Newbie question, String index out of range

[magnus2]

In an applet I got this error-message in a Java-s system window. What could be the problem? Grateful for comments.

You are using the 'substring' command somewhere. You are probably doing something like:

myString.substring(0, myString.indexOf("*"));

...or something like that and your string doesn't contain the (for example) asterisk, so you are effectively asking it for:

myString.substring(0, -1);

...which would lead to the out-of-bounds error.

Check it out. Post all your substring commands if this doesn't help.

Good luck.
