一个用java实现输入一维数组并倒序的简便算法

import java.util.Scanner;
public class daoxu{
	public static void main(String[] args)
	{
		int N,x,temp,j,i,p;
		int[] a;
		System.out.println("请输入数组个数：");
		 Scanner scanner = new Scanner(System.in);
		 x=Integer.parseInt(scanner.next());
         a=new int[x];
         System.out.print("请依次输入"+x+"个整数：");
         for(i=0;i<x;i++)
        {    
        	 a[i]=Integer.parseInt(scanner.next());
        }
        
        p=x/2;
        for(i=0,j=x-1;i<=p && j>i;i++,j--)
        {
        	temp=a[i];
        	a[i]=a[j];
        	a[j]=temp;
        }
        
        System.out.println("倒序后的数组是：");
        for(i=0;i<x;i++)
        System.out.print(a[i]+"  ");
        
		
	}
}
