追问

谢谢大神！！我运行时提示有异常

Answer 2

class Person{
private String name;
private int age;
private String sex;
get set toString 都自己写吧
}
class Student extend Person{
属性 和 get set toString 都自己写吧
}

public class TestStudent｛
public static void main(String[] args){
Person p = new Person();
system.out.println(p);

Person s = new Student();
system.out.println(s)
}
｝

Answer 3

System.out.println("=======a======")；

Answer 4

给五分让人写程序 够大方的
