    Default writing text to file

    I have a quick question about writing text to a file. Why can't I just append the variable long to the file? Is there some restriction on what I can or cannot append to a file? If i just do w.write(estimateTime); the code will not compile. :confused:

    Java Code:
    //append execution time to file
    				BufferedWriter w = new BufferedWriter(new FileWriter("DESdata2.txt", true));
    				w.write(estimateTime+"\n");  //estimateTime is a variable of type long
    				w.close();

    Have you read this?

    look for write() method and see what should be the right parameter to use.....

            w.newLine();
