Multidimensional arrays

[Java Tip]

Multidimensional arrays are very useful while programming. Matrix operations become easier when using arrays.

String[][] array = new String[2][4];
for (int row=0;row<2;row++)
{
	for (int col=0;col<4;col++)
		array[row][col] = "Value at row: " + row + " col: " + col;
}
		
for (int row=0;row<2;row++)
{
	for (int col=0;col<4;col++)
		System.out.println(array[row][col]);
}

Output:

Value at row: 0 col: 0
Value at row: 0 col: 1
Value at row: 0 col: 2
Value at row: 0 col: 3
Value at row: 1 col: 0
Value at row: 1 col: 1
Value at row: 1 col: 2
Value at row: 1 col: 3
