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

print 2d array in java

int[][] array = new int[rows][columns];
System.out.println(Arrays.deepToString(array));

printing 2d array in java

public class Sample {

        String roles[][] = {
                { "admin", "customer", "cashier", "manager" },
                { "Jasmine", "lyka", "marbie", "soleen" },
                { "mama", "papa", "jenilyn", "efren" }
        };
        for (int i = 0; i < roles.length; i++) {
            for (int j = 0; j < roles[i].length; j++) {
                System.out.println(roles[i][j] + " ");
            }
            System.out.println("");
        }
    }

}

java print 2d array as table

static void debugV2(Object... obj) {
        System.out.println(Arrays.deepToString(obj)
                .replace("],", "
").replace(",", "	")
                .replaceAll("[[]]", " "));
    }

    static void debug(Object... obj) {
        System.err.println(Arrays.deepToString(obj).replace("], ", "]
"));
    }

java print 2d array row and column

public class TwoDimensionalArrays
{
public static void main (String args[])
{
    final int size1 = 2, size2 = 4, size3 = 5;
    int [][] numbers = {{20,25,34,19,33}, {11,17,15,45,26}, {27,22,9,41,13}};        
    int row = 0, col = 0;

        for(row = 0; row <= size1; row++); //loops through rows
        {
            for(col = 0; col <= size2; col++); //loops through columns
            {
                System.out.println(numbers[row][col]);
            }
        System.out.print("
"); //takes a new line before each new print
        }
    }
 }
