    Default Writing output file

    I made a OneTimePad program and want to output the encrypted message to a text file from a string. I want to keep a running log of the output so it stores the string again after each iteration of the program.

    Just looking for a little push in the right direction as to what I should be doing.

    You basically just want to write a string to a text file?

    Have a look at the Java I/O API. It talks about files, paths, input/output, and so on. It's a great place to start, at the very least.

    I use printWriter to write something to a .txt file.
    First I make a file, and later I let the program write things into the file

    Java Code:
     
    File output = new File("File1.txt");
    PrintWriter output1 = new PrintWriter("File1.txt");
    Java Code:
     
    output1.println("Text here that needs to the file1");
    output1.flush();
    Maybe this helps?
