【Java菜鸟日记8】数组跟练数组反转

前言

继续学习狂神java

开始

package com.Mycode;

public class ReverseArray {
    public static void main(String[] args) {
        int[] arrays = {1, 2, 3, 4, 5};
        for (int array : arrays) {
            System.out.print(array);
        }
        System.out.println();
        for (int array : reverseArray(arrays)) {
            System.out.print(array);
        }
    }

    public static int[] reverseArray(int[] arrays) {
        int[] temp;
        temp = new int[arrays.length];
        for (int i = 0, j = arrays.length - 1; i < arrays.length; i++, j--) {
            temp[j] = arrays[i];
        }
        return temp;
    }
}

熟悉了for的数组遍历，总体难度不大
