Paint????

[seanfmglobal]

Hey guys its me again. So I'm having an issue.

package pr1;

import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;

import javax.swing.JFrame;
import javax.swing.JPanel;

public class SemiPongPanel extends JPanel { // start of class
	public static void main(String[] args) { // start of main class

		JFrame frame1 = new JFrame("SemiPong"); // new jframe called frame1
		frame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); // default close
																// jframe on
																// exit

		JPanel panel1 = new JPanel(); // New Jpanel
		frame1.getContentPane().add(panel1); // Add panel1 to frame1
		panel1.setPreferredSize(new Dimension(600, 400)); // size of panel
		frame1.pack(); // Packs the panel size into the frame
		frame1.setVisible(true); // Make frame visible
		
		Ball singleBall = new Ball(30, 40, 10, Color.RED);
		
		
		
	//	@Override
	//	public void paint(Graphics g){
			
	//	}
		
		
	}
}

when placing

 public void paint(Graphics g)

I get an error that states. Void is an invalid type for the variable paint. But in my other program......

package balls;



import java.awt.Color;

import java.awt.Graphics;

import java.awt.Rectangle;

import java.util.Random;



import javax.swing.JApplet;







// Chantae M. Ross

@SuppressWarnings("serial")						// This got rid of a weird error i have never seen....

public class BallsApplet extends JApplet {

	//private Ball ball;

	private Ball[] testBall;

	private static Physics physics;



	

	

	public void init() {

		super.setSize(400, 500);

		//ball = new Ball(30, 30, 10, Color.green);

		physics = new Physics(this, this, 10);

		//physics.addBall(ball);

		testBall = new Ball[20];

		for (int index = 0; index < testBall.length; index++) {

			testBall[index] = makeRandomBall();

			physics.addBall(testBall[index]);

		}

	}



	@Override

	public void paint(Graphics g) {



		int redBalls = 0;

		int greenBalls = 0;

		Rectangle bounds = getBounds();

		g.setColor(Color.lightGray);

		g.fillRect(0, 0, bounds.width, bounds.height);

		//ball.draw(g);

		for (int index = 0; index < testBall.length; index++) {

			testBall[index].draw(g);

			if (testBall[index].getColor().equals(Color.red))

				redBalls++;

			else

				greenBalls++;

		}

		g.setColor(Color.BLACK);

		g.drawString("Chantae M. Ross", 10, 15);

		g.drawString("RedBalls: " + redBalls, 10, 30);

		g.drawString("Green Balls: " + greenBalls, 10, 45);

		if (redBalls == 20)

			physics.stopIt();

	}



	

	

	private int randomRange(int low, int high) {

		Random rand = new Random();



		int range = high - low;



		









		int number = low + rand.nextInt(range);

		return number;

	}



	private Ball makeRandomBall() { // What the hell is going on here???

		// randomBalls = new Ball(randomRange(20, 200), randomRange(20, 200),

		// randomRange(2, 10), Color.GREEN);

		// return randomBalls;

		Ball randomBalls = new Ball(randomRange(20, 200), randomRange(20, 200),

				randomRange(2, 10), Color.GREEN);



		randomBalls.setVelocityX(randomRange(-40, 40));

		randomBalls.setVelocityY(randomRange(-40, 40));



		// for (int index = 0; index < randomBalls.length; index++)

		return randomBalls;



	}



	/*

	 * private Ball fBall1;

	 * 

	 * @Override public void init() { super.setSize(400, 500);

	 * 

	 * fBall1 = new Ball(30, 30, 10, Color.GREEN); }

	 * 

	 * @Override public void paint(Graphics g) { fBall1.draw(g); } }

	 */



}

It works perfectly fine????

I've attached a screenshot of the error also just to clear up any confusion.

refer the reply of Fubarable in the thread "an error in paint method"

[seanfmglobal]

Entering super.paint(g), or paintComponent, etc doesn't work. Are you talking about the post that he is stating, the user is drawing directly to the JFrame??

[seanfmglobal]

Ok I got it, I had to declare the paint method outside the main method.
