		// TODO Auto-generated method stub

		try {
			// file handle -> hold the path of the file
			File file = new File("c:\\newfile.txt");

			// file won't be created until, you call createNewFile()
			if (file.createNewFile()) {
				// running program for the first time, it would come here
				System.out.println("File created!");
			} else {
				// next time, would always come here as file is created.
				System.out.println("File already exists!");
			}

		} catch (IOException e) {
			e.printStackTrace();
