Java - creating new file, how do I specify the directory with a method?

Question

I want to write a file to a directory by doing this:

public void writefile(){

    try{

        Writer output = null;

        File file = new File("C:\\results\\results.txt");

        output = new BufferedWriter(new FileWriter(file));

        for(int i=0; i<100; i++){

           //CODE TO FETCH RESULTS AND WRITE FILE

        }

        output.close();

        System.out.println("File has been written");

    }catch(Exception e){

        System.out.println("Could not create file");

    }

How do I go on specifying the directory, if the directory is set in a method? A method called getCacheDirectory() for example. Assuming that all necessary imports etc have been done.

Answer 1

You mean just

  File file = new File(getCacheDirectory() + "\\results.txt");

That would be right  if getCacheDirectory() returned the path as a String; if it returned a File, then there is a different constructor for that:

  File file = new File(getCacheDirectory(), "results.txt");
