How to store text file contents into an arrays and display them

I am trying to store the content of my text file into an arrays and display them in the console. I also want to find the empty space in the file and insert a game board there which I designed earlier.

Here is my text file content:

rfhrf
1
4

sdtgv
1
1

rfhrf
1
3

sdtgv
2
1

rfhrf
4
4

sdtgv
3
1

and here is what I have so far:

File text = new File("actions.txt");
try {
    Scanner scanner = new Scanner(text);

    while (scanner.hasNextLine()) {

    String line = scanner.nextLine();
    System.out.println(line);   
    Thread.sleep(5000);
    }

    scanner.close();
} catch (FileNotFoundException e) {
    e.printStackTrace();
} catch (InterruptedException e) {
    e.printStackTrace();
}

any help would be great.

I think you don't need to use Array. Just try the following! Hope it works!

File text = new File("actions.txt");
try {
    Scanner scanner = new Scanner(text);

    while (scanner.hasNextLine()) {
        String line = scanner.nextLine();
        if (line.isEmpty()) {
            System.out.println("This is Space!");
        } else {
            System.out.println(line);
        } 
        Thread.sleep(5000);
    }

    scanner.close();
} catch (FileNotFoundException e) {
    e.printStackTrace();
} catch (InterruptedException e) {
    e.printStackTrace();
}

What you could do is define a format by convention, alterating your file, to make it look like this:

rfhrf;1;4
sdtgv;1;1
...

and then for every read line, you can see the value and the position. Example:

File text = new File("actions.txt");
try {
    Scanner scanner = new Scanner(text);

    while (scanner.hasNextLine()) {

        String line = scanner.nextLine();
        String params = line.split(";");
        String value = params[0];
        int row = Integer.parseInt(params[1]);
        int col = Integer.parseInt(params[2]);

        myArray[row][col] = value;

    }

    scanner.close();
} catch (FileNotFoundException e) {
    e.printStackTrace();
}

That should help you, if I actually understood what you meant.

Do your own class that provides all your needs(like space counts,words) let's say MyClassContainer and then put all your MyClassContainer in a hashtable.It is quick and easy
