writing results of recursion into file

[sara12345]

hello
I have recursive function and I want to write the results of this recursive function into file without deleting the old content of file but the problem I have is that when I call recursive function it overwrites results on the content of file
this is the code

static void Reordering_solution(File reordering){
	 try {
	FileWriter writer_rodering_out = new FileWriter(reordering);
	///////////////////////////////////////////////////
          function
        ////////////////////////////////////////////
      writing into file
    /////////////////////////////////////////////
   Reordering_solution( reordering)
}

any suggestion how to fix this problem

Don't (re)open the output file every time your recursive method runs but pass it an OutputStream as a parameter. Close the stream outside of that method when it has finished (and open it before you call it for the first time).

kind regards,
