TypingTimer.java

This assignment will help you work with the LONG data type. There are not a whole lot of applications where you need to use 'long' unless you work with large numbers a lot (like student id numbers).

What we want to do is to make a program that tests how fast the user can type in a set of keystrokes.
System.currentTimeMillis(); is a system function that tells how many milliseconds have elapsed since time began (ie. 1 January 1970).
There are 5 different sets of keys to type, each with a description to help the user know which set to type.

TOP ROW = qwertyuiop
MIDDLE ROW = asdfghjkl;
BOTTOM ROW = zxcvbnm,
LEFT SIDE = qwerasdfzxcv
RIGHT SIDE = uiophjlbnm,

• go through each of these sets, but do it in a random order
• display the description as well as the letters to type
  Make it easy for the user to see right away what he/she has to type.
• start the time somehow (press to start)
• the user now types the correct keys and presses
• record the time elapsed
• verify that the text typed matches the required keys
• store the resulting time for this set, and then go on to the next one

We will be using this program later on when we start doing file I/O.

NOTE: if you're reading text from Scanner, always use .nextLine() instead of .next() — unless you have a specific reason not to.
