我的程序打印出奇怪的结果：循环@ 530daa循环@ 530daa循环@ a62fc3循环@ a62fc3 [英] My program prints out weird results: cycle@530daa cycle@530daa cycle@a62fc3 cycle@a62fc3
问题描述
为什么会发生这种情况还是有特殊原因还是出于很多不同的原因？我不知道为什么我的程序打印出它正在打印的值，因为我希望它打印出整数。相反，我得到这个：
Is there a particular reason why this would happen or can it be for a lot of different reasons? I have no idea why my program is printing out the values that it is printing, because I was expecting it to print out integers. Instead I am getting this:
循环@ 173a10f
循环@ a62fc3
循环@ a62fc3
循环@ a62fc3
循环@ 530daa
cycle @ a62fc3
cycle @ a62fc3
cycle @ 530daa
cycle @ a62fc3
cycle@173a10f cycle@a62fc3 cycle@a62fc3 cycle@a62fc3 cycle@530daa cycle@a62fc3 cycle@a62fc3 cycle@530daa cycle@a62fc3
这是代码:(我也有一个循环类，一个堆栈和队列类）

推荐答案
在某处您正在打印循环对象，因为您还没有覆盖 cycle.toString（），它使用默认 toString 实施。
Somewhere you're printing cycle objects, and since you haven't overridden cycle.toString(), it's using the default toString implementation.
覆盖 toString 类的方法，你需要编写如下代码：
To override the toString method of a class, you would need to write some code like below:
class Xxx {
@Override
public String toString() {
StringBuilder sb = new StringBuilder();
sb.append("Your");
sb.append("Logic Here");
return sb.toString();
}
}
