Question

I have the following code:

public boolean prontoParaJogar() throws RemoteException {
    int i;
    int j;
    if (this.jogadores==2) {
        this.jogando=1;
        for (i=0;i<3;i++)
            for(j=0;j<3;j++) {
                this.tabuleiro[i][j]=0;
            }

        for (i=0;i<3;i++) {
            System.out.println("Linha "+i+": ");
            System.out.print(this.tabuleiro[i][0]+' ');
            System.out.print(this.tabuleiro[i][1]+' ');
            System.out.print(this.tabuleiro[i][2]);
            System.out.println("");
        }


        return true;
    } else {
        return false;
    }
}

it is printing the following exit:

Linha 0:
32320
Linha 1: 
32320
Linha 2: 
32320
Linha 0: 
32320
Linha 1: 
32320
Linha 2: 
32320

This is not what I expected. It should be the following output:

Linha 0:
0 0 0
Linha 1:
0 0 0
Linha 2:
0 0 0

I can’t figure out why its not running as expected.

Answer 1

this.tabuleiro[i][0]+' '

' ' is the character for whitespace, which has the ascii value 32. Single quotes denote a char value not a String

this.tabuleiro[i][0]+" "

will concatenate a space.
