Illegal Character error: '\u200b'

Question

I'm making an Asteroid Field for an Asteroid Game in my Object Oriented Programming class and I am receiving an illegal character error: '\u200b'. The issue seems to be happening on line 12. (The line between import java.awt.Point; and public class Asteroid extends PolyBlob)

/*  * University of Central Florida  * COP3330 - Spring 2016  * Author: Aundray Ortiz  */ package asteroidfield;  import java.util.Random; import blobzx.PolyBlob; import blobzx.BlobUtils; import java.awt.Point; ​ public class Asteroid extends PolyBlob {     private static final Random random = new Random();      public Asteroid(int a, int b, double c)     {         super(-100,-100,c);         int sides = 5 + random.nextInt(5);         int[] x = new int[sides];         int[] y = new int[sides];         int going = 0;         double direct = 0;         double region = (Math.PI * 2)/sides;         for(int num = 0; num<sides;num++)         {             going = 5 + random.nextInt(16);             direct = (num * region) + (Math.random() * region);             Point p = BlobUtils.rotatePoint(going, direct);             x[num] = p.x;             y[num] = p.y;         }          setPolygon(x, y);         setRate(c);         setDelta(a,b);     } } 

Answer 1

\u200b is a "zero-width-space" in Unicode.

You should delete line 12 (the blank line), save the file, re-add the blank line and save again. using a simple text editor.

If that doesn't fix it delete lines 11 and 13 as well and recreate them.

Answer 2

I think the point here is to not retype the copied code. So with that in mind:

Steps:

1- Ctrl + r Replace (tick Regex checkbox)

2- paste the character code: \u200b

3- replace all with nothing

Done!
