I WANT TO REVERSE AN ARRAY

#1 
    Scanner input=new Scanner(System.in);
    int n =input.nextInt();
    int i,a;
    int[] arr = new int[n];
    a=n-1;
    int[] ary=new int[n];
    for(i=0;i<n;i++){
        arr[i]=input.nextInt();
        if(i==a){
            ary[a]=arr[i];
            a--;
            i=i-2;
        }
    }
    for(i=0;i<n;i++){
        System.out.print(ary[i]+" ");
    }

here is the code to reverse an array
Scanner input=new Scanner(System.in);
int n =input.nextInt();
int i,a;
int[] arr = new int[n];
a=n-1;
int[] ary=new int[n];
for(i=0;i<n;i++){
arr[i]=input.nextInt();
ary[a]=arr[i];
a–;

    }
    for(i=0;i<n;i++){
        System.out.print(ary[i]+" ");
