程序执行的结果是输出了内部编码，怎样才能输出正确信息呢，多谢
public class Equals_toString1 {

}
public boolean equals_(Equals_toString1 a) {

}
public String toString() {
return name + "" + id + "" + number；
}
public static void main(String[] args) {
Equals_toString1 a = new Equals_toString1("张三", "123456789",1521670267);
System.out.println(a);
System.out.println(a.equals("123456789"));
}
}
修改了一下程序，输出的却是flase,ID不是一样吗，怎么回事啊，哪位再补充一下，多谢
