Here i am getting correct output but my testcases are wrong

#1

import java.util.*;
public class Main {
public static void main(String args[]) {
Scanner sc=new Scanner(System.in);
int n=sc.nextInt();
int m=sc.nextInt();
int [][]arr=new int[n][m];
for(int i=0;i<arr.length;i++){
for(int j=0;j<arr.length;j++){
arr[i][j]=sc.nextInt();
}
System.out.println();
}
columnprint(arr);
sc.close();
}
public static void columnprint(int [][]arr){
for(int i=0;i<arr.length;i++){
if(i%2==0){
for(int j=0;j<arr.length;j++){
System.out.print(arr[j][i]+", “);
}
}
else{
for(int j=arr.length-1;j>=0;j–){
System.out.print(arr[j][i]+”, ");
}
}
}
System.out.print(“END”);
}
}
