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.
Java program: Write a class called YourFirstNameLine that represents a line segment between two Points. Your Line objects should have the following method: public YourFirstNameLine (Point p1, Point P2): construct a new Line that contains the given two Points public Point getStartPoint(): return this Line’s first endpoint public Point getEndPoint(): return this Line’s second endpoint public String toString(): return a String representation of this Line, such as “[(2,3), (4,7)]" public double getSlope(): return the slope of this Line. The slope of a line between points (x1, y1) and (x2, y2) is equal to (y2-y1)/(x2-x1). If x2 equals x1, the denominator is zero and the slope is undefined, so you may return a zero in this case public void draw (Graphics g): draw a line in a DrawingPanel Write a client class called YourFirstNameLineTest with main method to test your Line class. In the main method, you need create a line object with the last four numbers of your Panther ID. For…

The lab partners of these students should all be null. TheclassPres should also be null.
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).
Slide Type Slide • Exercise # 1: Define a class Point that represents a point in 2 – D plane. The point has x and y coordinates. Define the following: • A constructor to initialize the x, y coordinates. • A method translate(self, dx,dy) to translate the point object dx , and dy units in x and y directions, respectively. • A method distanceTo (self, point2) to return the distance between the point referenced by self and point2. • getX(self) to return the value of x coordinate. • getY(self) to return the value of y coordinate Test the above class by: • Creating 2 point objects; one with (3,5) as x,y coordinates; the second with (-10,30) as x,y coordinates. • Move the first point 5.5 units in x direction and -12.5 units in y direction using translate method • Find the distance between the 2 points in their current location using distance To method A Sample output resulting from running the above test class is shown below new coordinates of point1= (8.5 , -7.5) Coordinates of point 2 =…
Purpose To review interfaces Directions Your task for this lab is to implement and test a class to store ratings of items. Your Rating class should have the following fields and methods: private double sumOfRatings - the sum of all of the ratings private int raters - the number of people who have rated an item public Rating () initialize both fields to zero public Rating (double sumofRatings, int raters) - initialize the fields to the parameter values public void addRating (double newRating) - increase the sumOfRatings by newRating and increase the number of raters by one public double getAverageRating () return the average rating; if there are no raters so far, return 0.0 public String toString() - display the average rating and how many reviews it is based on; for example, if the sum of the ratings is 32 and that is based on ratings from ten people, the toString method will return "3.2 based on 10 reviews"
Write a Circle class that has the following field: • radius: a double The class should have the following methods: no-arg constructor constructor: accepts the radius of the circle as an argument. setRadius: A mutator method for the radius field. getRadius: An accessor method for the radius field. getArea: returns the area of the circle. getDiameter: returns the diameter of the circle. getCircumference: returns the circumference of the circle Write a program that demonstrates the use of the Circle class by asking the user for the circle's radius, creating a Circle object, and then reporting the circle's area, diameter, and circumference.
