方法的跳轉-考試出錯點

package com.beifeng.other;

public class Test1 {
    public static void main(String[] args) {

        new Student();
    }
}
//bbbb  ccc  aaa
class Student {
    String name;
    String number;

    Student() {
        this("無名","-1");
        System.out.println("aaa");
    }
    Student(String name) {
        this.name = name;
        System.out.println("bbb");
    }
    Student(String name,String number) {
        this(name);
        this.number = number;
        System.out.println("ccc");
    }
