Arrays-wave print row challenges

#1

output is right but still my code does not pass any test cases
package challengesArrays;
import java.util.Scanner;
public class WAve {

public static void main(String[] args) {
	// TODO Auto-generated method stub
	Scanner sc = new Scanner(System.in);

	int n = sc.nextInt();
	int m = sc.nextInt();
	if(n>1 && n<10 && m>1 && m<10)
	{
	int[][] arr = new int[n][m];
	for(int i =0 ; i<n;i++)
	{
		for(int j=0;j<m;j++)
		{
			arr[i][j] = sc.nextInt();
		}
	}
	waves(arr);
	}
	
}


public static void waves(int[][] arr)
{
	for(int i=0; i<arr.length;i++)
	{
		if(i%2==0)
		{
			for(int j=0 ; j<arr[i].length;j++)
			{
				System.out.print(arr[i][j]+",");
			}
		}
		else
		{
			for(int j = arr[i].length-1;j>=0;j--)
			{
				System.out.print(arr[i][j]+",");
			}
		}
	}
	System.out.print("END");
}

}
