求问关于super的用法和构造函数，是关于java的问题！

Question

能编译通过，但是结果不对，不知道是哪里错了class Person{private String name;private String location; Person(String name){this.name=name;location="beijing";}Person(String name,String location){this.name=name;this.location=location;}public String info(){return "name:"+name+"location:"+location;}}class Student extends Person{private String school;Student(String name,String school){this(name,school,"beijing"); }Student(String n,String l,String school){super(n,l);this.school=school;}public String info(){return super.info()+" school:"+school; }}

Answer 1

程序没有问题,
子类可以通过父类的构造方法完成对父类的变量的赋值。
不知你的main()方法是怎么写的，
是不是main()方法有问题？

Answer 2

没有main方法，程序怎么执行？
