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 matrixjava 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("\n"); //takes a new line before each new print
}
}
