Question

I know how to create a PrintWriter and am able to take strings from my gui and print it to a text file.

I want to be able to take the same program and print to the file adding text to the file instead of replacing everything already in the text file. How would I make it so that when more data is added to the text file, it is printed on a new line every time?

Any examples or resources would be awesome.

Answer 1

    try 
    {
    PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter("outfilename", true)));
    out.println("the text");
    out.close();
     } catch (IOException e) {
    }

The second parameter to the FileWriter constructor will tell it to append to the file (as opposed to clearing the file).

Using a BufferedWriter is recommended for an expensive writer (i.e. a FileWriter), and using a PrintWriter gives you access to println syntax that you’re probably used to from System.out.

But the BufferedWriter and PrintWriter wrappers are not strictly necessary.
