Write a class called Counter that represents a simple tally counter, which might be used to count people as they enter a room. The Counter class should contain a single integer as instance data, representing the count. Write a constructor to initialize the count to zero. Write a method called click that increments the count and another method called get Count that returns the current count. Include a method called reset that resets the counter to zero. Finally, create a driver class called CounterTest that creates two Counter objects and tests their methods.

Code is in java

Explanation:

Code is self explanatory, added come comments to explain more about the code.

public class CounterDriver {

public static void main (String[] args) {

/ / Creating counter first object

Counter counter1 = new Counter ();

//performing 2 clicks

counter1. click ();

counter1. click ();

/ / displaying counter 1 click count

System. out. println ("Total Number of counter1 clicks : "+counter1. getCount ());

/ / resetting counter 1 click count

counter1. reset ();

/ / again displaying click count which will be 0 after reset

System. out. println ("Total Number of counter1 clicks : "+counter1. getCount ());

/ / Same operation goes with counter 2

/ / the only difference is that it performs 3 clicks

Counter counter2 = new Counter ();

counter2. click ();

counter2. click ();

counter2. click ();

System. out. println ("Total Number of counter2 clicks : "+counter2. getCount ());

counter2. reset ();

System. out. println ("Total Number of counter2 clicks : "+counter2. getCount ());

}

}

class Counter{

int count;

/ / defining constructor which will initialize count variable to 0

public Counter () {

this. count=0;

}

/ / adding click method to increment count whenever it's called

public void click () {

this. count++;

}

/ / getCount method will return total count

public int getCount () {

return this. count;

}

/ / reset method will set count to 0

public void reset () {

this. count = 0;

}

}
