本文介绍了很好地打印Java收藏(toString不返回漂亮的输出)的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我希望像Eclipse调试器一样打印一个 Stack< Integer>
对象(即 [1,2,3 ...] ]
),但是用 out =output:+ stack
打印它不会返回这个不错的结果。
I wish to print a Stack<Integer>
object as nicely as the Eclipse debugger does (i.e. [1,2,3...]
) but printing it with out = "output:" + stack
doesn't return this nice result.
只是为了澄清,我在谈论Java的内置集合,所以我不能覆盖它的 toString()
。
Just to clarify, I'm talking about Java's built-in collection so I can't override its toString()
.
如何获得一个漂亮的可打印版本的堆栈?
How can I get a nice printable version of the stack?
推荐答案
您可以转换数组,然后使用 Arrays.toString(Object [])
打印出来:
You could convert it to an array and then print that out with Arrays.toString(Object[])
:
System.out.println(Arrays.toString(stack.toArray()));
