name ="f:\\学生信息\\"+tf1.getText()+".txt";
    OutputStream os=new FileOutputStream(name);
  os.write("姓名：".getBytes());
  os.write(tf1.getText().getBytes());
  os.write("。".getBytes());

  os.write("。".getBytes());
  os.close();
}
public static void cj(){
	File f1=new File("f:\\学生信息"); 
	f1.mkdir(); //该文件不存在时，使用mkdir方法进行创建
}
}

四、注册界面 差点把这个忘了、、、

// 注册账号 界面  
public class MyFrame03 extends JFrame { 
private JTextField tf; 
private JPasswordField pf1; 
private JPasswordField pf2; 
private JLabel lb1; 
private JLabel lb2; 
private JLabel lb3; 
private JLabel lb4; 
private JButton btn1; 
private JButton btn2; 
private JPanel p=new JPanel(); 
private JPanel p1=new JPanel(); 
private JPanel p2=new JPanel(); 
private JPanel p3=new JPanel(); 
private JPanel p4=new JPanel(); 
private JPanel p5=new JPanel(); 
public void init(){
	setTitle("学生登记系统注册账号");
    setSize(300, 200);
    setLocationRelativeTo(null);
    lb1=new JLabel("  账号");
    lb2=new JLabel("  密码");
    lb3=new JLabel("  再次输入密码");
    lb4=new JLabel("注册账号");
    btn1=new JButton("确定");
    btn2=new JButton("取消");
    tf=new JTextField(20);
    pf1=new JPasswordField(20); 
    pf2=new JPasswordField(20); 
   this.setContentPane(p);
   p.setLayout(new BorderLayout());
   p1.setLayout(new FlowLayout());
   p2.setLayout(new GridLayout(3, 2));

   p1.add(lb4);
   p2.add(lb1);
   p2.add(tf);
   p2.add(lb2);
   p2.add(pf1);
   p2.add(lb3);
   p2.add(pf2);
   p3.add(btn1);
   p3.add(btn2);
   p.add(p1,BorderLayout.NORTH);
   p.add(p2,BorderLayout.CENTER);
   p.add(p3,BorderLayout.SOUTH);
   p.add(p4,BorderLayout.EAST);
   p.add(p5,BorderLayout.WEST);
}

public void add(){
    btn1.addActionListener(new ActionListener(){ 
        public void actionPerformed(ActionEvent e) {
        if (pf2.getText().toString().trim().equals(pf1.getText().toString().trim())) {
            try {
                save();
                int x=JOptionPane.showConfirmDialog(MyFrame03.this, "注册成功", "系统提示", JOptionPane.OK_CANCEL_OPTION,JOptionPane.CANCEL_OPTION);
                if(x==JOptionPane.OK_OPTION){
                    fh();
                }
            } catch (IOException e1) {
                e1.printStackTrace();
            }
        }else {
            JOptionPane.showConfirmDialog(MyFrame03.this, "输入密码不一致，请重新输入", "系统提示", JOptionPane.OK_CANCEL_OPTION,JOptionPane.CANCEL_OPTION);
            MyFrame03.this.dispose();
            new MyFrame03();
        }
        }
    });    
    btn2.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            fh();
        }
    });
}
public MyFrame03() {
   JPanel cp=(JPanel) getContentPane();
   cp.setLayout(new FlowLayout());
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    init();
    add();
    setVisible(true);
}
public void save() throws IOException{ 
	File f1=new File("f:\\信息系统账号"); 
	f1.mkdir(); 
	String name ="f:\\信息系统账号\\"+tf.getText()+".txt";
    OutputStream os=new FileOutputStream(name);
    os.write(pf1.getText().getBytes());
    os.close();
} 
public void fh(){ 
    MyFrame03.this.dispose(); 
    new MyFrame01(); 
}
}

五。查找功能

	//查找学生信息，并且将其信息输出在该界面上
public class MyFrame06 extends JFrame {
	private JButton btn1;
	private JButton btn2;
	private JTextField tf;
	public void init() {
	    setLayout(new FlowLayout());
	    setTitle("学生信息查看系统");
	    setSize(500, 500);
	    setLocationRelativeTo(null);
	}
	public void add(){
	     btn1=new JButton("确定");
	        btn1.addActionListener(new ActionListener() {

	            @Override
	            public void actionPerformed(ActionEvent e) {
	                int x=JOptionPane.showConfirmDialog(MyFrame06.this, "是否查看", "系统提示", JOptionPane.OK_CANCEL_OPTION,JOptionPane.CANCEL_OPTION);
	                if (x==JOptionPane.OK_OPTION) {
	                try {
	                    ck();
	                    MyFrame06.this.dispose();
	                } catch (IOException e1) {
	                    // TODO Auto-generated catch block
	                    e1.printStackTrace();
	                }
	            }else{
	                JOptionPane.showConfirmDialog(MyFrame06.this, "查看失败", "系统提示", JOptionPane.OK_CANCEL_OPTION,JOptionPane.CANCEL_OPTION);
	                new MyFrame06();
	            }
	            }
	        });
	        btn2=new JButton("取消");
	        btn2.addActionListener(new ActionListener() {

	            @Override
	            public void actionPerformed(ActionEvent e) {
	                MyFrame06.this.dispose();
	                new MyFrame04();
	            }
	        });
	    add(btn1);
	    add(btn2);
	}
	public  JPanel getFilePanel(){
	     JPanel p=new JPanel();
	     p.setLayout(new FlowLayout());
	     p.add(new JLabel("请输入要查找学生的名字"));
	     tf=new JTextField(10);
	     p.add(tf);
	     return p;
	}
	public MyFrame06(){
	    JPanel cp=(JPanel) getContentPane();
	    cp.setLayout(new FlowLayout());
	    cp.add(getFilePanel());
	    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	    add();
	    init();
	    setVisible(true);
	}

	public void ck() throws IOException {
	    File f=new File("f:\\学生信息");
	    String fname []=f.list();	   
	    boolean b=false;
	    for(String s:fname){
	        if (s.equals(tf.getText()+".txt")) {
	            new MyFrame07(tf.getText()+".txt");
	          b=true;
	        }
	        }
	    if (!b) {
	        JOptionPane.showConfirmDialog(MyFrame06.this, "查看失败：学生信息不存在", "系统提示", JOptionPane.OK_CANCEL_OPTION,JOptionPane.CANCEL_OPTION);
	        new MyFrame06();
	    }
	        MyFrame06.this.dispose();
	}
}

六。把查找的结果显示出来

	// 显示学生信息 
	public class MyFrame07 extends JFrame {
	private String xh; 
	private String yysx; 
	private String dxyy; 
	private String java; 
	private String jsjyy; 
	 private JButton btn1;
	 private JButton btn2;
	    public void init() {
	        setLayout(new FlowLayout());
	        setTitle("学生信息");
	        setSize(500, 500);
	        setLocationRelativeTo(null);
	    }
 public void add(){
	         btn1=new JButton("退出");
	            btn1.addActionListener(new ActionListener() {
	                public void actionPerformed(ActionEvent e) {
	                    System.exit(0);
	                }
	            });
	            btn2=new JButton("返回");
	            btn2.addActionListener(new ActionListener() {

	                public void actionPerformed(ActionEvent e) {
	                    MyFrame07.this.dispose();
	                    new MyFrame06();
	                }
	            });
	   }
	public MyFrame07(String name) throws IOException {
	    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	    init();
	     add();
	     dq(name);
	setVisible(true);

	JPanel p=new JPanel();
	JPanel p1=new JPanel();
	JPanel p2=new JPanel();
	JPanel p3=new JPanel();
	JPanel p4=new JPanel();
	setContentPane(p);

	p.setLayout(new BorderLayout());
	p1.setLayout(new GridLayout(8,1));
	p2.setLayout(new FlowLayout());

	p1.add(new JLabel(w0));
	p1.add(new JLabel(w1));
	p1.add(new JLabel(w2));
	p1.add(new JLabel(w3));
	p1.add(new JLabel(w4)); 
	p1.add(new JLabel(w5));
	p2.add(btn1);
	p2.add(btn2);
	p.add(p1,BorderLayout.CENTER);
	p.add(p2,BorderLayout.SOUTH);
	p.add(p3,BorderLayout.EAST);
	p.add(p4,BorderLayout.WEST);
	}
	String w0=null;
	String w1=null;
	String w2=null;
	String w3=null;
	String w4=null;
	String w5=null;
	 public  void dq(String name) throws IOException{
	    File f=new File("f:\\学生信息");
	    String fname []=f.list();
	        Reader r=new FileReader("f:\\学生信息\\"+name);
	        String b=null;
	        char cs[]=new char[1024*1024];
	        int len=0;
	        while ((len=r.read(cs))!=-1) {
	            b=new String(cs,0,len);
	        }
	        r.close();
	        String[] s=b.split("。");
	        w0=s[0];
	        w1=s[1];
	        w2=s[2];
	        w3=s[3];
	        w4=s[4];
	        w5=s[5];
	}
}

七、查询成绩信息，还未实现，后续更新后将补齐
