Question

我如何查看平局？我设法检查左右两个对角线以及水平和垂直。但我需要知道如何检查平局。我知道我需要检查所有按钮（在我的情况下按钮[6] [7]）。

//Checking the Diagonal_right win

for (int i  = 0; i < 6 ; i ++){
    for (int j  = 0; j < 7; j ++){
        if ((i+1)==6 || (i+2)==6 || (i+3)==6){
            break;
        }

        if(imageName[i][j] == singleimageName && 
                imageName[i+1][j-1] == singleimageName &&
                imageName[i+2][j-2] == singleimageName &&
                imageName[i+3][j-3] == singleimageName){
            JOptionPane.showMessageDialog(null,""
                    + "You Have Won! \n"
                    + "Player Using " + singleimageName +
                    " Connected 4");
            clearGrid();

        }
    }
}

//Checking the Horizontal win

for (int i  = 0; i < 6; i ++){
    for (int j  = 0; j < 7; j ++){
        if ((i+1)==6 || (i+2)==6 || (i+3)==6){
            break;
        }

        if(imageName[i][j] == singleimageName && 
                imageName[i][j+1] == singleimageName &&
                imageName[i][j+2] == singleimageName &&
                imageName[i][j+3] == singleimageName) {
            JOptionPane.showMessageDialog(null,""
                    + "You Have Won! \n"
                    + "Player Using " + singleimageName +
                    "  Connected 4");
            clearGrid();

        }
    }
}

//Checking the Vertical win

for (int i  = 0; i < 6; i ++){
    for (int j  = 0; j < 7; j ++){
        if ((i+1)==6 || (i+2)==6 || (i+3)==6){
            break;
        }

        if(imageName[i][j] == singleimageName && 
                imageName[i+1][j] == singleimageName &&
                imageName[i+2][j] == singleimageName &&
                imageName[i+3][j] == singleimageName) {
            JOptionPane.showMessageDialog(null,""
                    + "You Have Won! \n"
                    + "Player Using " + singleimageName +
                    "  Connected 4");
            clearGrid();

        }
    }
}

// Check for a draw
boolean draw = true;
for (int i  = 0; i < 6; i ++) {
    for (int j = 0; j < 7; j ++) {
        if (imageName[i][j].getIcon() == null) {
            draw = false;
        }

if (draw) {
    JOptionPane.showMessageDialog(null, "It's a draw!");
    clearGrid();
}
