    How to print out the position of 2 dimension arrays?

    there are 2 dimension arrays, how can print out the position of value than 4?

    for example

    0 2 3 2 2 2
    0 1 1 2 5 3
    1 2 3 3 2 1

    print out:
    The pos is ( 4,1).

    You mean something like this?
    Code:
    for (int y=0; y<3; y++)
    {
        for(int x=0; x<6; x++)
            System.out.print(array[x][y]+" ");
        System.out.println();
    }

    Well you can just alter Phaelax's example. Put an if statement in there so you can check if the number in the current location is greater than 4.

    Phaelax's example loops through the entire array. If you replace his print statement with something like
    Code:
    if(array[x][y]>4)
    {
        System.out.println("(" + y + "," + x + ")");
    }
