II. Answer the following questions; provide appropriate explanations for your answer. 1. Every additional line of code is an opportunity for a defect. Discuss the ways in which inheritance promotes defect reduction. 2. a. Explain two usages of the super keyword, and state some advantages of each type of usage. b. A method decode() is declared in a parent class, and also in the child class. How can you access the decode() of the parent from within the child? c. Write up to two line codes that perform each of the following tasks: į. Specify that the class Orange inherits from class Fruit. ii. Call superclass Fruit's constructor from subclass Orange's constructor. Assume that the superclass constructors receives two Strings, one for shape, another for color; and an integer for the calories.

For each of the following two code sketches complete the following three steps: Use abstraction and information hiding to improve the design of the code sketch. Your answer should be in form of a code sketch (i.e., make the design clear by providing class names, method names, and examples of how classes and objects will be used). Do not construct an entire detailed program. Describe the negative consequences of poor use of abstraction and information hiding in each code sketch. Describe how your use of abstraction and information hiding avoids the negative consequences listed in the previous step. class Vehicle { } public enum FuelType { DIESLE, ELECTRIC, HYDROGEN, LNG, JET_FUEL } public FuelType fuelType; public void add Fuel (double amount) { if (fuelType == FuelType.DIESEL) { // code for adding diesel fuel... } else if (fuelType == FuelType.ELECTRIC) { // code for adding electric fuel... } else if (fuelType == FuelType.HYDROGEN) { // code for adding hydrogen fuel... } else if…
Why is the ability to redefine a method important in object-oriented programming?Choose all options that apply.(a) Because it allows us to add extra work to a method.(b) Because it allows us to introduce abstract methods that are redefined as concrete methods.(c) Because it allows us to provide a more accurate or faster definition in a subclass.(d) Because it allows us to disable a method in a subclass.(e) Because it allows us to change the meaning of a method.
Write a Java program with the following specifications:(read the steps carefully) (thank you in advance)1. Define the attributes of the PaySlip class. Define the constructor for this class. 2. Define the setters (mutators) and the getters (accessors) for the PaySlip class. 3. Define also the custom methods in the PaySlip class as follows but not limitedto determineWithholdingTax( ) and computeCompensation( ). 4. Input the employee name, basic salary, and number of overtime (OT) hours.Data input should be done in the main method. The final output as described in#9 should be generated in the main method, as well. (The screen shot of table is uploaded.)5.

Assume that you are working in a well reputed software house. You are working in a way that you evaluate the assertions after the method completes. You are supposed to specify that what elements are involved in such a kind of assertion. Determine and discuss what kind of assert expression is it. What is guaranteed by this particular expression and what happens in case it violates? Provide sample code in java if needed.
Complete the following piece of java code (MyDate class). The semicolon after each method must be replaced with a set of curly braces, in which the instructions for the method are placed. Think of one error and add error handling to your program Create a class diagram for the MyDate class. Create a test class to test mydate (main class with a main method) public class MyDate { /* If no arguments were provided then default the date January 1st, 1970 (epoch time). */ public MyDate(); /* Creates a new MyDate from an existing MyDate */ public MyDate( MyDate date); /* Creates a new MyDate from a day, month, and year */ public MyDate( int day, int month, int year); /* Returns the day of the month for this MyDate */ public int getDay(); /* Returns the month of the year for this MyDate */ public int getMonth(); /* Returns the year for this MyDate */ public int getYear(); /* Returns true if this MyDate represents a date in a leap year */…
Pls answer part a and b accordingly. Read this first: SHOW ALL YOUR WORK. PROGRAM SEGMENTS ARE TO BE WRITTEN IN JAVA. Assume that the classes listed in the Java Quick Reference have been imported where appropriate. Unless otherwise noted in the question, assume that parameters in method calls are not null and that methods are called only when their preconditions are satisfied. In writing solutions for each question, you may use any of the accessible methods that are listed in classes defined in that question. You shouldn't write significant amounts of code that can be replaced by a call to one of these methods . A manufacturer wants to keep track of the average of the ratings that have been submitted for an item using a running average. The algorithm for calculating a running average differs from the standard algorithm for calculating an average, as described in part (a). A partial declaration of the RunningAverage class is shown below. You will write two methods of the…
Given the following class diagram, interfaces and classes that model various kinds of animals. What will be the errors in the main method? For each error, indicate the line number of each incorrect statement and explain in one sentence why it is wrong.

In writing solutions for each question, you may use any of the accessible methods that are listed in classes defined in that question. Writing significant amounts of code that can be replaced by a call to one of these methods will not receive full credit. This question involves the use of check digits, which can be used to help detect if an error has occurred when a number is entered or transmitted electronically. An algorithm for computing a check digit, based on the digits of a number, is provided in part (a). The CheckDigit class is shown below. You will write two methods of the CheckDigit class. public class CheckDigit { /** Returns the…

The hidden word contains only capital letters and has a length known to the player. A guess contains only capital letters and has the same length as the hidden word. After a guess is made, the player is given a hint that is based on a comparison between the hidden word and the guess. Each position in the…
8. Discuss whether the following task is possible to implement. The argument and the discussion are important.

You should check statically whether it is possible that you end up in an infınite cycle and issue a warning.
Convert the following UML diagram into the Java code. Write constructor, mutator and accessor methods for the given class. Create an instance of the class in a main method using a Demonstration class. Note: The structure of the class can be compiled and tested without having bodies for the methods. Just be sure to put in dummy return values for methods that have a return type other than void. Exercise Log ExerciseID: integer ExerciseCategory: string TimeSpent: float Calories: float
