Thread: 65535 bytes java limit

Good day everyone!

First of all, I'm so new in programming, but I'm willing to learn.
Here's my problem..

I draw an image, a cartoon characters. I use java language. Yeah, I know how to do that but my problem is I'm not able to finish it because I'm exceeding the 65535 bytes java limit because I have a lot of coordinates.
This image that I'm drawing and my code is on the attachment (unfinished because of error )

I already made a class that extends JComponent even though it's not needed just because I want to have a space for my coordinates

Can you help me solve my problem on where to put the other coordinates?
Actually that is my main problem, where to put the coordinates


Thanks in advance

@KevinWorkman

I don't know if I can make this clear but I will try

I am drawing an image. In order to do that,
I use

g.fillPolygon(a, b, a.length)

so that means I need to declare first an array of coordinates(which is a[] for x coordinates, and b[] for y coordinates) to draw one polygon or shape.

If you saw the image, that has a lot of shape and I need a lot of coordinates for it(the drawing) to be precise. But I think java has a limit of 65535 bytes per method.

so I don't know where to put my other array or coordinates.




@Norm

How can I do that?
Did you mean I can declare a variable wriiten in a text file? and read it in a program?


Sorry, I'm so new to this

Thanks for helping guys

Use multiple polygons rather than one to draw the whole image.

@GregBrannon

That's what I'm doing


@Norm

Can you give me a sample code for that please? If that's okay with you



Thank you so much for the help guys

I did what you told me but there's a problem.

I can only do that on one array(xArray) and not on yArray

Here's my code

public void paint(Graphics g){
	 Scanner sc = null;
	 int i=0;
	 try
	 {
	 sc = new Scanner(new FileInputStream("C:\\x.txt"));
	 sc.useDelimiter(",");
	 }
	 catch(Exception e)
	 {
	 System.out.println("file not found!");
	 }
	 int[] xArray = new int[4];
 
	 while (sc.hasNextInt( )){
			xArray[i++] = sc.nextInt( );
			}
		 sc.close( );
 
	 int[] yArray = {58,58,122,122};
 
		g.setColor(Color.BLACK);
		g.fillPolygon(xArray, yArray, xArray.length);
}

I can draw using that code.


But if I do this

public void paint(Graphics g){
	 Scanner sc = null;
	 Scanner sc1 = null;
	 int i=0;
	 try
	 {
	 sc = new Scanner(new FileInputStream("C:\\x.txt"));
	 sc.useDelimiter(",");
	 sc1 = new Scanner(new FileInputStream("C:\\y.txt"));
	 sc1.useDelimiter(",");
	 }
	 catch(Exception e)
	 {
	 System.out.println("file not found!");
	 }
	 int[] xArray = new int[4];
 
	 while (sc.hasNextInt( )){
			xArray[i++] = sc.nextInt( );
			}
		 sc.close( );
 
	 int[] yArray = new int[4];
 
	 while (sc1.hasNextInt( )){
			yArray[i++] = sc1.nextInt( );
			}
		 sc1.close( );
 
		g.setColor(Color.BLACK);
		g.fillPolygon(xArray, yArray, xArray.length);
}

I got runtime error


Can you tell me how can I add more array using that technique?



Thanks again.

Thank you so much for the big help sir

I already got it. Hopefully I don't get the 65535 byte error thing again because I started all over again. Let's see if it occurs again



By the way, why did you say this?

Is that important? I mean, my code worked already.

Can you tell me why?



Thanks again sir.

So where should I put the codes? In the main method?
If yes, how can I use it in paint method?

I'm so sorry. I'm so new at this


Thank you.
