Java method of outputting an array inverse order

topic:

Output an array inversely.

Code:

 import java.util.*;public class lianxi31 {public static void main(String[] args) { Scanner s = new Scanner(System.in); int a[] = new int[20];System.out.println("Please enter multiple positive integers (input -1 means end):"); int i=0,j; do{ a[i]=s.nextInt(); i++; }while (a[i-1]!=-1); System.out.println("The array you enter is:"); for( j=0; j<i-1; j++) { System.out.print(a[j]+" ");} System.out.println("/n array inverse order output is: "); for( j=i-2; j>=0; j=j-1) { System.out.print(a[j]+" ");} } }

The above java method of outputting an array in reverse order is all the content I share with you. I hope you can give you a reference and I hope you can support Wulin.com more.
