Writing to an already existing file using FileWriter Java

Question

Is there anyway I can write to an already existing file using Filewriter

For example when the user clicks a submit button:

FileWriter writer = new Fi         


        

Answer 1

Yeah. Use the constructor like this:

FileWriter writer = new FileWriter("myfile.csv",true);

Answer 2

FileWriter

public FileWriter(File file,
                  boolean append)
           throws IOException

Constructs a FileWriter object given a File object. If the second argument is true, then bytes will be written to the end of the file rather than the beginning.
