Question

Need help creating a bingo card and bingo in java using a 2d array that is 5x5. This is what I have so far for the bingo card java, I havnt done the game java yet cause I cant seem to get the isBingo method working for checking for bingo. This I what I have so far for the bingo card.

class BingoCard{
private int[][] card;
private boolean [][] mark;

public BingoCard(){
card = new int[5][5];
for(int r = 0; r < 5; r++){
for(int c = 0; c < 5; c++){
card[r][c] = (int)((Math.random()*100)/2 + 1);
}
}
mark = new boolean[5][5];
for(int r = 0; r < 5; r++){
for(int c = 0; c < 5; c++){
mark[r][c] = false;
}
}
}


public void display(){
for(int r = 0; r < 5; r++){
for(int c = 0; c < 5; c++){
System.out.print(card[r][c] + " ");
}
System.out.println("");
}
for(int r = 0; r < 5; r++){
for(int c = 0; c < 5; c++){
System.out.print(mark[r][c] + " ");
}
System.out.println("");
}
}


public void mark(int number){
for(int r = 0; r < 5; r++){
for(int c = 0; c < 5; c++){
if(card[r][c] == number){
mark[r][c] = true;
}
}
}
}


public boolean isBingo(){
boolean bingo = false;
int count1, count2;
count1 = 0;
count2 = 0;
for(int i = 0; i < mark.length; i++){
for(int j = 0; j < mark.length; j++){
if(mark[i][0] == true){
count1++;
}
if(mark[0][j] == true){
count2++;
}
}
}
if(count1 == 5){
bingo = true;
}
if(count2 == 5){
bingo = true;
}
return bingo;
}





}
