Java - how do I write a file to a specified directory

Question

I want to write a file results.txt to a specific directory on my machine (Z:\results to be precise). How do I go about specifying the directory to BufferedWriter/FileWriter?

Currently, it writes the file successfully but to the directory where my source code is located. Thanks

    public void writefile(){      try{         Writer output = null;         File file = new File("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");     } } 

Answer 1

You should use the secondary constructor for File to specify the directory in which it is to be symbolically created. This is important because the answers that say to create a file by prepending the directory name to original name, are not as system independent as this method.

Sample code:

String dirName = /* something to pull specified dir from input */;  String fileName = "test.txt"; File dir = new File (dirName); File actualFile = new File (dir, fileName);  /* rest is the same */ 

Hope it helps.
