Create a File ReverseArray.java using your favorite editor I am using Geany (Kubuntu 18.04 LTS). Compile and run the code give below you will able to see the output given in the screenshot.
Screen shot
import java.io.*; import java.util.Scanner; class ReverseArray { public static void main(String args[]) { int i,n,temp; Scanner in=new Scanner(System.in); System.out.println("Enter a range: "); n=in.nextInt(); int a[]=new int[n]; System.out.println("Enter Elements: "); for(i=0;i<n;i++) a[i]=in.nextInt(); if(n<1) System.out.println("Invalid Entry"); else for(i=0;i<n/2;i++) { temp=a[i]; a[i]=a[n-1-i]; a[n -1 - i]= temp; } for(i=0;i<n;i++) System.out.print(" "+a[i]); } }
