So you take the current volume, increase it by 2.5%, and then find the cube root to calculate the new side length. You can use the built in function called cbrt, part of the math library, to find the cube…
- Rectangle Object Monitoring Create a Rectangle class that can compute the total area of all the created rectangle objects using static fields (variables). Remember that a Rectangle has two attributes: Length and Width. Implement the class by creating a computer program that will ask the user about three rectangle dimensions. The program should be able to display the total area of the three rectangle objects. For this exercise, you are required to apply all OOP concepts that you learned in class. Sample output: Enter Length R1: 1 Enter Width R1: 1 Enter Length R2: 2 Enter Width R2: 2 Enter Length R3: 3 Enter Width R3: 3 The total area of the rectangles is 14.00 Note: All characters in boldface are user inputs.Create a class for Subject containing the Name of the subject and score of the subject. There should be following methods: set: it will take two arguments name and score, and set the values of the attributes. If score is less than 0 or greater than 100.0 then a message should be displayed “Incorrect score” and score should be set to Zero. set: it will take one double value as argument and set the value of score only. If score is less than 0 or greater than 100.0 then a message should be displayed “Incorrect score” and score should be set to Zero. display: it will display the name and score of the subject. Like “Name : Math, Score: 99.9” getScore: it will return the value of score. greaterThan: it will take subject’s object as argument, compare the calling object’s score with argument object’s score and return true if the calling object has greater score. Create a class “Main” having main method to perform following tasks. Create two objects of Subject class having value “Math, 99.9”…Create a class for Subject containing the Name of the subject and score of the subject.

- Design a class named Rectangle to represent a rectangle. The class must have the following: • double data fields named width and height. The default values are 1 for both width and height A no-argument constructor that creates a default bag. A constructor that creates a rectangle with the specified width and height A getParameter() method to return the perimeter. • A getArear() method to return the area of the Rectangle. Create two Rectangle objects. One with width 4.0 and height 10.0. The other object has width 6.3 and height 10.5.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.Create a class named Person that holds the following fields: two String objectsfor the person’s first and last name and a LocalDate object for the person’sbirthdate. Create a class named Couple that contains two Person objects. Create aclass named Wedding for a wedding planner that includes the date of the wedding,the names of the Couple being married, and a String for the location. Provideconstructors for each class that accept parameters for each field, and provide getmethods for each field. Then write a program that creates two Wedding objectsand in turn passes each to a method that displays all the details. Save the files asPerson.java, Couple.java, Wedding.java, and TestWedding.java.
- Create a class named Ship that has two private fields one for the name (string) of the ship, and the other for the year (string) the ship was built. The class contains- a parameterized constructor to set the values of each field- get methods for each of the fields- display method to display the ship’s information.Create a class named CruiseShip that descends from Ship class. CruiseShip class should have a private field for the maximum number of passengers (int).The class contains- a parameterized constructor to set the value of the field- get and set method for the field- a display method that overrides ship class display method anddisplay CruiseShip information. Create an application/class named CruiseShipDemo that allows a user toenter values to create 5 CruiseShip objects and save them in the array. Display the records.The CruiseShipDemo class should have a method named update to updatethe CruiseShips information. The method prompt the user for the ship name, if the requested record…Create the StockTask1 Java project Create a Stock object class that contains the following information: The symbol of the stock is stored in a private string data field called symbol. The stock's name is stored in a private string data field called name. previousClosingPrice is a private double data area that stores the stock price for the previous day. currentPrice is a private double data area that stores the stock price at the current time. A constructor for creating a stock with the given symbol and name. For the data fields, there are accessor methods (get-methods). For the data fields, there is a mutator method (set-methods). A method named getChangePercent()that returns the percentage changed from previousClosingPrice to currentPrice.

Write a FractionDemo program that instantiates several Fraction objects and demonstrates that their methods work correctly. Create a Fraction class with fields that hold a whole number, a numerator, and a denominator. In addition: Create properties for each field. The set access or for the denominator should not allow a 0 value; the value defaults to 1. Add three constructors. One takes three parameters for a whole number, numerator, and denominator. Another accepts two parameters for the numerator and denominator; when this constructor is used, the whole number value is 0. The last constructor is parameterless; it sets the whole number and numerator to 0 and the denominator to 1. (After construction, Fractions do not have to be reduced to proper form. For example, even though 3/9 could be reduced to 1/3, your constructors do not have to perform this task.) Add a Reduce() method that reduces a Fraction if it is in improper form. For example, 2/4 should be reduced to 1/2. Add an operator+() method that adds two Fractions. To add two fractions, first eliminate any whole number part of the value. For example, 2 1/4 becomes 9/4 and 1 3/5 becomes 8/5. Find a common denominator and convert the fractions to it. For example, when adding 9/4 and 8/5, you can convert them to 45/20 and 32/20. Then you can add the numerators, giving 77/20. Finally, call the Reduce() method to reduce the result, restoring any whole number value so the fractional part of the number is less than 1. For example, 77/20 becomes 3 17/20. Include a function that returns a string that contains a Fraction in the usual display format—the whole number, a space, the numerator, a slash (D, and a denominator. When the whole number is 0, just the Fraction part of the value should be displayed (for example, 1/2 instead of 0 1/2). If the numerator is 0, just the whole number should be displayed (for example, 2 instead of 2 0/3). b. Add an operator*() method to the Fraction class created in Exercise 11a so that it correctly multiplies two Fractions. The result should be in proper, reduced format. Demonstrate that the method works correctly in a program named FractionDemo2. c. Write a program named FractionDem03 that includes an array of four Fractions. Prompt the user for values for each. Display every possible combination of addition results and every possible combination of multiplication results for each Fraction pair (that is, each type will have 16 results).
