使用预定义的Java方法查找数组中的最大数字 [英] Finding the largest number in an array using predefined java methods

问题描述

这是我正在处理的代码段，我的目标是使用预定义的Java方法从列表中找到最大值.

Here is the code snippet that I am working on and my goal is to find the largest value from the list using predefined java methods.

import java.util.*;

public class Test {
    public static void main(String[] args) {
        Scanner s = new Scanner(System.in);
        System.out.println("Enter a list of integers: ");
        int array[] = new int[10];

        for (int i = 0; i < array.length; i++) {
            array[i] = s.nextInt();
        }

        for (int j = 0; j < array.length; j++) {
            if (j < array.length) {
                int maximum = Math.max(array[j], array[j + 1]);
            }
        }

        System.out.println("Largest number of the list: " + maximum);
    }
}

我得到的错误如下:

Exception in thread "main" java.lang.Error: Unresolved compilation problem:
        maximum cannot be resolved to a variable

我希望有人能帮助我解决这个问题.

I hope someone can help me resolve this.

推荐答案

您可以仅迭代数字数组并跟踪看到的最大值:

You may just iterate the array of numbers and keep track of the largest value seen:

int largest = Integer.MIN_VALUE;

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

注意:上面的代码段假定您在输入数组中至少有一个数字.

Note: The above snippet assumes that you have at least one number in the input array.
