类名作为返回值案例

package com.mydemo2;

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


package com.mydemo2;

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.mydemo2;

//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();
  }
}
