i am creating a snake game i am using a 2D array as my backframe. there is no syntax error. i am receiving a Exception in thread. this is where i think the error lies:
java.awt.EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
new SnakeGame().setVisible(true);
SnakeGame obj1;
obj1= new SnakeGame();
obj1.gameEngine();
}
or
case 908:
x9y8= new JLabel(icon);
break;
case 9:
x0y9= new JLabel(icon);
break;
i am using netbeans and creating the labels using the palette. therefore the labels are already created. the exception is:
run:
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

BUILD SUCCESSFUL (total time: 4 seconds)
what is the error and how should i rectify it? the error is supposed to be on line 775
int score=0;
int n=5,c=7;
ImageIcon image= new ImageIcon(getClass().getResource("1327691176237.jpg"));
ImageIcon image1= new ImageIcon(getClass().getResource("1327691176397.jpg"));
i have imported the image into the package and a default package was also created

The exception is happening on line 775 of your SnakeGame
class, inside the class constructor - it looks like you are trying to create an ImageIcon
object, passing in a null reference instead of some image data.
