How can I get a filename without the file extension?

Question

I using a JFileChooser to select and read a file. Now I want to get the filename without the file extension
JFileChooser j = new JFileChooser;
String file = j.getSelectedFile.getName();
At the moment I get this result "file.dat". I need only the filename.....
Thank you

It's quite that.
Here is the code to do that (and the method to get only the extension):
     public String getFileName(String text) {
          int ind = text.lastIndexOf(".");
          if(0<ind && ind<(text.length()-1)) {
               return text.substring(0, ind);
          return(null);
     public String getFileExtension(String text) {
          int ind = text.lastIndexOf(".");
          if(0<ind && ind<(text.length()-1)) {
               return text.substring(ind+1).toLowerCase();
          return(null);
     }(I used 0<ind instead of ind>0 because with the code formatting there is a bug with > )
I hope this helps,
