Java Tutorial : Java Array (Multidimensional Array - String Create and Intialize)

ArrayDemo.java

class ArrayDemo
{
    public static void main(String[] args)
    {

        String[][] strArray =
        {
        { "Ram", "Peter" },
        { "Apple", "Ball" },
        { "Bike", "Car" } };

        System.out.println("Element at strArray[0][0] : " + strArray[0][0]);
        System.out.println("Element at strArray[0][1] : " + strArray[0][1]);

        System.out.println();

        System.out.println("Element at strArray[1][0] : " + strArray[1][0]);
        System.out.println("Element at strArray[1][1] : " + strArray[1][1]);

        System.out.println();

        System.out.println("Element at strArray[2][0] : " + strArray[2][0]);
        System.out.println("Element at strArray[2][1] : " + strArray[2][1]);

    }
}

Output

Element at strArray[0][0] : Ram
Element at strArray[0][1] : Peter

Element at strArray[1][0] : Apple
Element at strArray[1][1] : Ball

Element at strArray[2][0] : Bike
Element at strArray[2][1] : Car

ArrayLoopDemo.java

public class ArrayLoopDemo
{

    public static void main(String[] args)
    {
        String[][] strArray =
            {
            { "Ram", "Peter" },
            { "Apple", "Ball" },
            { "Bike", "Car" } };
        
        int rows = strArray.length;

        System.out.println("Number of rows : " + rows+"\n");
        
        for (int i = 0; i < rows; i++)
        {
            int columns = strArray[i].length;
            
            System.out.println("Number of columns in row "+ i +" is : " + columns);
            
            for (int j = 0; j < columns; j++)
            {
                System.out.println("Element at " + "strArray[" + i + "]" + "["
                        + j + "] : " + strArray[i][j]);

            }
            System.out.println();
        }

    }

}

Output

Number of rows : 3

Number of columns in row 0 is : 2
Element at strArray[0][0] : Ram
Element at strArray[0][1] : Peter

Number of columns in row 1 is : 2
Element at strArray[1][0] : Apple
Element at strArray[1][1] : Ball

Number of columns in row 2 is : 2
Element at strArray[2][0] : Bike
Element at strArray[2][1] : Car
