This example shows how to create a directory on disc.
It also shows how to create multiple directories in case the ancestor directory
of the one at the bottom of the tree don't exist.

import java.io.File;

public class FileUtil {

  public void createDirectory(String dir) {

    File directory = new File(dir);

    //Alternative 1: All ancestor directories must exist.
    if (directory.mkdir()) {

      System.out.println("Success using alternative 1");

    }
    else {

      System.out.println("Failed using alternative 1, trying alternative 2");

      //Alternative 2: If ancestors doesn\'t exist, they will be created.
      if (directory.mkdirs()) {

        System.out.println("Success using alternative 2");

      }
      else {

        System.out.println("Failed using both alternative 1 and alternative 2");

      }
    }
  }

  public static void main(String[] args) {
    FileUtil fileutil = new FileUtil();
    fileutil.createDirectory("C:\\\\temp\\\\temp1\\\\temp2\\\\temp3");
  }
}
