Estou codificando um programa que é um jogo de memória 4x4. Dentro destas 16 caixas haverá um par de números inteiros de 0 a 7. Eu tenho tudo isso já randomizado e codificado corretamente. Agora eu estou tentando descobrir como emparelhar as cores com os inteiros correspondentes cada vez que o mouse clica sobre a caixa.

Aqui a maior parte do código. Eu sei que a lógica para este jogo ainda não começou, mas estou mais focado no método displayHit e no método setColor agora. Apenas postando o código inteiro porque talvez eu tenha bagunçado em outro lugar.

<code>/*Sets the background of your memory board to black*/
public void init() 
{
    setSize(400,400);
    setBackground(Color.BLACK);
    buildBoard(4);

}   
/*This is main in java applets
    You may need to add (not change) a couple things in this method
 */
public void paint(Graphics canvas)
{
    if(firstRun) //for the first run we need to build our random board
    {

        print2DArray(board);
        buildBoard(4);
        firstRun = false;
    } 
    else // once our board is built we will display the game
    {
        displayGame(canvas);
        if (mouseClicked) // if the mouse has been clicked
        {
            displayHit(canvas);//find which box the user clicked
            mouseClicked = false;
        }
    }
}

/*

public boolean mouseDown(Event e, int x, int y )
