Index out of bounds exception

807589Sep 21 2008 — edited Sep 21 2008

Hey everyone I have a major problem with an Index out of bounds exception in execution time....

It's probably because I have sets of defining coordinates X and Y, first one defining X and the others defining Y

Let me show you what I've written:

private int xPos;
private int yPos;
private String note;
private void gPanel1MouseClicked(java.awt.event.MouseEvent evt) {//GEN-FIRST:event_gPanel1MouseClicked

xPos = evt.getX();
yPos = evt.getY();

if (xPos >= 100 && xPos <= 228 )
{xPos = 158;
gPanel1.setXCoordinates(xPos);
}
else if (xPos >= 242 && xPos <= 346 )
{xPos = 290;
gPanel1.setXCoordinates(xPos);
}
else if (xPos >= 365 && xPos <= 462 )
{ xPos = 406;
gPanel1.setXCoordinates(xPos);
}
else if (xPos >= 481 && xPos <= 571 )
{xPos = 518;
gPanel1.setXCoordinates(xPos);
}
else if (xPos >= 590 && xPos <= 667 )
{ xPos = 621;
gPanel1.setXCoordinates(xPos);
}
else if (xPos >= 694 && xPos <= 771 )
{xPos = 725;
gPanel1.setXCoordinates(xPos);
}
else if (xPos >= 788 && xPos <= 864 )
{ xPos = 819;
gPanel1.setXCoordinates(xPos);
}

//Set 1st string distances
if (yPos >= 15 && yPos <= 39 && xPos >= 100 && xPos <= 228)
{yPos = 22;
xPos = 158;
gPanel1.setXCoordinates(xPos);
gPanel1.setYCoordinates(yPos);
note = "F";
}
else if(yPos >= 15 && yPos <= 39 && xPos >= 242 && xPos <= 346)
{yPos = 20;
gPanel1.setYCoordinates(yPos);
note = "F#";
}
else if(yPos >= 15 && yPos <= 39 && xPos >= 365 && xPos <= 462)
{yPos = 18;
gPanel1.setYCoordinates(yPos);

}

}

JOptionPane.showMessageDialog(null, "Invalid position. Try again towards the center of the fret","Error",JOptionPane.ERROR_MESSAGE);

//Paint the dot
gPanel1.paint( gPanel1.getGraphics());

System.out.println(note);
}

What it does is specifying where to draw when the mouse is clicked and where it should print error...

The thing is that I believe that something in the way this is written causes the exception I mentioned...

If you see something wrong please let me know...

Thanks in advance,

Akis
