java数组05数组的使用
package com.Leo.array;
public class ArrayDemo04 {
public static void main(String[] args) {
int[] arrays = {1,2,3,4,5};
//
// //JDK1.5 没有下标
// for (int array : arrays) {
// System.out.println(array);
// }
//printArray(arrays);
int[] reverse = reverse(arrays);
printArray(reverse);
}
//反转数组
public static int[] reverse(int[] arrays){
int[] result = new int[arrays.length];
//反转的操作
for (int i = 0,j=result.length-1; i < arrays.length ; i++,j--) {
result[j] = arrays[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.print(arrays[i]+" ");
}
}
