Create a class called Coin, which will represent a possibly loaded coin. Each coin is characterized by its face(HEADS or TAILS) and by its headProb, the probability that a toss of the coin will change the face value to HEADS. Implement methods to simulate a toss, change the headProb, and to print its current facevalue. Test the functionality in the main method of a separate class called Coinsimulation by simulating three, differently loaded, coins over 10 tosses. Implementation steps: 1) Create the Coin class (don't include the main method). Create the Coinsimulation class (with a main method). 2) Declare the instance variables that will represent the face of the coin and its head probability. Call these variables face (String) and headProb (double). Instance variables are declared outside of any method and do not include the static keyword. Declare them as private, so they cannot be directly accessible. This will prevent any inadvertent errors in using this class. Each Coin object instance will have its own version of these face and headProb variables. 3) Define the constructor method for the class. The constructor method is a non-static method that has the exact same name as the class, but no return type. This method is called automatically whenever we create a new object instance of this class. It should take as input one double value which will be used to initialize the headProb instance variable. The constructor should also initialize the face instance variable by calling the toss method (see below). 4) Define the toss method, which should change the face value of this object (the one on which the method is called) to "HEADS", with probability of headProb. See ex. 6 from lab #2 for implementation details. The method should be declared as public, but not static, without a return value. 5) Define the toString method. This non-static method is called automatically whenever we pass the object reference of this class to the println method. This will allow us to automatically print a textual representation of the Coin object. This method must have no input parameters and be public. It should return the value of the instance variable face. 6) Write code in the main method of the CoinSimulation class that tests the functionality of your implementation by creating three Coin objects, then loop for ten iterations. In each iteration, "toss" each of the Coin objects and display their face value.

Transcribed Image Text:Exercise 5 (Coin Class)
Create a class called Coin, which will represent a possibly loaded coin. Each coin is
characterized by its face(HEADS or TAILS) and by its headProb, the probability that a toss of
the coin will change the face value to HEADS. Implement methods to simulate a toss, change
the headProb, and to print its current face value. Test the functionality in the main method
of a separate class called CoinSimulationby simulating three, differently loaded, coins
over 10 tosses.
Implementation steps:
1) Create the Coin class (don't include the main method).
Create the CoinSimulation class (with a main method).
2) Declare the instance variables that will represent the face of the coin and its head
probability. Call these variables face (String) and headProb (double). Instance variables
are declared outside of any method and do not include the static keyword. Declare them as
private, so they cannot be directly accessible. This will prevent any inadvertent errors in
using this class. Each Coin object instance will have its own version of these face and
headProb variables.
3) Define the constructor method for the class. The constructor method is a non-static method
that has the exact same name as the class, but no return type. This method is called
automatically whenever we create a new object instance of this class. It should take as input
one double value which will be used to initialize the headProb instance variable. The
constructor should also initialize the face instance variable by calling the toss method (see
below).
4) Define the toss method, which should change the face value of this object (the one on
which the method is called) to “HEADS", with probability of headProb. See ex. 6 from lab #2
for implementation details. The method should be declared as public, but not static, without a
return value.
5) Define the toString method. This non-static method is called automatically whenever we
pass the object reference of this class to the println method. This will allow us to
automatically print a textual representation of the Coin object. This method must have no
input parameters and be public. It should return the value of the instance variable face.
6) Write code in the main method of the Coinsimulation class that tests the functionality
of your implementation by creating three Coin objects, then loop for ten iterations. In each
iteration, "toss" each of the Coin objects and display their face value.
