2d string array in java code example

Example 1: how to fill a 2d array in java

int rows = 5, column = 7;
int[][] arr = new int[rows][column]; 
   
   //2D arrays are row major, so always row first
   
for (int row = 0; row < arr.length; row++)
{
	for (int col = 0; col < arr[row].length; col++)
    {
    	arr[row][col] = 5; //Whatever value you want to set them to
    }
}

Example 2: declare matrix in java

int[][] multi = new int[5][];
multi[0] = new int[10];
multi[1] = new int[10];
multi[2] = new int[10];
multi[3] = new int[10];
multi[4] = new int[10];

Example 3: can strings be used in a 2 dimensional array in java

String myTwoDimensionalStringArray[][] = new String[2][2];
myTwoDimensionalStringArray[0][0] = "Apple";
myTwoDimensionalStringArray[0][1] = "Banana";
myTwoDimensionalStringArray[1][0] = "Pork";
myTwoDimensionalStringArray[1][1] = "Beef";
