Filename seperately & Putting data from Hash Map to two different columns

Question

The following code produces the output as :
$ java getNamefile
File Name : reaper.txt
File Name : Testing
Is it possible to just get the file name "reaper" from it instead of reaper.txt
import java.io.*;
class getNamefile
     public static void main(String[] args)
          File f1 = new File("C:/javamyprograms/reaper.txt");
          File f2 = new File("C:/javamyprograms/Testing/");
          System.out.println("File Name : " + f1.getName());
          System.out.println("File Name : " + f2.getName());
}Secondly I am trying to put the values from a HashMap into ".xls"
PrintWriter out = new PrintWriter (new FileWriter("Unique_words_count" + file) + ".xls");
and out.write(key + " " + hm.get(key));
This put the values in the same columns. I want the results to be two different columns like
column1 column2
key1 value1
key2 value2
Please do advise. Thanks in advance.

Is it possible to just get the file name "reaper"from it instead of reaper.txtActually, I ran a test, and
     System.out.println(  "file name portion == " + ( f.getName().split( "\\." ) )[ 0 ] );works also:
This has the same effect as:
     String fileName = f.getName();
     String splitFileName[] = fileName.split( "\\." );
     System.out.println(  "file name portion == " + splitFileName[ 0 ] );Now that I think about it, the second form is more easily understood. There is really no reason to do it the first way. Just interesting to note that you can.
