如何从输入的一组数字中获取最大值和最小值？ [英] How do I get the max and min values from a set of numbers entered?

问题描述

以下是我目前的情况：

我不知道如何排除0作为最小数字。赋值要求0为退出号，因此我需要在min字符串中出现0以外的最小数字。有什么想法吗？

I don't know how to exclude 0 as a min number though. The assignment asks for 0 to be the exit number so I need to have the lowest number other than 0 appear in the min string. Any ideas?

int min, max;

Scanner s = new Scanner(System.in);
System.out.print("Enter a Value: ");
int val = s.nextInt();
min = max = val;

while (val != 0) {
  System.out.print("Enter a Value: ");
  val = s.nextInt();
  if (val < min) {
      min = val;
  }
  if (val > max) {
     max = val;
  }
};
System.out.println("Min: " + min);
System.out.println("Max: " + max);

推荐答案

您只需要跟踪最大值这个：

You just need to keep track of a max value like this:

int maxValue = 0;

然后在迭代数字时，如果maxValue大于，则继续将maxValue设置为下一个值maxValue：

Then as you iterate through the numbers, keep setting the maxValue to the next value if it is greater than the maxValue:

if (value > maxValue) {
    maxValue = value;
}

对minValue重复相反的方向。

Repeat in the opposite direction for minValue.
