COUNTER CLASS

Topics

• Simple class design, Using objects

TASK – PART 1 – COUNTER CLASS

You are to design and create a Counter class.  It allows us to create Counter objects that will have a count value.  That value will always be initially set to zero. 

The expected functionality is as follows:

• One can increment the counter by using the inc() method.

• One can decrement the counter by using the dec() method.

• One can reset the counter by using the reset() method.

• One can use the toString() method to get the value of the count inside the counter.

TASK – PART 2 – TESTING YOUR COUNTER CLASS

Inside the main function of a class named CounterTester, add the statements that do the following:

• Create a Counter object.
• Output the Counter to screen.
• Increment the Counter object.
• Output the Counter to screen.
• Increment the Counter object twice.
• Output the Counter to screen.
• Decrement the Counter object.
• Output the Counter to screen.
• Reset the Counter object.
• Output the Counter to screen.
• Create a for loop that will loop ten times. Inside the loop, increment the counter.
• After the loop, output the counter to screen.
