• getLength ()–This method should ask the user to enter the rectangle's length, and then return that value as a double. • getWidth ()–This method should ask the user to enter the rectangle's width, and then return that value as a double. • getArea()–This method should accept the rectangle's length and width as arguments, and return the rectangle’s area. The area is calculated by multiplying the length by the width. • displayData )–This method should accept the rectangle's length, width, and area as arguments, and display them in an appropriate message on the screen.

Exercise 2: The intersection method computes the intersection of two rectangles- that is, the rectangle that would be formed by two overlapping rectangles if they were drawn, as shown at right. You call this method as follows: Rectangle r3 = r1.intersection (r2); Write a program IntersectionPrinter that constructs two rectangle objects, prints them as described in Exercise 1, and then prints the rectangle Intersection object that describes the intersection. Then the program should print the result of the intersection method when the rectangles do not overlap. Add a comment to your program that explains how you can tell whether the resulting rectangle is empty. The random class implements a random number generator, which produces sequences of numbers that appear to be random. To generate random integers, you construct an object of the Random class, and then apply the nextInt (50) gives you a random number between 0 and 49. Use the Random class to construct the two rectangle objects.
canMove(int x, int y, int destX, int destY, Side s): This method returns true if the player of color s can move the piece at coordinates (x,y) can move to coordinates (destX, destY) on the board in its current state. This means that here you do need to consider this piece’s interaction with other pieces on the board. Conditions for this method to return false are given in the code. public boolean canMove(int x, int y, int destX, int destY, Side s){ /* TODO write a method that checks if a piece at coordinates x,y can move to coordinates destX,destY Conditions for false: - Origin or destination coordinates are outside the board - Piece at origin is null - If source and destination coordinates are the same - Piece at origin is not of the same side as s - You can check this using piece.getSide() - Piece cannot move to the destination by piece movement rules - You should check this using Piece.canMove(destX,…
2. A pentagonal number is defined as n(3n-1)/2 for n = 1, 2, ..., etc.. Therefore, the first few numbers are 1, 5, 12, 22, ... . Write a method with the following header that returns a pentagonal number: %3D public static int getPentagonalNumber(int n) For example, getPentagonalNumber(1) returns 1 and getPentagonalNumber(2) returns 5. Write a test program that uses this method to display the first 100 pentagonal numbers with 10 numbers on each line. Numbers are separated by exactly one space.
Java Class: Fundraiser You are a fundraising distributor who needs to to pre-sell a limited number of doughnut coupon books. Each buyer can buy as many as 4 coupon books. No more than 100 coupon books can be sold. Implement a program called Fundraiser that prompts the user for the desired number of coupon books and then displays the number of remaining coupon books. Repeat until all coupon books have been sold, and then display the total number of buyers.
java Write a program that prompts the user to enter a point (x, y) and checks whether the point is within the rectangle centered at (0, 0) with width 10 and height 5. For example, (2, 2) is inside the rectangle and (6, 4) is outside the rectangle, as shown in the Figure. (Hint: A point is in the rectangle if its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its vertical distance to (0, 0) is less than or equal to 5 / 2.) Here are sample runs of the program: Sample 1: Enter a point with two coordinates: 2 2 Point (2.0, 2.0) is in the rectangle Sample 2: Enter a point with two coordinates: 6 4 Point (6.0, 4.0) is not in the rectangle Analysis: (Describe the problem including input and output in your own words.) Design: (Describe the major steps for solving the problem.) Coding: (Go over your code step by step) Testing: (Describe how you test this program). In other words run your code with sample outputs.
The area of a rectangle can be computed using the following formula: area = width * height; Write a method that returns the area of a rectangle using the following header: public static double getArea(double width, double height) Write a main method that prompts the user to enter the width and height of a rectangle and displays its area. Input example: 1.2 3.4 Output example: The area of the rectangle is 4.08

Code the following: Language : Java Create a method called triangle that will take in three angles and tell you if you have a triangle Create an overloaded version of the triangle method that only takes in one angle and tells you if it could be a triangle create an overloaded version of the triangle method that only takes in two angles. You must check if it's possible for it to be an isosceles triangle. Don't forget to check both angles : example: angle1*2 + angle2 == 180 or angle1 +angle2*2 == 180
