Help with image display on JPanel
Hello guys! This is my first thread and my first time taking part in the world of forums. Anyway I started my intro to Java class at a local CC here and I would be lying if I said it has been on of the easiest computer science classes I have taken. Again anyway, I have a final project due where I need to create a game that contains an animation with sound. So I have a game in the taste of Price is Right where the user needs to guess the price of 1 of 3 prizes that are generated using the random method in java.util.Random. I have the logic down. It's where the animations comes in that I'm stuck. The user has 60 second to get the "price right". So in a JPanel I'm trying to cycle thru images of numbers (60 - 0) but I'm having trouble just trying to display one! I know that I need to create an array of String type for the file names and need a ActionListener with a Timer type to calculate when a second goes by and then use the repaint method to repaint it but I'm not sure what I am doing wrong. I tried using Javadocs but not much help there. Here's a copy of the code: (Any help would be grealty appriciated!!)
