- You need 5 java classes and these include Netflix Class (Parent class of Movie and TVShow class) Movie Class TVShow Class Test/TestDriver Class Database Class Please read the questions carefully. TestDriver is given for the other image.Object files: Instead of displaying the student data on the screen, change the program such that data in the array can be saved into an object file. Hint: Make the Student class serializable. 1. Add your own name as a new student into the array before having it saved into the object file. How is this possible. how would i be able to add my own name as a new student in my java source code?!?!?! here is a image of the source output: You have to answer only code and make it fast don;t waste time .Please create this make it simple Thank You very much Create a Java program that will store the book isbn number, title, and author in an array.Specifications:Classes:Books class and Technology class, where, Books is a superclass and Technology is a subclass.Technology will inherit all properties in the Books class.Books class has the following protected attributes: array of Isbn number, array of titles, and array of authors(consider one author per entry).Books class has Isbn Adder method that will add the ISBN number, author, and title to the arrays in the Books class..Books class also have a method to display all books.create a main method in the Technology class, and create an instance of Books.Add book, author, and title to the books class using ISBN adder method.

- CODE IN JAVA Please look at the attached image for the information about the format the code should be in The code should be in two different .java files one with getFirstName, getLastName and getZipCode; the other file would be containing the main method Design and implement an application that reads a sequence of up to 25 pairs of names and postal (zip) codes for individuals. Store the data in an object of a class called “NameAndZip”, designed to store a first name (String), last name (String), and a postal code (int). Create a driver class called “NameAndZipList”. Assume that each line of input will contain two strings followed by an integer value. You will then create an object for each line read in and store that object in an array of NameAndZip objects. After the Names and Codes have been entered, print the list in an appropriate format to the screen using the toString method in the NameAndZip class. To test the program enter 3 names and codes.Shape Class JAVA Implement the Shapehierarchy shown in figure below. Shape TwoDimensionalShape ThreeDimensionalShape Circle Square Sphere Cube Each TwoDimensionalShape should contain method getArea to calculate thearea of the two-dimensional shape. • Each ThreeDimensionalShape should have methods getArea and getVolume tocalculate the surface area and volume, respectively, of the three- dimensional shape. Add OneDimensionalShape with sub classes , and add more shapes to classes (TwoDimensionalShape , ThreeDimensionalShape ). Create a program that uses an array of Shape references to objects of each concrete class in the hierarchy. The program should print a text description of the object to which each array element refers. • Also, in the loop that processes all the shapes in the array, determine OneDimensionalShape, whether each shape is a TwoDimensionalShape or a ThreeDimensionalShape. If it is a TwoDimensionalShape, it is display ThreeDimensionalShape, display its area and volume. its…Create an object prototype called Gradebook that will pass an array of grades for a student as a parameter. - Create a boolean in Gradebook madeHonourRoll that will check whether or not the student has made honour roll - Create a function within Gradebook, that will calculate the average of the grades passed - Create a function outside of Gradebook, that will check if the grades are over an 80% average. Return madeHonourRoll as true if the student has made over 80% average. - Create a function outside Gradebook, called toString(), that will output to console whether or not the student has made the honour roll.

- java Create Class (any class) that include: Three variables Name ( default value is your name ) Id ( default value is your Id ) Print Method. Create parameterized constructor for that class and initialize it with your name and your id, try to use this keyword ? 3 create an object to that class and pass (1234, Dana) as parameters Ps : write your code in eclipse and send it as screen shotusing JAVA Create a class called Transcript which will take the following parameters for its constructor:- 1. The UoF ID of the student 2. The full name of the student 3. The year in which the student joined 4. The student's GPA score NOTE: The class also has a class field which is a 2D array with 32 elements containing the course codes and grades obtained by the studenta. Write a FractionDemo program that instantiates several Fraction objects and demonstrates that their methods work correctly. Create a Fraction class with fields that hold a whole number, a numerator, and a denominator. In addition: Create properties for each field. The set access or for the denominator should not allow a 0 value; the value defaults to 1. Add three constructors. One takes three parameters for a whole number, numerator, and denominator. Another accepts two parameters for the numerator and denominator; when this constructor is used, the whole number value is 0. The last constructor is parameterless; it sets the whole number and numerator to 0 and the denominator to 1. (After construction, Fractions do not have to be reduced to proper form. For example, even though 3/9 could be reduced to 1/3, your constructors do not have to perform this task.) Add a Reduce() method that reduces a Fraction if it is in improper form. For example, 2/4 should be reduced to 1/2. Add an operator+() method that adds two Fractions. To add two fractions, first eliminate any whole number part of the value. For example, 2 1/4 becomes 9/4 and 1 3/5 becomes 8/5. Find a common denominator and convert the fractions to it. For example, when adding 9/4 and 8/5, you can convert them to 45/20 and 32/20. Then you can add the numerators, giving 77/20. Finally, call the Reduce() method to reduce the result, restoring any whole number value so the fractional part of the number is less than 1. For example, 77/20 becomes 3 17/20. Include a function that returns a string that contains a Fraction in the usual display format—the whole number, a space, the numerator, a slash (D, and a denominator. When the whole number is 0, just the Fraction part of the value should be displayed (for example, 1/2 instead of 0 1/2). If the numerator is 0, just the whole number should be displayed (for example, 2 instead of 2 0/3). b. Add an operator*() method to the Fraction class created in Exercise 11a so that it correctly multiplies two Fractions. The result should be in proper, reduced format. Demonstrate that the method works correctly in a program named FractionDemo2. c. Write a program named FractionDem03 that includes an array of four Fractions. Prompt the user for values for each. Display every possible combination of addition results and every possible combination of multiplication results for each Fraction pair (that is, each type will have 16 results).
