用java代码将数组元素顺序颠倒

package test;

public class Recover {

    public int[] reverse(int[] a) {
        int[] b = new int[a.length];
        int n = a.length - 1;
        for (int i = 0; i < a.length; i++) {
            b[n] = a[i];
            n--;
        }
        return b;
    }  

    public static void main(String[] args) {
        Recover t = new Recover();
        int[] a = {1, 2, 3, 4, 5};
        int[] b = t.reverse(a);
        for (int i = 0; i < b.length; i++)
            System.out.print(b[i]+",");
    }  

}
