Design a class named Stocks that contains: Private Data Members: A string data field named symbol for the stock’s symbol. A string data field named name for the stock’s name. A double data field and prevClosingPrice that stores the stock price for the previous day. A double data field named currentPrice that stores the stock price for the current day. Accessor and mutator functions for all data members. A method named getChangePercent( ) that returns the percentage changed from the previous closing price to the current price. The percentage is calculated by subtracting the previous closing price from the current price then, dividing by the current price. A method named nextDayPrice( ) that returns the predicted stock price for the next day assuming that the change percentage remains the same. Implement the class.

Mick’s Wicks makes candles in various sizes. Create a class for the business named Candle that contains the following data fields: color - of type String height - of type int price - of type double Create get methods for all three fields. Create set methods for color and height, but not for price. Instead, when height is set, determine the price as $2 per inch. Create a child class named ScentedCandle that contains an additional data field named scent (of type String) and methods to get and set it. In the child class, override the parent’s setHeight() method to set the price of a ScentedCandle object at $3 per inch.
Java - Constructors Create a class named Book that has the following attributes: Publisher - String Year Published - Integer Price - Double Title - String Create a constructor for the class Book that has the parameters from the attributes of the class. After, create a method for the class that displays all attributes. Ask the user for inputs for the attributes and use the constructor to create the object. Lastly, print the values of the attributes. Inputs 1. Publisher 2. Year Published 3. Price 4. Book Title XYZ Publishing 2020 1000.00 How to Win?

2. Car Class Write a class named car that has the following fields: ▪ yearModel. The year Model field is an int that holds the car's year model. ▪ make. The make field is a String object that holds the make of the car, such as "Ford", "Chevrolet", "Honda", etc. ▪ speed. The speed field is an int that holds the car's current speed. In addition, the class should have the following methods. ■ Constructor. The constructor should accept the car's year model and make as arguments. These values should be assigned to the object's year Model and make fields. The constructor should also assign 0 to the speed field.
Write a program named DemoJobs for Harolds Home Services. The program should instantiate several Job objects and demonstrate their methods. The Job class contains four data fieldsâ€”description (for example, wash windows), time in hours to complete (for example, 3.5), per-hour rate charged (for example, $25.00), and total fee (hourly rate times hours). Include properties to get and set each field except the total feeâ€”that field will be read-only, and its value is calculated each time either the hourly fee or the number of hours is set. Overload the + operator so that two Jobs can be added. The sum of two Jobs is a new Job containing the descriptions of both original Jobs (joined by and), the sum of the time in hours for the original Jobs, and the average of the hourly rate for the original Jobs. Harold has realized that his method for computing the fee for combined jobs is not fair. For example, consider the following: His fee for painting a house is $100 per hour. If a job takes 10 hours, he earns $1000. His fee for dog walking is $10 per hour. If a job takes 1 hour, he earns $10. If he combines the two jobs and works a total of 11 hours, he earns only the average rate of $55 per hour, or $605. Devise an improved, weighted method for calculating Harolds fees for combined Jobs and include it in the overloaded operator+() method. Write a program named DemoJobs2 that demonstrates all the methods in the class work correctly.
