Thanks! &nbsp; 
 
that wasn't quite what i needed, but using the plus made my realize that by putting a * after everything i do is going to match anything. This is what i used instead - &nbsp;&quot;([0-9]+\\.*)+&quot;

Your pattern will of course match &quot;1234567890&quot; but maybe that's no bad thing ...

OUTPUT: 
 
true

So ... it is matching the pattern when i use match(), however the split is splitting as if its delimeter is &quot;&quot;, and the matcher isnt finding the pattern at all ... &nbsp; 
 
Any suggestions?

weird java regex stuff

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
