联系人信息管理小程序

刚学了Myeclipse的VE(直接拖动组件生成代码)，就写了一个关于联系人信息管理的小程序，结合了文件操作，其中遇到的问题主要就是

• 构造传参和构造接参
• 更新界面的Validate( )必须写上
• 使用对象流的时候，该对象必须序列化
• 分层设计思想和面向接口编程思想
• 模糊查询
• 打开软件加载数据，增删改查保存数据
  

程序很小，一共就几个类

效果如图：

下面给出代码，为了方便查找，就按照上面给出的包的图片顺序来放代码了

1.bean

import java.io.Serializable;

public class Linkman implements Serializable{
	private static final long serialVersionUID = 1L;
	private String name;
	private String phone;
	private String address;
	public Linkman(String name, String phone, String address) {
		super();
		this.name = name;
		this.phone = phone;
		this.address = address;
	}
	
	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getPhone() {
		return phone;
	}

	public void setPhone(String phone) {
		this.phone = phone;
	}

	public String getAddress() {
		return address;
	}

	public void setAddress(String address) {
		this.address = address;
	}

	public Linkman() {
		super();
	}
	@Override
	public String toString() {
		return name + ", " + phone + ", " + address;
	}
	@Override
	public int hashCode() {
		final int prime = 31;
		int result = 1;
		result = prime * result + ((name == null) ? 0 : name.hashCode());
		return result;
	}
	@Override
	public boolean equals(Object obj) {
		if (this == obj)
			return true;
		if (obj == null)
			return false;
		if (getClass() != obj.getClass())
			return false;
		Linkman other = (Linkman) obj;
		if (name == null) {
			if (other.name != null)
				return false;
		} else if (!name.equals(other.name))
			return false;
		return true;
	}
	
}

2.business逻辑层

3.DAO数据层

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.util.Vector;

import S07_LinkmanManage.bean.Linkman;
import S07_LinkmanManage.inte.DaoInte;

public class Dao implements DaoInte{
	//private final String FILE_PATH = "E:/test/linkman.bl";
	private final String FILE_PATH = "linkman.bl";

	/**
	 * 从文件获取所有联系人
	 */
	@Override
	public Vector getAll() {
		Vectorlist = new Vector();
		ObjectInputStream ois = null;
		try {
			ois = new ObjectInputStream(new FileInputStream(FILE_PATH));
			while(true){
				Linkman man = (Linkman) ois.readObject();
				list.add(man);
			}
		} catch (IOException e) {
		} catch (ClassNotFoundException e) {
		}finally {
			if(ois != null){
				try {
					ois.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		}
		return list;
	}

	/**
	 * 将所有联系人保存到文件
	 */
	@Override
	public boolean save(Vector list) {
		ObjectOutputStream out = null;
		try {
			out = new ObjectOutputStream(new FileOutputStream(FILE_PATH));
			for (Linkman linkman : list) {

			}
		} catch (IOException e) {

		} finally{
			if(out != null){
				try {

				} catch (IOException e) {

				}
			}
		}
		return true;

}

4.接口

import S07_LinkmanManage.bean.Linkman;
//面向接口编程
public interface DaoInte {
	public abstract boolean save(Vectorlist);
	public abstract Vector getAll();
}
