Waveprint - same error is coming again

import java.util.*;
public class Main {
public static void main(String args[]) {

@Naman_Gupta,

	public static void main(String args[]) {
		Scanner sc = new Scanner(System.in);
		int M = sc.nextInt();
		int N = sc.nextInt();
		
		// array declaration
		int[][] arr = new int[M][N];
		for (int i = 0; i < M; i++) {
//			arr[i] = new int[N];
			for (int j = 0; j < N; j++) {
				arr[i][j] = sc.nextInt();
			}
		}
		
		Waveprint(arr);

	}

Take input of the array elements and call the waveprint function.
You can refer to the code snippet above.

yes i have taking input of the array elements and call the waveprint function but still it is coming

@Naman_Gupta,
In the code that you shared above, you are not doing that. Also, I cannot see any new submissions that you have made.
