$2\mathrm{.}2$: Developing a "Tracking" Implementation of the IDialLock Interface

To get started, make your class implement the IDialLock interface. The IDE should prompt you to insert 'default $/$ stub' implementations of the abstract methods in the interface.

Next, add the following fields to the class:

int maxTicks $-$ this stores an upper bound on the digits around the lock.

int $s1,s2,s3-$ these are the three secret digits needed to open the lock.

int currentTick $-$ the number the lock's dial is currently pointing towards $($between $0..$maxTicks$).$
