Java Stack方法(multipop)初学者java [英] Java Stack method (multipop) Beginner java

问题描述

我正在尝试编写Java方法以在堆栈上进行多播".

I'm trying to write a Java method to preform a "multi-pop" off a stack.

它应在stack对象k上执行弹出"操作的次数.这就是我的想法，但这并不完全正确.有帮助吗?

It should perform a "pop" operation on a stack object k number of times. This is what I'm thinking, but it's not quite right. Any help out there?

public void multipop(int k) {
    while (top != null) {
        for (int i = 0; i <= k; i++) {
            this.pop();
        }
    }
}

推荐答案

看起来像是一个错误的错误.

Looks like an off-by-one error.

如果是k=1，您将通过i=0和i=1进行循环.您可以通过将i<=k更改为i<k

If k=1, you will go through the loop with i=0 and i=1. You can fix this by changing i<=k to i<k
