// 1 倒序打印数组元素:

import java.util.Arrays;

public class Main {
	public static void main(String[] args) {
		int[] ns = { 1, 4, 9, 16, 25 };
	
		for (int i = ns.length - 1; i >= 0; i--) {
			System.out.println(ns[i]);
		}
	}
}

// 2 使用Arrays.toString()倒序打印整个数组

import java.util.Arrays;

public class Main2 {

	public static void main(String[] args) {
		
		int[] ns = { 1, 4, 9, 16, 25 };
		int[] nx = new int[ns.length];
		for (int i = ns.length - 1; i >= 0; i--) {
			nx[ns.length-1-i] = ns[i];
		}
		System.out.println(Arrays.toString(nx));

	}
