Step by step
Solved in 2 steps
- Computer Science JAVA 1. Discuss what a programmer-defined class would look like. Provide a code sample for a class that has a constructor, fields, and methods to support your point of view. 2. Discuss what inputs the main( ) class program should have. How will those inputs get passed to an object of the class? Provide a code sample to support your answer.Match the correct answer to the question. The information passed to a method in its parenthesis is referred to as: A self-contained block of program code that carries out some action is referred to as: The ability to create classes that share the attributes and methods of existing classes but with more specific features is known as: What reads the byte-code in chunks and compiles the chunk to machine language? Java identifier must not start with ……. and all the characters must be letters, digits, or the underscore ( _ ) symbol A. Inheritance B. JIT Compiler C.…Describe the most significant characteristics of classes and constructors that should be remembered.
- Class and object adapters serve distinct purposes. These ideas are also important to you.Design, code in Java, test and document a base class, Student. The Student class willhave the following information, and all of these should be defined as Private:A. Title of the student (eg Mr, Miss, Ms, Mrs etc)B. A first name (given name)C. A last name (family name/surname)D. Student number (ID) – an integer number (of type long)E. A date of birth (in day/month/year format – three ints) - (Do NOT use the Date class fromJAVA)The student class will have at least the following constructors and methods:(i) two constructors - one without any parameters (the default constructor), and one withparameters to give initial values to all the instance variables.(ii) only necessary set and get methods for a valid class design.(iii) method to write the output of all the instance variables in the class to the screen (which willbe overridden in the respective child classes, as you have more instance variables thatrequired to be output).(iv) an equals method which compares two student objects and…Why are abstraction and composition part of good software design? A. By putting duplicated code to one common location it reduces the number of places where we need to look for errors in the code. B. All options are true. C. They reduce the amount of code to write. D. They keep each specific class simpler. E. Extending the code with new specific classes is easier because they can make use of previously written code.
- 6.b.Fast in java coding please. Thank you 1. Abstract classes and interfaces can both be used to model common features.How do you decide whether to use an interface or a class?2. What is Garbage Collection and how can you mark an object for GarbageCollection.Language: Python First, define a Product class that includes all the information about a single product. a. You will need a constructor to initialize new instances. Objects of this class should have three instance variables: name, price, and quantity in-stock. b. Add a method to your class that takes an integer count and determines whether that many of the product are in stock. c. Add another method that takes a count and returns the total cost of that many of the product. d. Finally, add a method that takes a count and removes that many of the product from the stock. Next, replace the three product lists with a single list of Product instances. Modify the rest of the code to correctly use the attributes and methods of the Products in the list. product_names = ["Ultrasonic range finder", "Servo motor", "Servo controller", "Microcontroller Board", "Laser range finder", "Lithium polymer battery" ]product_prices = [2.50, 14.99, 44.95, 34.95, 149.99,…[JAVA] Answer these questions according to the UML class schema given above. You may need to extract hidden information from the schema and add necessary code. You don’t have to consider inconsistencies other than the ones explicitly stated in questions. You will be writing some part of hotel management software. Pay attention to the following details about the program logic when writing your code: Question 1: Write the source code of classes CriticalException and NonCriticalException. Question 2: Write the source code of classes Person and Employee. Question 3: Write the source code of class Room. The details of its methods are as follows: setCapacity: If one attempts to set a negative capacity or a capacity greater than maxRoomCapacity, a CriticalException is generated. setDailyRate: A room’s daily rate must not be changed while there are guests in it. Otherwise, a NonCriticalException is generated. Constructor must use the setter methods described above. addGuest: A guest must not…
- Discuss the concept of multiple interfaces in a single class. What are the advantages and potential challenges of implementing multiple interfaces in a class?We would like to design a software system so that ... we can easily add new functionality without large changes in our software design or code-level implementation. we can easily add or remove easily new functionality without large changes in our software design or code-level implementation. we can easily modify the existing functionality without large changes in our software design or code-level implementation. we can easily use the software system in different scales, i.e., create more or less instances of classes. we can do all of the above.Differentiate these terms with minimum words.d) <<extend>> and <<include>> e) Generalization and Specializationf) Concrete class and Interface classg) Brief Use-case and Casual Use-case
