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;

   }

}
