Once you're happy with your game, you'll want to export it as a JAR file. In Eclipse, you can do this by right-clicking on your project and selecting "Export". Choose "Java" > "Runnable JAR file" and follow the prompts to create a JAR file.
Timer timer = new Timer(16, new ActionListener() public void actionPerformed(ActionEvent e) updateGame(); repaint(); ); timer.start(); java game jar 320x240 top
public class JavaGame extends JFrame private int ballX = 100; private int ballY = 100; private int ballSpeedX = 2; private int ballSpeedY = 2; Once you're happy with your game, you'll want
import javax.swing.*; import java.awt.*; Timer timer = new Timer(16, new ActionListener() public
public class JavaGame extends JFrame public JavaGame() setTitle("My Java Game"); setSize(320, 240); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setVisible(true);
Now that you have a game window, you can start adding game logic. This might include things like user input, graphics rendering, and game mechanics. For a simple game, you might use the java.awt.Graphics class to draw shapes and images on the screen.
Finally, you can test your JAR file by running it from the command line. Navigate to the directory where you saved the JAR file and type java -jar JavaGame.jar . Your game should launch in a window with a resolution of 320x240.
