1.新建一個Student的抽象類;

package com.eduask.testabstract;
//定義一個Student抽象類;
public abstract class Student {
public abstract void stu_Id();
public abstract void stu_Name();
public abstract void stu_Pwd();
}

2.新建一個Teacher的接口;

package com.eduask.testabstract;
//定義一個Teacher接口;
public interface Teacher {
abstract void teac_Name();
}

3.新建一個Student1繼承Student類，實現(xiàn)Teacher接口;

package com.eduask.testabstract;

import org.junit.Test;

public class Student1 extends Student implements Teacher {

@Override
public void teac_Name() {
// TODO Auto-generated method stub
System.out.println("Student1的老師是tom");
}

@Override
public void stu_Id() {
// TODO Auto-generated method stub
System.out.println("Student1的id是001");
}

@Override
public void stu_Name() {
// TODO Auto-generated method stub
System.out.println("Student1的name是linux");
}

@Override
public void stu_Pwd() {
// TODO Auto-generated method stub
System.out.println("Student1的pwd是123456");
}
@Test
public void test(){
Student1 student1=new Student1();
student1.teac_Name();
student1.stu_Id();
student1.stu_Name();
student1.stu_Pwd();
}
}

4.程序運行如下:

Student1的老師是tom
Student1的id是001
Student1的name是linux
Student1的pwd是123456
