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) Demonstrate all behaviors (actions, methods) of the lock.

Written in Python It should have an init method that takes two values and uses them to initialize the data members. It should have a get_age method. Docstrings for modules, functions, classes, and methods

JAVA PROGRAM For this program, you are tasked to implement the Beverage class which has the following private properties: name - a string value volume - this is an integer number which represents its current remaining volume in mL isChilled - this is a boolean field which is set to true if the drink is chilled It should have the following methods: isEmpty() - returns true if the volume is already 0 {toString() - returns the details of the object in the following format: {name} ({volume}mL) {"is still chilled" | "is not chilled anymore"}.Example returned strings: Beer (249mL) is still chilled Water (500mL) is not chilled anymore A constructor method with the following signature: public Beverage(name, volume, isChilled) Getter methods for all the 3 properties. Then, create two final subclasses that inherit from this Beverage class. The first one is the Water class which has the additional private property, type, which is a String and can only be either "Purified", "Regular",...

Implement a nested class composition relationship between any two class types from the following list: Advisor Вook Classroom Department Friend Grade School Student Teacher Tutor Write all necessary code for both classes to demonstrate a nested composition relationship including the following: a. one encapsulated data member for each class b. inline default constructor using constructor delegation for each class c. inline one-parameter constructor for each class d. inline accessors for all data members e. inline mutators for all data members

Finish the TestPlane class that contains a main method that instantiates at least two Planes. Add instructions to instantiate your favorite plane and invoke each of the methods with a variety of parameter values to test each option within each method. To be able to test the functionality of each phase, you will add instructions to the main method in each phase.

Can you please help me with this, its in java. Thank you. Write classes in an inheritance hierarchy Implement a polymorphic method Create an ArrayList object Use ArrayList methods For this, please design and write a Java program to keep track of various menu items. Your program will store, display and modify salads, sandwiches and frozen yogurts. Present the user with the following menu options: Actions: 1) Add a salad2) Add a sandwich3) Add a frozen yogurt4) Display an item5) Display all items6) Add a topping to an item9) QuitIf the user does not enter one of these options, then display:Sorry, <NUMBER> is not a valid option.Where <NUMBER> is the user's input. All menu items have the following: Name (String) Price (double) Topping (StringBuilder or StringBuffer of comma separated values) In addition to everything that a menu item has, a main dish (salad or sandwich) also has: Side (String) A salad also has: Dressing (String) A sandwich also has: Bread type...

Java programming - please see attched image for initial instruction before the following below. Write a subclass of VowelSeparator that adds three additional methods and a constructor. The class should be named VowelSeparatorAndCounter. Here are the methods to add: void setString(String s) This method should replace the string stored by the object with s. If the argument is null then the method should throw an IllegalArgumentException. (This is an unchecked exception) int getVowelCount() This method should return the number of vowels in the string.int getNonVowelCount() This method should return the number of characters in the string that are not vowels. Write a static method that accepts an array of VowelSeparatorAndCounter objects and returns the total number of vowels contained in all of them. It should have the following signature: public static int totalVowelCount(VowelSeparatorAndCounter[] a)

g) Make a class Class (as in a class of students, not a class as in a class of objects) that stores several Student objects. Store a list of students in an attribute called students. The initializer method should initialize the class as an empty class (no students). Implement a method add_student() that takes an object of class Student and adds it to class. Implement method pass_rate() that determines the fraction of students that pass the class (have a grade of >= 6). python code!!
