一个简单的学生管理系统项目
简介
初学不久，做了一个学生管理系统，学生主要包括学号、姓名、年龄和住址属性，项目主要完成对学生信息的添加、修改和删除操作，并且还可显示所有学生的学生信息，对于学生的其他属性或者管理操作，读者也可根据此项目再进行添加
学生类
package com.softeem.lesson07.test3;
public class student {
String sno;
String sname;
int sage;
String address;
public student() {
super();
}
public student(String sno, String sname, int sage, String address) {
super();
this.sno = sno;
this.sname = sname;
this.sage = sage;
this.address = address;
}
public String getSno() {
return sno;
}
public void setSno(String sno) {
this.sno = sno;
}
public String getSname() {
return sname;
}
public void setSname(String sname) {
this.sname = sname;
}
public int getSage() {
return sage;
}
public void setSage(int sage) {
this.sage = sage;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}
管理类

import java.util.ArrayList;

public static void scan() {

System.out.println(stu.getSno() + "\t" + stu.getSname() + "\t" + stu.getSage() + "\t" + stu.getAddress());

list.add(stu);
System.out.println("添加成功");
}
public static void delete() {
System.out.println("请输入要删除的学生学号");
String n = scanner.next();
boolean flag = false;
for (int i = 0; i < list.size(); i++) {
student stu = list.get(i);
if (n.equals(stu.getSno())) {
flag = true;
list.remove(i);
break;
}
}
if (flag) {
System.out.println("删除成功");
} else {
System.out.println("未删除成功");
}
}
static void update() {
System.out.println("请输入要修改的学生学号");
String n = scanner.next();
boolean flag = false;
for (int i = 0; i < list.size(); i++) {
student stu = list.get(i);
if (n.equals(stu.getSno())) {
flag = true;
System.out.println("请输入学生新学号");
stu.sno = scanner.next();
System.out.println("请输入学生新姓名");
stu.sname = scanner.next();
System.out.println("请输入学生新年龄");
stu.sage = scanner.nextInt();
System.out.println("请输入学生新住址");
stu.address = scanner.next();
list.set(i, stu);
break;
}
}
if (flag) {
System.out.println("修改成功");
} else {
System.out.println("未修改成功");
}
}
static void out() {
tag = false;
System.out.println("谢谢您的使用");
}
public static void main(String[] args) {
while (tag) {
System.out.println("------欢迎来到学生管理系统------");
System.out.println("1 查看所有学生信息");
System.out.println("2 添加学生信息");
System.out.println("3 删除学生信息");
System.out.println("4 修改学生信息");
System.out.println("5 退出");
System.out.println("请输入你的选择");
int choice1, choice2;
choice1 = scanner.nextInt();
switch (choice1) {
case 1:
scan();
break;
case 2:
add();
break;
case 3:
delete();
break;
case 4:
update();
break;
case 5:
out();
break;
}
}
}
}
运行结果
由于只是刚刚入学，代码不能做到相当简洁，如有建议或者有什么可以修改的地方，欢迎评论。
