Logic in Java for reversing an array

  Scanner scan = new Scanner(System.in);
         int N = scan.nextInt();
       int[] arr =  new int[N];
        for(int i=0;i<arr.length;i++)
        {
            arr[i] = scan.nextInt();
        }
        for(int i = arr.length-1;i>=0;i--)
        {
            System.out.print(arr[i]+" ");
        }

       

        scan.close();

!/bin/python3

import os import math import re import random import sys

n = int(input())

myList = list(map(int, input().rstrip().split()))

myList.reverse()

print(*myList)

JAVA-

import java.util.Scanner; public class Solution{

public static void reverse(int num[]){
     int start=0; int end =num.length-1;
     while(start<end){
        int temp=num[end];
        num[end]= num[start];
        num[start]= temp;
        start++;
        end--;


     }


}

public static void main(String[]arg){
     Scanner sc = new Scanner(System.in);
     int size = sc.nextInt();
     int num[]=new int[size];

     for(int i=0; i<size; i++){
         num[i]=sc.nextInt();
     }
     reverse(num);
     for(int i=0; i<num.length;i++){
         System.out.print(num[i]+" ");

     }
     sc.close();



}

}

this is my code in c without predefined code ---->>>

include

int main() { int n; scanf("%d",&n); int A[n]; for(int i=0;i=0;i--) { printf("%d ",A[i]); } return 0; }
