Hello. General Java programming questions.Where should imports be located? In the driver/ location of main OR do they go in the class files? I've never gotten a good answer.Also, is there an easy way determining which imports I need? I generally write my code in a text file.Thanks.

Using classes, design an online address book to keep track of the names, addresses, phone numbers, and dates of birth of family members, close friends, and certain business associates. Your program should be able to handle a maximum of 500 entries. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables. Define a class extPersonType using the class personType (as defined in Example 10-10, Chapter 10), the class dateType (as designed in this chapters Programming Exercise 2), and the class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information. Use constructors to automatically initialize the member variables. Define the class addressBookType using the previously defined classes. An object of the type addressBookType should be able to process a maximum of 500 entries. The program should perform the following operations: Load the data into the address book from a disk. Sort the address book by last name. Search for a person by last name. Print the address, phone number, and date of birth (if it exists) of a given person. Print the names of the people whose birthdays are in a given month. Print the names of all the people between two last names. Depending on the users request, print the names of all family members, friends, or business associates.

JAVA PROGRAMMING (TRUE OR FALSE) No further explaination needed. Classes in the java·lang package may be used directly if they are imported first using an import statement(True/False) The fields and methods of a child/sub class are only those inherited from the parent/super class.(True/False) A reference/object of super class type can hold/assume any object of its sub class type.(True/False) An import statement is necessary to use/access a classin the same package.(True/False) A private data field is accessible only by other classes via the exposed methods of its class.(True/False)
Using Java ((Abstract Class and Interface)) 13.11 (The Octagon class)) Write a class named Octagon that extends faces. Assume that all eight sides of the Comparableand Cloneable inter-be computed useing the fllowing formula : area =(2 + 4 / square root of 2)* side * side Draw the UML diagram that involves Octagon, GeomtricObject,Comparable and Cloneable. Write a test program that create a new Object using the clone method and comoare the two object using the compareTo method.
create java classes to manage CD and publisher and expand the classes so that you can handle book and DVD. This should be done with the help of inheritance. A general superclass, Media, will be created to be able to reuse common data and functionality between the CD, Book and DVD classes. These 3 class must thus inherit their properties from the Media class. The Media class is a superclass for different type of media. you will collect instance variables and methods that are common to all type of media. All instance variables in the class are declared as protected, which mean that classes that inherit from Media have a direct access to these variables.The class only needs 2 constructors. One takes 3 argument that set values for all instance variables in the class, and the other takes no arguments but sets certain default values of the instance variables. If you think that more designers are necessary, you can add. In the setLength method, perform a check so that the value submitted is…
Create a classstudent which includes parameters roll_no, name and address and consider as super class.Then create sub class test with parameters marl1, mark2, mark3 and mark4. Then create another sub class result with parameters total_marks, percentage and grade. Apply multi level inheritance. Here Student class is the super class for test class and test class is super class of resultclass. Implement a java application in which obtain the details roll_no, name, address, marl1, mark2, mark3 and mark4 from user side andthen print total_marks, percentage and grade.Studentàtestàresult
You have to make a program that handles information related to final semester students. Students have to take Project or Thesis. It is a special Course mandatory for all students of CSE department. Every student should make a proposal for it. There should be title, field and objective in the proposal for both Project & Thesis along with student id and name. Moreover, Project includes an outcome and Thesis includes an innovation. a. Make required class with necessary attributes and methods using Inheritance b. Ensure proper Encapsulation to design your classes to answer question (a). c. Make provision for a student to organize proposal. d. Make a main method to print all info needed for proposal.
Java Question - Based on code, which answer out of the choices "A, B, C, D, E" is correct. Question has one correct answer. Thank you. Part 2 - 10. Given the following code, which statement is true? class Water() { ... }class Juice() extends Water { ... }class Apple() { ... }class ApplePie() { Apple a1 = new Apple(); }class AppleJuice() { Apple a1 = new Apple(); Water w1 = newWater(); } A. Juice is a superclass and Water is a subclass.B. ApplePie is a superclass of Apple.C. ApplePie is a composite class that contains an instance of Apple class.D. AppleJuice is a superclass that contains an instance of Apple class and an instance of Water.E. Water is a composite class that contains an instance of Juice.5
Create an abstract class named Course that can be used with course allocation mechanism of an enterprise. The Course class should track the course Id Number, course Title and course Credit Hours with appropriate accessor/getter and mutator/setter methods. Define an equals (Course obj) method, that returns true if caller and input argument course object have identical course Id Number. Also define an abstract method double getCourseEnrollmentFee(). Next, create two additional classes named ElectiveCourse and CoreCourse that are derived from Course. Finally, create an overridden method named getCourseEnrollmentFee() calculate and returns the total fee for that course. Elective course has Rs. 10,000 per credit hours and Core has Rs. 13,000 per credit hours.
