用JAVA实现简单学生信息管理系统
第一部分：学生基本信息类 StudentPO.java
package studentList;
class StudentPO {
private String id;
private String name;
private String gender;
private String phone;
private String email;
private String college;
private String major;
public String getId(){
return id;
}
public void setId(String id){
this.id = id;
}
public String getName(){
return name;
}
public void setName(String name){
this.name = name;
}
public String getGender(){
return gender;
}
public void setGender(String gender){
this.gender = gender;
}
public String getPhone(){
return phone;
}
public void setPhone(String phone){
this.phone = phone;
}
public String getEmail(){
return email;
}
public void setEmail(String email){
this.email = email;
}
public String getCollege(){
return college;
}
public void setCollege(String college){
this.college = college;
}
public String getMajor(){
return major;
}
public void setMajor(String major){
this.major = major;
}
public String toString(){
return id+" "+name+" "+gender+" "+phone+" "+email+" "+college+" "+major;
}
}
第二部分：学生集合类 StudentSet.java
package studentList;
import java.util.Iterator;
import java.util.TreeSet;
import studentList.StudentComp;
class StudentSet extends TreeSet<StudentPO>{
private static final long serialVersionUID = 1L;
public StudentSet(){
super(new StudentComp());
}
public String[][] list() {
String list[][] = new String[this.size()][7];
Iterator<StudentPO> itr = this.iterator();
int i = 0;
while(itr.hasNext()){
StudentPO student = itr.next();
list[i][0] = student.getId();
list[i][1] = student.getName();
list[i][2] = student.getGender();
list[i][3] = student.getPhone();
list[i][4] = student.getEmail();
list[i][5] = student.getCollege();
list[i][6] = student.getMajor();
i++;
}
return list;
}
}
第三部分：实现按学号排序 StudentComp.java
package studentList;
import java.util.*;
import studentList.StudentPO;
class StudentComp implements Comparator<Object>{
public int compare(Object a, Object b) {
StudentPO aStudent = (StudentPO) a;
StudentPO bStudent = (StudentPO) b;
return aStudent.getId().compareTo(bStudent.getId());
}
}
