java实现数组逆序

public class Reverse {public static void main(String[] args) {// TODO Auto-generated method stubint[] a={1,2,3,4};for(int x:a){System.out.print(x+"\t");}System.out.println();for(int i=0;i<a.length/2;i++){int temp=a[i];temp=a[i];a[i]=a[a.length-1-i];a[a.length-1-i]=temp;}for(int x:a){System.out.print(x+"\t");}}}
