数组倒序输出

java数组的熟悉

public class Reverse { public static int [] rev(int [] array) {    int k=array.length;    int j=k;    int [] result=new int [array.length];    for(int i=0;i<k;i++) {        result[i]=array[j-1];        j--;    }    return result;}  public static void main(String[] args){     int[] b= {1,2,3,4,5,6,7};     for (int i : b) {         System.out.print(i+" ");     }     System.out.println( );    int []a= rev(b);     for (int i : a) {         System.out.print(i+" ");     } }}
