Any ideas on this code. l trying to change the background color of the container from one color to another each time the button is clicked, l used the if statement, it checks if the x is even then it chooses the background color to set based on the Boolean expression result, it seems as if the fired event is not recognizing the if statement so it keeps choosing one color yellow. Is there anything wrong with the if statement?
Please UseCodeTags (← click) when posting code as it makes it easier for people to read your code. I've added them for you this time.
Your problem is variable 'x' is local to the actionPerformed method and so every time you press the button a new 'x' is being used which is initialized to 0 and hence the same colour. I suggest you make the 'x' variable an instance variable rather than a local method variable, ie move it out of the method.

thank you it worked perfectly, it had slipped my mind that an applet can have attributes just like any other class.
