design a class named Rectangle to represent a rectangle. The class contains: ▪ Two double data fields named width and height that specify the width and height of the rectangle. The default values are 1 for both width and height. ▪ A no-arg constructor that creates a default rectangle. ▪ A constructor that creates a rectangle with the specified width and height. ▪ A method named getArea () that returns the area of this rectangle. ▪ A method named getPerimeter () that returns the perimeter. Draw the UML diagram for the class then implement the class. Write a test program that creates two Rectangle objects-one with width 4 and height 40, and the other with width 3.5 and height 35.9. Display the width, height, area, and perimeter of each rectangle in this order.

Write a class called Book having the following data members: title (String), author1 (String), author2(String), publisher (String), yearPublication (int), isbn (String), accessionNum (long), issuedTo (LibMember). Include following public methods in the class: Default constructor (without any parameters), constructor with 6 parameters (except for issuedTo – initialize issuedTo to null), set and get methods for all attributes, equals and toString. NOTE: The ISBN is a unique 13 digit number assigned by the publisher. It is like barcode. As there can be multiple copies of a book in a library, the libraries assign a unique number, called accession number, to every book in the library to keep track of the books in the library. Assume that accession number starts from 1001.
a. 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 formatâ€”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).

Please write the Java code for a Phone class that represents a mobile phone, as detailed below: It should have instance variables (attributes) for make, model, color (all stored as Strings) and capacity (stored as int: the storage capacity in GB) Please define one constructor with parameters for all those attributes. The Phone class will be immutable, except its storage capacity can be changed. So please write only one mutator method, called .setCapacity. Please write accessor methods for each instance variable. Please write a .toString() method to display all the Phone's information. Please write a .equals method to compare two Phone objects, returning true if all their attributes are the same.
