(CLO3) Read the following description and answer the following questions about it:
Problem Description: A car dealership allows customer to purchase their new cars with different options. At this time, those options
are color, model, and air condition, as shown below in class CustomerOrder. Of course, the dealership wants the software to be
flexible enough to be able to add more options in the future, if needed.
CustomerOrder
-carColor: String
-carModel: String
-hasAirCondition: boolean
Q1) Write the full required code in Java to use the Builder design pattern to create class CustomerOrder.
Q2) Write a Java main() method to create an object of class CustomerOrder with color "red" and without air condition.
Q1) Write a method that checks whether two words are anagrams. Two words are anagrams if they contain the same letters in any order. For example, "silent" and "listen" are anagrams. Write a test program that prompts the user to enter two strings and, if they are anagrams, displays "anagram", otherwise displays "not anagram".
Note: The header of the method is as follows:
public static boolean isAnagram(String s1, String s2)
Sample Input #1:
Enter two strings:
Silent
listen
Sample Output #1:
The string “Silent” and “listen” are anagrams.
Sample Input #1:
Enter two strings:
teach
peach
Sample Output #1:
The string “teach” and “peach” aren’t anagrams.
Do not use regular expressions in your solution for this exercise. Write a program that checks to see if an input password is valid or not. In this exercise, a valid password has the following characteristics:
It contains at least eight characters.
It contains at most 12 characters.
It contains only alphabetic characters, digits and the underscore (‘_’) character.
It does not start with a digit.
It has a mix of upper-case and lower-case characters.
Your class must contain the following method: public static String checkPassword(String input)
This method receives a possible password as input and returns only the String“OK” if the password is valid. If the password is not valid then you can return the reason(s) for that as the return value. This is not a part of the requirements, however, and you don’t need to do that. You can simply return null for an invalid password.

One such technique is known as theBabylonian method. It approximates the square root of a number, n, by repeatedlyperforming a calculation using the following formula: nextGuess = (lastGuess + n / lastGuess) / 2 When nextGuess and lastGuess are almost identical, nextGuess is theapproximated square root. The initial guess can be any positive value (e.g., 1).This value will be the starting value for lastGuess. If the difference betweennextGuess and lastGuess is less than a very small number, such as 0.0001,you can claim that nextGuess is the approximated square root of n. If not, next-Guess becomes lastGuess and the approximation process continues. Implementthe following method that returns the square root of n.public static double sqrt(long n)" I have my java code here " import java.util.Scanner;public class Main2 {public static void main(String[]…arrow_forward
