Question

Complete the Java program below so that it reads the text file dogNames.txt and writes its contents to another text file, "doggoneData.txt".

The file dogNames.txt contains just the single word "Tippy", so the output in "doggoneData.txt" should simply look like this:

Tippy

Your task is to complete the code below by using the variable name along with the appropriate Scanner and PrintWritermethods.

  String name;
  Scanner inputFile = new Scanner(new FileReader("dogNames.txt"));   
  PrintWriter outputFile = new PrintWriter("doggoneData.txt");

  inputFile.close();
  outputFile.close();
