- Java programming please Support computing sales tax in the CashRegister class. The tax rate should be supplied when constructing a CashRegister object. Add recordTaxablePurchase and getTotalTax methods. (Amounts added with recordPurchase are not taxable.) The giveChange method should correctly reflect the sales tax that is charged on taxable items. Please add the method to the CashRegisterTester. The input and output are also provided below. CashRegister class: import java.util.Scanner; public class CashRegister { private double purchase; private double payment; /** Constructs a cash register with no money in it. */ public CashRegister() { purchase = 0; payment = 0; } /** Records the sale of an item. @param amount the price of the item */ public void recordPurchase(double amount) { purchase = purchase + amount; } /** Processes a payment received from the customer. @param amount the amount of the payment */…Design a class that holds the following personal data: name, address, age, and phone number. Write appropriate accessor and mutator methods. Also, design a program that creates three instances of the class. One instance should hold your information, and the other two should hold your friends’ or family members’ information. very basic ALGORITHM in PSUEDOCODE NOT PYTHON. Use fictitious information.Write complete java code for scenario given: Consider a Java class that you could use to get an acceptable integer value from the user. An object of this class will have the attributes: Minimum accepted value Maximum accepted value • Prompt String and the following method: getValue() displays the prompt and reads a value from the user. If the value read is not within the allowed range, the method should display an error message and ask the user for a new value, repeating these actions until an acceptable value is entered. The method then returns the value read.

Modify a dealership's Automobile class so it includes fields for an id (ID number), make, model, color, year, and mpg (miles per gallon). Include get and set methods for each field. Do not allow the ID to be negative or more than 9999; if it is, set the ID to 0. Do not allow the year to be earlier than 2005 or later than 2019; if it is, set the year to 0. Do not allow the miles per gallon to be less than 10 or more than 60; if it is, set the miles per gallon to 0. Include a constructor that accepts arguments for each field value and uses the set methods to assign the values. The TestAutomobile.java file has been provided to test your implementation. Here is the code so far: public class Automobile { private int id; private String make; private String model; private String color; private int year; private double mpg; public Automobile(int id, String make, String model, String color, int year, double mpg) { } public…
- Create a program that will count the number of numeric characters in an input string. The program should be able to ask the user for the input string and should be able to display the number of numeric characters on the screen. For this exercise, you should create your class to handle the different operations. Remember that any input/output operations should be done in the main method while all calculations should be done inside the class. Remember that you need to apply encapsulation in your class. Sample Output: Enter a string: Hello 123 Number of numeric characters: 3Java. Modify a dealership's Automobile class so it includes fields for an id (ID number), make, model, color, year, and mpg (miles per gallon). Include get and set methods for each field.

The application should use an object of class Random once to roll the first die and again to roll the second die. The sum of the two values should then be calculated. Each die can show an integer value from 1 to 6, so the sum of the values will vary from 2 to 12, with 7 being the most frequent sum, and 2 and 12 the least frequent.
- JAVA HELP PLEASE! Write a class Rectangle that has only the following public methods (you can add other non-public methods if you think you need them): Write a constructor that creates a rectangle using the x, y coordinates of its lower left corner, its width and its height (the parameters must be in that order). Creating a rectangle with non-positive width or height should not be allowed; throw an IllegalArgumentException for those cases. The values of x and y are allowed to be negative. Write a method overlap(Rectangle other). This method should return true if this rectangle overlaps with other, false otherwise. Rectangles that touch each other are not considered to be overlapping. Write a method toString that returns a String. The string should be formatted exactly as:“x:2, y:3, w:4, h:5”without the quotation marks and replacing the numbers with the actual attribute values of the object. A class called Rectangle exists in Java already. You are not allowed to use this class in any…JAVA Practice Question for Midterm Write a class with a constructor that accepts a String object as its argument. The class should have a method that returns the number of vowels in the string, and another method that returns the number of consonants in the string. Demonstrate the class in a program by invoking the methods that return the number of vowels and consonants. Print the counts returned. Imagine you are developing a software package for an online shopping site that requires users to enter their own passwords. Your software requires that users’ passwords meet the following criteria: The password should be at least six characters long. The password should contain at least one uppercase and at least one lowercase letter. The password should have at least one digit. a program that asks the user to enter a password, then displays a message indicating whether it is valid or not.FOR JAVA Create a class named Product that has ID, price and stock as fields. This class must have two constructors; one constructor must take all its fields as parameters, second constructor must take ID and price as parameters and set stock to 0. Also implement the following methods: • String toString(): Returns a brief summary about the object. • void sell(int): Takes a parameter that represents the amount to sell. Checks if stocks are sufficient. If so, it updates the stock and prints the total price. Else it prints a warning to user. Create 3 instances of Product class and test your methods.
