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 @ 530daa

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。
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();
}
}
