Rock, paper, scissors game Java applet

Question

I'm having problems with my java applet. I've made a Rock paper scissors game and i have 2 problems which I can't solve: 1. how to load the applet without the rock image on the left (players choice) 2. the score for player and computer does not reduce by 1 for every lost game

how to load the applet without the rock image on the left (players choice)

You need to have a fourth case for your myValue variable, when the player has not made a choice yet. Right now you only have three potential values, and the default is 0, which is why you see a rock image before you make a choice.

the score for player and computer does not reduce by 1 for every lost game

You're using ints where you should be using enums and booleans, which is making your code harder to understand. I'd highly recommend refactoring your code to use enums and booleans instead of ints.

Also, you're always calling every method from the paint() method. Don't do that. Instead, only call the functions that check for a winner when the player actually makes a choice, presumably from a button click.

Finally, you're also calling setLocation() inside your paint() method, which is a bad idea. You should only call setLocation() once, or better yet, use a layout manager.
