Re-hi

now I'm trying to compile Mark R Besonen piece of code allowing to
create folders using the macro language. Unfortunately, I get an
exception error when I try to compile this :

/** START "MakeDirectory_.java" code ** note that "mkdirs" (vs. "mkdir")
makes ** all intermediate parent directories ** even if they don't yet
exist */ import ij.*; import ij.plugin.*; import java.io.*; public class
MakeDirectory_ implements PlugIn { String DirToMake =
Macro.getOptions(); public void run(String arg) { File newDir = new
File(DirToMake); newDir.mkdirs(); } } /** END "MakeDirectory_.java" code */



with "Compile and Run" command.
The error is :

 java.lang.NullPointerException
 at java.io.File.<init>(File.java:194)
 at MakeDirectory_.run(MakeDirectory_.java:13)
 at ij.IJ.runUserPlugIn(Unknown Source)
 at ij.ImageJ.runUserPlugIn(Unknown Source)
 at ij.plugin.PlugInExecuter.run(Unknown Source)
 at java.lang.Thread.run(Thread.java:595)

I think I can't get to use the java.io class but I don't even know how
to add it to ImageJ so it can use it.

Any hint ?
