Java中数组的最小值和最大值 [英] min- and max value of an array in Java

问题描述

我正在尝试获取数组的最小值和最大值.问题是我不确定 for循环中到底发生了什么.我们用 int 创建一个 for循环.然后出现if语句以及我的问题: numbers [i] 应该是什么意思??我认为 numbers 已经指定了大小(9，通过初始化 {1,2,3，...，9} ).我们如何将其更改为 [i] ，我代表什么?

I'm trying to get the minimum and maximum value of an array. The problem is that I'm not sure what exactly happens in the for loop. We create a for loop with an int. Then comes the if statement and also my question: What should numbers[i] mean? I thought that numbers already has specified size (9, by initializing { 1,2,3,...,9}). How can we change that to [i] and what does that i stand for?

public class Array {

public static void main(String[] args) {
    int numbers[] = { 92, -108, 2, 120, 67, 4, -81, 9, 88, 1 };
    int min, max;
    min = max = numbers[0];

    for (int i = 1; i < 10; i++) {
        if (numbers[i] < min)
            min = numbers[i];
        if(numbers[i] > max){
            max = numbers[i];
        }
    }
    System.out.println("min is: " + min + "; max is: " + max);
}
}

期待您的回复

推荐答案

numbers [i] 是访问数组中 ith 元素的方式.

numbers[i] is how you access the ith element in the array.
