For this lab you will write a Java program that plays a simple Guess The Word game. The program will prompt the user to enter the name of a file containing a list of words. These words mustbe stored in an ArrayList, and the program will not know how many words are in the file before it starts putting them in the list. When all of the words have been read from the file, the program randomly chooses one word from the list to be the target of the game. The user is then allowed to guess characters one at a time. The program checks to see if the user has previously guessed that character and if it has been previously guessed the program forces the user to guess another character. Otherwise it checks the word to see if that character is part of the target word. If it is, it reveals all of the positions with that target word. The program then asks the user to guess the target, keeping count of the number of guesses. When the user finally guesses the correct word, the program indicates how many guesses it took the user to get it right.
For this assignment you must start with the following "skeleton" of Java code. Import this into your Eclipse workspace and fill in the methods as directed. In addition, for this assignment you MUST add at least one extra method beyond the methods defined in the skeleton. This must be a method that does something useful - if you are stuck for an idea for a method, get the program working first and then see if there is some part of your main method that you can break out to be its own function or procedure instead.
Feel free to add any additional methods you find useful, but for all of the methods you add you must also add comments indicating what they do following the form of the rest of the comments in the code.
NOTE: If the file that the user enters for the word list does not exist or if it is an empty file with no words in it, your program should print the Goodbye! message and exit gracefully without crashing.

You can use the following word list for your program, but the list below is the one that the test cases will use. Create a new text file in your project directory and paste the following words into it. Note that your program must be able to deal correctly with blank lines (i.e. ignore them when it reads the file and do not add empty strings to the word list).

Circular Motion, Kinetic Energy, Work and Power
Wind energy is the fastest growing renewable energy source, the US has a goal of producing 20 percent of it’s electricity from wind by 2030. All of our energy options come with a set of pros and cons of varying degrees. One concern, which is minor unless it lands on your house, with wind turbines is ice throw off from the tips of the blade. Consider a 50 meter radius wind turbine (about 3 MW) rotating clockwise 15 times a minute with a hub height of 150 meters. Calculate the following for a 100 kg piece of ice at the tip of the turbine blade (r=50m):
a) The angular velocity of the rotating blades in radians per second, the period, or time it takes for a rotor blade to make one revolution and the frequency, or number of rotations made in one second.
b) The magnitude of the force required at the top circular path to keep the piece of ice in circular motion.
c) The magnitude of the force required at the bottom of the circular path to keep the piece of ice in circular motion.
d) The range or distance the piece of ice would travel if it was released at the highest point in the rotation. Consider clockwise rotation so the ice lands in the positive x direction.
e) The kinetic energy of the piece of ice upon release.
f) The kinetic energy of the piece of ice upon landing.
g) The work done by the gravitational force from release to landing.
h) Is this the maximum range? Is this the most likely point of release? Briefly explain your reasoning.
