      FileWriter myWriter = new FileWriter("filename.txt");
      myWriter.write("Files in Java might be tricky, but it is fun enough!");
      myWriter.close();
      System.out.println("Successfully wrote to the file.");
    } catch (IOException e) {
      System.out.println("An error occurred.");

public static void main(String[] args) {
try {
// Creating an object of a file
File myObj = new File("D:FileHandlingNewFilef1.txt"); 
if (myObj.createNewFile()) {
System.out.println("File created: " + myObj.getName());

}
} catch (IOException e) {
