Specify, design, and implement a class that can be used in a program thatsimulates a combination lock. The lock has a circular knob with the numbers 0through 39 marked on the edge, and it has a three-number combination, which wewill call x, y, and z.In order to open the lock, you must turn the knob clockwise at least one entirerevolution, stopping with x at the top; then you turn the knob counterclockwise,stopping the "second" time that y appears at the top; finally, you turn the knobclockwise again, stopping the next time that z appears at the top. At this point, youmay open the lock.Your "Lock" class should have a constructor that initializes the 3-numbercombination (use O, 0, 0 for default arguments in the default constructor).Also, provide the following methods:a) To alter the lock's combination to a new 3-number combinationb) To turn the knob in a given direction until a specified number appears at thetop. (You also must show all of the numbers in the output as the lock is beingturned - could use a for loop)c) To close the lockd) To attempt to open the locke) To inquire about the status of the lock (open or shut)f) To tell what number is currently at the topWrite a complete Java program that uses all of the above methods in the output.

Question

NOTE: Don't Copy from the Chegg,

Use this method for a given question

3 LockADT – Show the interface and all abstract methods

LockDataStructureClass – Show the following methods: default constructor, overloaded constructor, copy constructor, setX, setY, setZ, alter (change the lock’s combination to the numbers passed) turn (use for loops to show the dial turning), close (locks the lock), attempt (tries to unlock the lock – calls turn( ), inquire (locked or unlocked), current (returns the number the dial is pointing to), toString

LockClientDemoClass – You should have a Lock object instantiated and a menu method that displays:

1: set lock combination

2: close lock

3: check status

4: attempt to open lock

5: check what the dial is currently pointing at

6: exit the program

Example of turning the lock:

First number (17): 0 39 38 37 … 0 39 38 …17

Second number (26): 17 18 19 ... 38 39 0 1 2 … 17 18 19 20 21 22 23 24 25 26

Third number (9): 26 25 24 23 …. 12 11 10 9 (go directly to the number)
