自己类调用自己的本来的构造函数

class Student extends Person{
private String school;

Student(String name, String location, String school) {
   super(name, location);
   this.school = school;
}

Student(String name, String school) {
   this(name, "beijing", school);            //在这个地方
}

public String info() {
   return super.info() + "school" + school;
}
}

刚开始这样调用的this.Student(name, "beijing", school);   

错误不是这样调用的应该这样 this(name, "beijing", school);
