How can i print my array using Arrays.toString(reverse) without[]

Question

how can i print the result without brackets

public class Solution {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int n = in.nextInt();
        int[] arr = new int[n];
        for(int i=0; i < n; i++){
            arr[i] = in.nextInt();

        }

        int[] reverse =new int[n];
       for (int i = 0; i < reverse.length; i++) {
        reverse[i]=arr[arr.length-1-i];
    }
             in.close();
    }
}

That's like asking how can I print [] without printing []. Don't use Arrays.toString if you don't want the [] — Eran

Use String#substring for removing surrounding brackets from your string. Call str = str.substring(1, str.length() - 1); — Alexey Subach

In java8, you can conveniently do any kind of String output using join, there you will have to do some manual reversing though:

String output = String.join(", ", arr);

You can't change the implementation of Arrays.toString() so you can't print your array like that.

Although, you can assign it to an string variable and then manipulate that string as you desire.

String str = Arrays.toString(reverse);
str = str.substring(1, str.length() - 1);
