Question

Speed Reader (Adapted from ht tp://nifty.stanford.edu/2015/posera-speed -reader/) 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 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

NOTE : All the deliverables are completed. And moreover, used Java language because the question was not language specific
