COUNTER CLASS SOLUTIONS

TASK – PART 1 – COUNTER CLASS

Here is my solution:

public class Counter

{

public int count;

public Counter()

{

count = 0;

}

public void inc()

{

count++;

}

public void dec()

{

count--;

}

public void reset()

{

count=0;

}

public String toString()

{

return "Count = " + count;

}

}

TASK – PART 2 – TESTING YOUR COUNTER CLASS

Here is my solution:

public class Question02

{

public static void main(String[] args)

{

//Create a Counter object.

Counter c1 = new Counter();

//Output the Counter to screen.

System.out.println(c1); //calls toString()

//Increment the Counter object.

c1.inc();

//Output the Counter to screen.

System.out.println(c1);

//Increment the Counter object twice.

c1.inc();

c1.inc();

//Output the Counter to screen.

System.out.println(c1);

//Decrement the Counter object.

c1.dec();

//Output the Counter to screen.

System.out.println(c1);

//Reset the Counter object.

c1.reset();

//Output the Counter to screen.

System.out.println(c1);

//Create a for loop that will loop ten times. Inside the loop, increment the counter.

for (int i=1; i<=10; i++) //loops 10 times

{

c1.inc();

}

//After the loop, output the counter to screen.

System.out.println(c1);

}

}
