Question

I am currently using an external library function that returns a File object. This works fine for making the file at a default location, but to accommodate concurrent users, I need to have the file be in a specific folder. Without being able to alter the function that makes the file, is there a File function that let’s me specify where it will go to?

You can use the renameTo(File destination) in the File API to rename the file storing it in another abstract path.

ex:

import java.io.File;

public class MainClass {

  public static void main(String args[]) {

    try {

      File oldFile = new File("/usr/bin/temp/");

      File newFile = new File("/usr/bin/hunter/temp");

      boolean result = oldFile.renameTo(newFile);

      System.out.println(result);
    } 
    catch (Exception e) 
    {
      e.printStackTrace();
    }

Also note that the API says that this is not always guaranteed to succeed, so you need to check the return value of the method call every time you use this method.
