OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Step by step
Solved in 2 steps
- The Inventory class contains a Private variable named strId. The variable is associated with the Public ItemId property. An application instantiates an Inventory object and assigns it to a variable named onHand. Which of the following can be used by the application to assign the string "XG45 to the strId variable? a. onHand.ItemId = "XG45" b. ItemId.strId = "XG45" c. onHand.strId = "XG45" d. ItemId.strId = "XG45"DateTimerPicker and MonthCalender class definitions follow.What attribute of the control needs be altered to allow access from code other than the form's class?
- All of question 2 will be in a class called userName2. Ask the user to enter their full name and store it in a variable name fullName. Then ask the user fortheir age and name it age. You will create a user name for the person that will be the first initial of their first name, then their lastname, and then their age. Look at the example below: Full name : Thomas Pasko Age: 30 The user name will be: TPasko30 Store each part separately. Store their first initial in a variable name firstInitial and store their last namein a variable named lastName. Use these variables to create the variable userName and print it out. Java ProgrammingWhich control property must be changed in order to access a control from outside the form's class?According to the following, which statement is true?private void ShowAnimalInfo(Animal animal) { } Question 12 options: It has an Animal variable as its parameter. You cannot pass an Animal object to the method when you call it. You cannot pass Dog objects although Dog is a class derived from Animal. All of the above.
- Create a class named Person that holds the following fields: two String objectsfor the person’s first and last name and a LocalDate object for the person’sbirthdate. Create a class named Couple that contains two Person objects. Create aclass named Wedding for a wedding planner that includes the date of the wedding,the names of the Couple being married, and a String for the location. Provideconstructors for each class that accept parameters for each field, and provide getmethods for each field. Then write a program that creates two Wedding objectsand in turn passes each to a method that displays all the details. Save the files asPerson.java, Couple.java, Wedding.java, and TestWedding.java.The final keyword should be used on any instance field, parameter, or local variable that will not or should not change after initialization. This protects against inadvertently changing the value elsewhere in the code. True/FalseCar Class Project The car classwill havethe following attributes: •year: an integer that holds the car's model year •model: a string that holds the make of the car •make: a string that holds the model of the car •speed: an integer that holds the car's current speed Your class should contain thefollowing: A docstring that briefly describes the class and lists the attributes. The docstring will serve as the documentation for your class. •A constructor (__init__ method) that takes the car's year model and make as optional arguments. The constructor will set the value of the speed attribute to 0.•An __str__ method that returns the car's year model and makein a string. •To test your class, create acar object and use the print function to verify that the constructor and __str__ methodsare working correctly. •An accessor method which returns the value stored in the speed instance variable. Call this method getSpeed(). •A modifier method called accelerate() which adds 5 to the speed variable…
