[ale] OT: java filereader question

[Denny Chambers]

First, what version of java are you using? (java -version)

If you using Sun/IBM/Blackdown versions 1.1 or later, then this should work:

String filename = (conditional ? "file1" : "file2");
FileReader fr = new FileReader(filename);

Now file1 and file2 should be a string representation of the relative or absolute path the files in question

FileReader has a constructor FileReader(String fileName)
