题目是这样的：

源代码是这样的：

出来的结果要这样：

我写的代码：

这节课知识点我记得很混乱，做题很懵

现在卡住了，写不下去!!求大神帮我看看怎么往下写，谢谢谢谢谢谢！！

总共四个类

package com.cwk.test;
/**
 * 教师抽象类
 *
 */
public abstract class Teacher {
    protected String name;
    public abstract void teach();
}

package com.cwk.test;
/**
 * 中学老师类
 *
 */
public class MidSchoolTeacher extends Teacher {
    private String subject;

    @Override
    public void teach() {
        System.out.println(name + "教中学生" + subject);
    }

    public MidSchoolTeacher(String name, String subject) {
        this.name = name;
        this.subject = subject;
    }

    public MidSchoolTeacher() {
        super();
    }
}

package com.cwk.test;
/**
 * 教授类
 *
 */
public class Professor extends Teacher {
    private String reseachArea;

    @Override
    public void teach() {
        System.out.println(name + "教大学生研究" + reseachArea);
    }

    public Professor(String name, String reseachArea) {
        this.name = name;
        this.reseachArea = reseachArea;
    }

    public Professor() {

    }
}

package com.cwk.test;
/**
 * 测试类
 *
 */
public class T5 {

    public static void main(String[] args) {
        Teacher teacher;
        teacher = new MidSchoolTeacher("王老师", "地理");
        teacher.teach();
        teacher = new Professor("李教授", "AI");
        teacher.teach();
    }

}

点个采纳，谢谢

private字段让子类继承不到父类的字段,你先搞懂4个类型,然后看题目name,teach是父类方法,继承到不是私有的其他属性和函数,你可以找找继承的资料看看
