2D Java array- how to input values

Question

I am a 1st year student, and I don't know what to do here. I have input values but I keep getting 0 as a result. I am expecting output like this:

but it keeps on giving me 0.

Here is my code so far:

    String [][]array2D = new String[5][10];

    for(int r=0; r<array2D.length; r++)
    {
        for(int b=0; b<array2D[r].length; b++)
        {
            System.out.print(array2D[r][b]);    
        }
        System.out.println();
    }

    System.out.println("Prepared By: Mark Vincent D. Yap");
}

This gives the desired result:

    String [][]array2D = new String[5][10];

    for(int r=0; r<array2D.length; r++)
    {
        for(int b=0; b<array2D[r].length; b++)
        {
            array2D[r][b] = Integer.toString(r);
        }
        System.out.println();
    }

    for(int r=0; r<array2D.length; r++)
    {
        for(int b=0; b<array2D[r].length; b++)
        {
            System.out.print(array2D[r][b]);
        }
        System.out.println();
    }

    System.out.println("Prepared By: Diligent Key Presser");

Hope you will take advance of this, not just copy and paste.

you just forgot to put inputs (filling array values) in your., rest of fine. See below is your code in which I just added array value input statement.

String [][]array2D = new String[5][10];

for(int r=0; r<array2D.length; r++)
{
    for(int b=0; b<array2D[r].length; b++)
    {
        array2d[r][b]=String.values(r);  
        System.out.print(array2D[r][b]);    
    }
    System.out.println();
}

System.out.println("Prepared By: Mark Vincent D. Yap");

}
