Question
Speed Reader (Adapted from) This project requires you to create a program that takes two inputs: A string of any length. A number of words per minute. Your program will take the string, break it up into individual words, and display it one word at a time at the desired rate. For instance, "Hello World!" at 500 words per minute would display "Hello" for 3/25^ths of a second and then "World!" for 3/25^ths of a second. You'll be surprised to discover that you can read words that are displayed quite quickly! This project has the following deliverable levels: C: Your project prints words to the command line at the desired rate. While it is printing words, those words are the ONLY thing in the command line. B: Your project prints words to another window besides the command line. A: Your project has a graphical interface that will let a user input a string, select a rate, and press a button to display the words of that string at the desired rate.Explanation / Answer
This is platform independent code, works well in most terminals. Most part of the code is auto generated NetBeans code for GUI. The vital part is copied and commented below the main code
