String.split() missing in leJOS?

[werner291]

Hello, I recently had some strange behavior from the nxj compiler. After de-compiling the classes.jar, I found out why.

In the official JDK, the String class provides the "String[] split(String)" and the "String[] split(String, int)" methods.
These seem to be missing from "String.class" in classes.jar.

Does the nxj compiler use the JDK or classes.jar?

Hi,
For code running on the NXT leJOS uses its own set of class files located in classes.jar. There is no need to decompile the file we supply all of he source files as part of the standard install, or you can browse them on line... So for instance the String class is here...

You can also see the API docs for the NXT here:

I suspect that reason split is missing is the use of regular expressions. I don't think we have an implementation of those (which can be relatively large) for the NXT...

Exactly. The argument of String.split() is a regular expression. And we don't have an implementation of java.util.regexp for the NXT.

Ok, I'll see if I can find some other workaround in that case.

Don't know if you've solved it but you can use substring instead of split

Yes, I have solved it. I just wrote a small function that cut up the string at every space character.
