如何结束java中整数收集数组的while循环？
我正在编写一个程序，要求用户提供他们想要的任何值，只要它是整数，并且该值将被放置在一个数组中。他们可以按照自己的意愿多次执行此操作，直到将 -1 添加到数组中。我很难弄清楚如何结束循环。 我的代码：
int i = 0;
while (i != -1) {
System.out.print("Enter a positive whole number, enter '-1' to stop:");
s = scan.next();
if (i ! = -1)
intElements.add(i);
我认为问题出在我的 if 条件中。不确定写出逻辑的正确方法是什么。
I am wring a program that askes the user to give any value they want as long as it is a whole number, and that value will be placed in a array. They can do this asmany times as they would like, until they add -1 to the array. I am having a hard time figurig out how to get the loop to end.
My code:
int i = 0;
while (i != -1) {
System.out.print("Enter a positive whole number, enter '-1' to stop:");
s = scan.next();
if (i ! = -1)
intElements.add(i);
I think the issue is in my if conditional. Not sure what the correct way to write out the logic would be.

如果您只想添加正整数，请将
if语句更改为：Just change:

If you only want POSITIVE ints to be added, then also change your
ifstatement to:
