public FileWriter(File file, boolean append) throws IOException

You can open the FileWriter in append mode by passing Matthew CrumleyMatthew Crumley
true as the second parameter:

You may pass true as second parameter to the constructor of FileWriter to instruct the writer to append the data instead of rewriting the file.
For example,
fout = new FileWriter( 'Distribution_' + Double.toString(lowerBound) + '' + Double.toString(_highBound) + '.txt',true);
Hope this would solve your problem.
