这篇文章主要介绍了java实现简单学生管理系统项目，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
本文实例为大家分享了java实现简单学生管理系统的具体代码，供大家参考，具体内容如下
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
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; import java.util.ArrayList; import java.util.Scanner; public class StudentTest { public static void main(String[] args) { StudentOperate stuO = new StudentOperate(); Scanner input = new Scanner(system.in); boolean choose = true; while(choose) { System.out.println("1.增加学生"); System.out.println("2.查看学生"); System.out.println("3.根据学号修改学生信息"); System.out.println("4.根据学号查看某一个学生信息"); System.out.println("5.根据性别查看同性别的所有学生"); System.out.println("6.根据学号删除某一个学生"); System.out.println("7.按照学号升序排序(默认)"); System.out.println("8.按照年龄降序排序"); System.out.print("请输入你的选择："); int i = input.nextInt(); switch(i){ case 1: { System.out.println("请输入你要增加的学生学号："); String sno = input.next(); System.out.println("请输入要增加的学生姓名："); String name = input.next(); System.out.println("请输入要增加的学生年龄："); int age = input.nextInt(); System.out.println("请输入要增加的学生性别："); String sex = input.next(); Student stu = new Student(); stu.setSno(sno); stu.setName(name); stu.setAge(age); stu.setSex(sex); boolean receive = stuO.addStudent(stu); if(receive) { System.out.println("添加成功！"); }else { System.out.println("输入的学号已存在！"); } System.out.println("请问是否继续：(true/false)"); choose = input.nextBoolean(); break; } case 2: { stuO.showStudent(); System.out.println("请问是否继续：(true/false)"); choose = input.nextBoolean(); break; } case 3: { System.out.println("请输入你要修改的学生学号："); String sno = input.next(); System.out.println("将学生姓名改为："); String name = input.next(); System.out.println("将学生年龄改为："); int age = input.nextInt(); System.out.println("将学生性别改为："); String sex = input.next(); Student stu = new Student(); stu.setSno(sno); stu.setName(name); stu.setAge(age); stu.setSex(sex); boolean receive = stuO.updataBySno(stu); if(receive) { System.out.println("修改成功！"); }else { System.out.println("修改失败！"); } System.out.println("请问是否继续：(true/false)"); choose = input.nextBoolean(); break; } case 4: { System.out.println("请输入要查询的学生学号："); String sno = input.next(); Student receive = stuO.showStuBySno(sno); if(receive!=null) { // String stu = receive.toString(); System.out.println(receive); }else { System.out.println("没有查询到此学生！"); } System.out.println("请问是否继续：(true/false)"); choose = input.nextBoolean(); break; } case 5: { System.out.println("请输入你要查询的学生性别："); String sex = input.next(); ArrayList newStu= stuO.selectStuByAge(sex); System.out.println(newStu); System.out.println("请问是否继续：(true/false)"); choose = input.nextBoolean(); break; } case 6: { System.out.println("请输入要删除的学生学号："); String sno = input.next(); boolean receive = stuO.deleteBySno(sno); if(receive) { System.out.println("删除成功！"); }else { System.out.println("删除失败！"); } System.out.println("请问是否继续：(true/false)"); choose = input.nextBoolean(); break; } case 7: { ArrayList stus = stuO.sortBySno(); System.out.println(stus); System.out.println("请问是否继续：(true/false)"); choose = input.nextBoolean(); break; } case 8: { ArrayList stus = stuO.sortByAge(); System.out.println(stus); System.out.println("请问是否继续：(true/false)"); choose = input.nextBoolean(); break; } } } } }
