Day17数组的使用

package com.cc.array;public class ArrayDemo4 {public static void main(String[] args) {int [] arrays = {1,2,3,4,5};//jdk1.5之后的版本可以通果增强for寻循环来遍历数组或集合中的每一个元素//缺点在于没有下标//for(int array:arrays){//  System.out.println(array);printArray(arrays);int[] resver = reverse(arrays);}//反转数组public static int[] reverse(int[] arrays){int [] result = new int[arrays.length];for(int i = 0,j = result.length-1;i < arrays.length;i++,j--){//减一防止下标越界result[i] = arrays[j];System.out.println(result[i]);}return result;}//打印数组元素public static void printArray(int [] arrays) {for(int i = 0;i < arrays.length;i++){System.out.println(arrays[i]);}}
