Problem splitting a string

[sehudson]

I am trying to split up a filename into parts:

            String filename = file.getName();
            System.out.println("File: "+filename);
            String[] parts = filename.split(".");
            System.out.println(parts[0]);

My output is:

File: hello.txt

Then I get an indexoutOfBounds exception when trying to print out parts[0].

I even went so far as to iterate over each character in the filename string and keep a count of the "." instances, and it gives me back a 1 so I know it recognizes the period...not sure whats going on.

split uses a regex and in regex "." has special meaning. You'll want to escape that period:

String[] parts = filename.split("\\.");
