通过阵列的Java循环 [英] Java loop through array

问题描述

我在这里有这个循环

 for(int i =0; i < prices.length; i++)
  {
        if(prices[i]>largest)
        {
            largest = prices[i];
        }

        else if(prices[i]<smallest)
        {
            smallest= prices[i];
        }
  }

这遍历整个数组，发现最小和最大的价值。说我通过第一20个元素我怎么做，想只循环？我已经把沿线嵌套循环下for循环，看到的线尝试，如果我遇到它，但我做不到。

which loops through the whole array and finds the min and max value. Say I wanted to only loop through the first 20 elements how do I do that? I have tried along the lines of putting a nested loop in under this for loop and seeing if I come across it but I can't.

推荐答案

您只需要添加的要求，循环控制条件：

You could just add the requirement to the loop control condition:

for(int i =0; i < prices.length && i < 20; i++)

这将检查的第20个元素，其中疗法均超过20阵列中，但整个数组，如果有少于20项。

This would check the first 20 elements where ther are more than 20 in the array, but the whole array if there are less than 20 items.
