java如何实现简单学生管理系统项目 java实现简单学生管理系统项目代码实例

本篇文章小编给大家分享一下java实现简单学生管理系统项目代码实例，文章代码介绍的很详细，小编觉得挺不错的，现在分享给大家供大家参考，有需要的小伙伴们可以来看看。

功能：

1、增加学生

2、查看学生

3、根据学号修改学生信息

4、根据学号查看某一个学生信息

5、根据性别查看同性别的所有学生

6、根据学号删除某一个学生

7、按照学号升序排序(默认)

8、按照年龄降序排序

Student 类- - -学生的javabean类

package com.studentByArray.www;

public class Student {
 
 //定义一个Student类{学号、姓名、年龄、性别}
 private String Sno;
 
 private String name;
 
 private int age;
 
 private String sex;
 
 
 
 public Student() {
 super();
 // TODO Auto-generated constructor stub
 }

 public Student(String sno, String name, int age, String sex) {
 super();
 Sno = sno;
 this.name = name;
 this.age = age;
 this.sex = sex;
 }
 
 public String getSno() {
 return Sno;
 }
 public void setSno(String Sno) {
 this.Sno = Sno;
 }
 
 public String getName() {
 return name;
 }
 public void setName(String name) {
 this.name = name;
 }
 
 public int getAge() {
 return age;
 }
 public void setAge(int age) {
 this.age = age;
 }
 
 public String getSex() {
 return sex;
 }
 public void setSex(String sex) {
 this.sex = sex;
 }
 @Override
 public String toString() {
 return "Student [Sno=" + Sno + ", name=" + name + ", age=" + age + ", sex=" + sex + "]";
 } 
 

}

StudentOperate 类- - -学生管理系统功能实现类

package com.studentByArray.www;

import java.util.ArrayList;

public class StudentOperate {
 
 ArrayList list = new ArrayList();
 
 //增加学生
 public boolean addStudent(Student student) {
 
 for(int i=0;i selectStuByAge(String sex) {
 ArrayList newStu = new ArrayList();
 for(int i=0;i sortBySno() {
 for(int i=0;i0) {
 Student temp = list.get(j);
 list.set(j, list.get(j+1));
 list.set(j+1, temp);
 
 }
 
 }
 
 }
 return list;
 
 
 }
 
 //按照年龄降序排序
 public ArrayList sortByAge() {
 for(int i=0;i

	StudentTest 类- - -操作界面测试类

package com.studentByArray.www;

 case 4:
