Random Digit Generator Help (Java)

I have written a code that is generating random numbers based on user input. For example, if the user says they want the program to generate 3 random digits for them, and they want it to do it 3 times, the output will look like this:

1 4 5

2 6 5

3 4 5

The code that I've written would display this as:

1

4

5

2

6

5

3

4

5

How do I make them display as 3 numbers wide? Here's my code:

 if (gameType == 3)

    //for loop to generate random numbers     
    for (int i = 1; i <=numGames; i = i + 1){

        for(int j = 1; j <= numGames * 3; j = j + 1 ){
            ranNums = randomGenerator.nextInt(9);

            //Print random numbers to user
            System.out.println(ranNums);
