Java File - Open A File And Write To It [closed]

Question

I know we are supposed to add a snipit of code to our questions, but I am seriously dumbfounded and can't wrap my head or find any examples to follow from.

Basically I want to open file C:\A.txt , which already has contents in it, and write a string at the end. Basically like this.

File A.txt contains:

John
Bob
Larry

I want to open it and write Sue at the end so the file now contains:

John
Bob
Larry
Sue

Sorry for no code example, my brain is dead this morning....

Please Search Google given to the world by Larry Page and Sergey Brin.

BufferedWriter out = null;

try {
    FileWriter fstream = new FileWriter("out.txt", true); //true tells to append data.
    out = new BufferedWriter(fstream);
    out.write("\nsue");
}

catch (IOException e) {
    System.err.println("Error: " + e.getMessage());
}

finally {
    if(out != null) {
        out.close();
    }
}
