Task 1: Class CreateTextFile uses a Formatter to output formatted Strings, using the same formatting capabilities as method System.out.printf. A Formatter object can output to various locations, such as to a command window or to a file. Modify class CreateTextFile so it will output to a different file. Screen shot your program, the command window (which shows user input), and the output of your text file.
