    Default Appending to a file to write to

    Hi everyone, I am new to input/output streaming, and I just want to know how to append to a file.

    Here is my code:

    Java Code:
    s = "this is my text"
    
    public static void main(String[] args) throws IOException {
    		         
    	PrintWriter outputStream = null;
    
    		         try {
    		           
    		             outputStream = new PrintWriter(new FileWriter("output.txt"));
    
    		                 outputStream.println(s);
    		         } finally {
    
    		             if (outputStream != null) {
    		                 outputStream.close();
    		             }
    		    }
    		}

    It does write to the output, but when I change the value of s and rerun the program, it just erases what was there before and writes on top of it. Is there a separate command for appending to a file and will it start on a new line?

    also, how would I indicate the path, right now it just puts it in my project folder.

    Thanks

    The FileWriter class has more than one constructor!

    Alright, that was perfect and solved my one problem.

    Now I'm just curious how to change the path of output.txt

    What I'm alluding to is that you can use the constructor that takes a File object. Create the File object with the required path.
