Question

Java expert please help me fill-in-the-blank question. If the question you are not sure, please just don't answer. Thank you so much for your help.

Assume we have a class Counter that takes a step value and increments or decrements a current value by the step. The current value starts at 0. Counter has, in addition to increment and decrement, methods

int getCurrent() // returns the current value

and

boolean isEven() // returns true if and only if the current value is even

Complete the JUnit test method for the following snippet:

Counter c = new Counter(3);

c.increment();

c.increment();

int retrievedVal = c.getCurrent();
