Bingo Jgrasp programming help!

[Strawberrypie]

I'm using Jgrasp to make a Bingo Game, but I don't know how to generate a card for each player or call out a random number like "B7". Can you guys help me out?

Here's my Code:

import java.util.Scanner;

public class BingoGame {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String [][] letters = new String[1][5];
letters[0][0] = "B";
letters[0][1] = "I";
letters[0][2] = "N";
letters[0][3] = "G";
letters[0][4] = "0";
System.out.print("Enter the number of players: ");
int players = input.nextInt();
int [][][] cards = new int [players][5][5];
for (int b = 0; b < cards[0].length; b++) {
 cards[player][b][0] = (int)(Math.random() * 15) + 1;
for (int i = 0; i < cards[0].length; i++) {
 cards[players][i][1] = (int)(Math.random() * 30) + 1;
for (int n = 0; n < cards[0].length; n++) {
 cards[players][n][2] = (int)(Math.random() * 45) + 1;
for (int g = 0; g < cards[0].length; g++) {
 cards[players][g][3] = (int)(Math.random() * 60) + 1;
for (int o = 0; o < cards[0].length; o++) {
 cards[players][o][4] = (int)(Math.random() * 75) + 1;
}
}
}
}
}
System.out.println("Player " + players);
System.out.println(letters[0][0] + " " + letters[0][1] + " " + letters[0][2] + " " + letters[0][3] + " " + letters[0][4]);
System.out.println(cards[players][5][5]);        
}
}

No no no! It's not for the forums, it's my homework! Come on, people help me out quick!

You have a few problems in there. But I guess that you know what you want it to do, so some exact help with that would be good.

so the user is asked for the number of players... they enter the number.

then what happens?

----

I've coded the following. It assigns each player 5 numbers. Using Math.random(). What you need to look at is your Array Structure. It's seriously out of whack. Why are you doing you 'BINGO' declaration like that? Firstly, they're Chars. So use a Char Array. Secondly, declare the array when initialising it.

Let me know if you need any help with it.

And you're using Java not Jgrasp!

import java.util.Scanner;

public class BingoGame {
	public static void main(String[] args) {
		Scanner input = new Scanner(System.in);
		char letters[] = {'B', 'I', 'N', 'G', 'O'};
		System.out.print("Enter the number of players: ");
		int players = input.nextInt();
		int [][] cards = new int [players][5];
		for(int i = 0; i < cards.length; i++)
			for(int x = 0; x < cards.length; x++)
				cards[x] = (int)(Math.random() * 30);
		for(int i = 0; i < players; i++){
			System.out.println("Player " + (i + 1) + " Numbers");
			printNums(cards);
		}
	}
	public static void printNums(int [] x){
		for(int y = 0; y < x.length; y++)
			System.out.print(x[y] + " ");
		System.out.println();
	}
}
