- Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works. Next add the following public methods to the Address class and test them from main as you go: Write getters and…Description: Create a class named ComparableDog that extends Animal and implements Comparable interface. Implement the compareTo method to compare the Dogs on the basis of age. Write a test class to find the bigger age of two instances of ComparableDog Objects, and complement the ComparableDog class with the missing part. 1) The test program, the ComparableDog class, and its super class Animal are given as follows. // Main method public static void main(String[] args) { // Create two comparable Dogs ComparableDog dog1 = new ComparableDog(3); ComparableDog dog2 = new ComparableDog(4); System.out.println("Dog1:" + dog1); System.out.println("Dog2:" + dog2); if(dog1.compareTo(dog2) == 1) System.out.println("Dog1 is older than Dog2"); else if(dog1.compareTo(dog2) == -1) System.out.println("Dog1 is younger than Dog2"); else System.out.println("Dog1 and Dog2 have the same age"); }…Classes and Objects) Hand-write a complete Java class that can be used to create a Car object as described below. a. A Vehicle has-a: i. Registration number ii. Owner name iii. Price iv. Year manufactured b. Add all instance variables C. The class must have getters and setters for all instance variables d. The class must have two constructors, a no-args and a constructor that receives input parameters for each instance variable.
- Q 1: Access class members from the same package Note: ClassA and ClassB in this question are in the same package. public class ClassB { public int x = 1; int y = 2; private int z =3; } public class ClassA { public static void main(String[] args) { ClassB cb = new ClassB(); // System.out.print(cb.x); /* 1 */ // System.out.print(cb.y); /* 2 */ // System.out.print(cb.z); /* 3 */ } } 1.1- Which statement(s) are true? Choose all that apply. a. If statement 1 is uncommented, the code prints "1" to the output. b. If statement 2 is uncommented, the code prints "2" to the output. c. If statement 3 is uncommented, the code prints "3" to the output. .d. This code does not compile 1.2- Try to do the following: • Declare a character type variable myChar in the class ClassB, the variable myChar shouldn't be accessible through the object cb. Add a statement to the classA to test whether myChar is accessible.JAVA Language Caesar Shift Question: Modify the Caesar class so that it will allow various sized shifts to be used, instead of just a shift of size 3. (Hint: Use an instance variable in the Caesar class to represent the shift, add a constructor to set it, and change the encode method to use it.) import java.util.*; public class TestCipher { public static void main(String[] args) { int shift = 7; Caesar caesar = new Caesar(); String text = "hello world"; String encryptTxt = caesar.encrypt(text); System.out.println(text + " encrypted with shift " + shift + " is " + encryptTxt); } } abstract class Cipher { public String encrypt(String s) { StringBuffer result = new StringBuffer(""); // Use a StringBuffer StringTokenizer words = new StringTokenizer(s); // Break s into its words while (words.hasMoreTokens()) { // For each word in s…3.11 (Modified Account Class) Modify class Account (Fig. 3.8) to provide a method called wi th- draw that withdraws money from an Account. Ensure that the withdrawal amount does not exceed the Account's balance. If it does, the balance should be left unchanged and the method should print a message indicating "Withdrawal amount exceeded account balance." Modify class AccountTest (Fig. 3.9) to test method withdraw.
- Program: circle.cpp 1: Create a class Circle 2: Create two instances of the Circle class 1: Based on Program 13-1 in the textbook, create a class name “Circle” with the following declarations (hint: you can use PI=3.14): //Circle class declaration class Circle { private: double radius; public: void setRadius(double); double getRadius() const; double getArea() const; double getPerimeter() const; }; 2: Based on Program 13-2 in the textbook, create two instances of the Circle class, pizza1 and pizza2, which can have different size (radius).
