如果要多次获取数据，则应使用while

主要的JAVA

import java.util.*;

public class Main
{
    public static void main(String[] args)
    {
        Scanner scanner = new Scanner(System.in);
        
        Teacher teacher = new Teacher();
        
        int count = 0;
        while (count < 3){
            switch (count){
                case 0:
                    System.out.println("enter the id : ");
                    teacher.setId(scanner.nextInt());
                    break;
                case 1:
                    System.out.println("enter teacher name : ");
                    teacher.setName(scanner.next());
                    break;
                case 2:
                    System.out.println("enter the department : ");
                    teacher.setDepartment(scanner.next());
                    break;
            }
            count++;
        }
        
        System.out.println("id : " + teacher.getId());
        System.out.println("name : " + teacher.getName());
        System.out.println("department : " + teacher.getDepartment());
        
    }
}

教师JAVA

public class Teacher
{
    private int id;
    private String name , department;
    
    public void setId(int id){
        this.id = id;
    }
    
    public void setName(String name){
        this.name = name;
    }
    
    public void setDepartment(String department){
        this.department = department;
    }
    
    public int getId(){
        return id;
    }

    public String getName(){
        return name;
    }
    
    public String getDepartment(){
        return department;
    }
}
