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…use the following partial class definitions:public class A1{public int x;private int y;public int z;…}public class A2 extends A1{public int a;private int b; …}public class A3 extends A2{private int q;…} 2) Which of the following lists of instance data are accessible in class A2?a) x, y, z, a, bb) x, y, z, ac) x, z, a, bd) z, a, be) a, b

- Instructions: Implement the Java class Customer by following the UML class diagram provided below. Implementation details: The class constructor must receive the arguments in the following order: String firstName, String lastName, String address, String cardNumber, int pin, String username The password must be generated inside the class constructor by the class method generatePassword(). The password to be generated must meet the following criteria: Must have at least one numeric character. Must have at least one lowercase character. Must have at least one uppercase character. Must have at least one special symbol among @#$% Password length to be generated is fixed and equal to 12. Do please use SecureRandom() class to achieve randomness during password generation. toString() return value format must be as follows:Customer [firstName='John', lastName='Monkey', cardNumber='11336688', pin='1234', username='j.monkey', password='zF$7zR#1lFAo', address='453 Manin st,…Description: Create a class named ComparableDog that extends Animal and implements Comparable interface.

- In number theory, a value can be categorized as a natural number (a whole number >0, often denoted ℕ), an integer (zero or a positive or negative whole number, including the natural numbers, often denoted ℤ), or a real number (which includes the natural numbers and integers, along with all other positive and negative numbers that are not integers, often denoted ℝ). a) write a definition for a number class that contains: (i) A single field suitable for storing either a natural number, or an integer, or a real number; (ii) Setter and getter methods for manipulating this field; (iii) A constructor that initializes new objects of number to have the value 1 (unity); (iv) a method that determines which kind of number is currently stored (returning 0 if the number is real and an integer and a natural number, 1 if the number is real and integer but not a natural number, and 2 if the number is real but neither an integer nor a natural number) Java code neededJAVA 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.
