Write the definition of a class Counter containing: An instance variable named counter of type int An instance variable named limit of type int.

LANGUAGE: JAVA

CHALLENGE:

Write the definition of a class Counter containing:
An instance variable named counter of type int
An instance variable named limit of type int.
A constructor that takes two int arguments and assigns the first one to counter and the second one to limit
A method named increment . It does not take parameters or return a value ; if the instance variable counter is less than limit, increment just adds one to the instance variable counter.
A method named decrement. It also does not take parameters or return a value ; if counter is greater than zero, it just subtracts one from the counter.
A method named getValue that returns the value of the instance variable counter.

SOLUTION:

public class Counter
{
    private int counter;
    private int limit;

    public Counter (int number1, int number2)
    {
        counter = number1;
        limit = number2;
    }
    public void increment()
    {
        if (counter < limit)
        counter ++;
    }
    public void decrement()
    {
        if (counter > 0)
        counter –;
    }
    public int getValue()
    {
        return counter;
    }
}
