Question

I’m making a program that will output lines to a text file. I don’t wish to overwrite the file, but that is what my current code does. I just want to go down the number of lines that are already there and write hello. Here is my code:

FileWriter fileWriter = new FileWriter(fileLocation, false);
BufferedWriter bufferedWriter = new BufferedWriter(fileWriter);

while(numberOfLines > compareToNumOfLines) {
    bufferedWriter.newLine();
    compareToNumOfLines++;
}

bufferedWriter.write("hello");
bufferedWriter.close();

Unfortunately, this just creates spaces where the text used to be. What am I doing wrong?

Change

FileWriter fileWriter = new FileWriter(fileLocation, false);

to

FileWriter fileWriter = new FileWriter(fileLocation, true);

As explained in the documentation, the second argument is a boolean that specify if you want to append the text or overwrite it.
