用java写的学生信息管理系统，供大家参考，具体内容如下

使用到了集合类ArrayLisat 来对Student类的对象进行存储。

StudentManagerTest为主类，Student类里面进行了相应数据的封装。里面用了很多循环来写，并且运用了很多标记来进行判断是否退出循环，如flag和index。

创建集合类对象格式：

ArrayList array= new ArrayList();在传递方法的时候需要在形参列表中用<>对传递的类型进行明确

主类

package zjh; import java.util.ArrayList; import java.util.Scanner; public class StudentManageTest { public static void main(String[] args) { ArrayList<Student> array = new ArrayList<Student>(); while(true) { System.out.println("----欢迎来到学生信息管理系统----"); System.out.println("请输入你想要进行的操作"); 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"); Scanner scanner = new Scanner(System.in); String choice = scanner.nextLine(); switch (choice) { case "1": findAllStudents(array); break; case "2": addStudent(array); break; case "3": deleteStudent(array); break; case "4": updateStudent(array); break; case "5": default: System.out.println("正在退出系统，欢迎下次继续使用"); break; } } } //修改学生信息 public static void updateStudent(ArrayList<Student> array) { Scanner scanner = new Scanner(System.in); while(true) { System.out.println("请输入你要修改的学号："); String id = scanner.nextLine(); int index = -1; for(int x=0; x<array.size(); x++) { Student student = array.get(x); if(student.getId().equals(id)) { index = x; break; } } if(index ==-1) { System.out.println("您输入的学号有误请重新输入"); continue; }else { System.out.println("请输入新的姓名："); String name = scanner.nextLine(); System.out.println("请输入新的年龄："); String age = scanner.nextLine(); System.out.println("请输入新的地址"); String address = scanner.nextLine(); Student student = new Student(); student.setId(id); student.setName(name); student.setAge(age); student.setAddress(address); array.set(index, student); break; } } System.out.println("修改学生成功"); } //删除学生信息 public static void deleteStudent(ArrayList<Student> array) { Scanner scanner = new Scanner(System.in); while(true) { System.out.println("请输入你要删除的学号"); String id = scanner.nextLine(); int index = -1; for(int x=0; x<array.size(); x++) { Student student = array.get(x); if (student.getId().equals(id)) { index = x; break; } } if(index == -1) { System.out.println("您输入的学号有误 请重新输入"); continue; }else { array.remove(index); break; } } System.out.println("删除学生信息成功！"); } //添加学生信息 public static void addStudent(ArrayList<Student> array) { Scanner scanner = new Scanner(System.in); String id; while(true) { System.out.println("请输入你要添加的学号:"); int flag =0; id = scanner.nextLine(); for(int x=0; x<array.size(); x++) { Student student =array.get(x); if(student.getId().equals(id)) { System.out.println("你输入的学号已被占用，请重新输入"); break; }else { flag++; } } if(flag==array.size()) { break; } } System.out.println("请输入你要添加的姓名："); String name = scanner.nextLine(); System.out.println("请输入你要添加的年龄："); String age = scanner.nextLine(); System.out.println("请输入你要添加的地址："); String address = scanner.nextLine(); Student student = new Student(); student.setId(id); student.setName(name); student.setAge(age); student.setAddress(address); array.add(student); System.out.println("添加信息成功"); } //查看所有学生信息 public static void findAllStudents(ArrayList<Student> array) { if(array.size()==0) { System.out.println("当前没有任何学生信息，请添加后再使用"); } System.out.println("学号\t\t姓名\t年龄\t居住地"); for(int x=0; x<array.size(); x++) { Student s = array.get(x); System.out.println(s.getId()+"\t"+s.getName()+"\t"+s.getAge()+"\t"+s.getAddress()); } }}

Student类

package zjh; public class Student { private String id; private String name; private String age; private String address; public Student() { } public Student(String id, String name, String age, String address) { this.id = id; this.name = name; this.age = age; this.address = address; } 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 getAge() { return age; } public void setAge(String age) { this.age = age; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } }
