类名作为返回值案例

package com.itheima_11;

public class Student {
    public void study() {
        System.out.println("好好学习,天天向上");
    }
}

package com.itheima_11;

public class Teacher {
    public Student getStudent() {
        Student s = new Student();
        return s;// 返回的是Student对象的地址值
    }
}

package com.itheima_11;

//需求： 通过Teacher得到Student对象，然后调用Student类的方法
//如果方法的返回值是类名，其实返回的是该类的对象
public class Test {
    public static void main(String[] args) {
        Teacher t = new Teacher();
        Student s = t.getStudent();
        s.study();
    }
}
