how to print a 2d array in java

for (int row = 0; row < arr.length; row++)//Cycles through rows
{
  for (int col = 0; col < arr[row].length; col++)//Cycles through columns
  {
    System.out.printf("%5d", arr[row][col]); //change the %5d to however much space you want
  }
  System.out.println(); //Makes a new row
}
//This allows you to print the array as matrix
