Java Q1. Write code that creates a Rectangle object myBox. Rotates myBox 45 degrees about its...
In Java programming language. For this assignment, you must write a class Rectangle and a tester RectangleTest. The Rectangle class should have only the following public methods (you can add other non-public methods): Write a constructor that creates a rectangle using the x, y coordinates of its lower left corner, its width and its height in that order. Creating a rectangle with non-positive width or height should not be allowed, although x and y are allowed to be negative. Write...
For this question you must write a java class called Rectangle and a client class called RectangleClient. The partial Rectangle class is given below. (For this assignment, you will have to submit 2 .java files: one for the Rectangle class and the other one for the RectangleClient class and 2 .class files associated with these .java files. So in total you will be submitting 4 files for part b of this assignment.) // A Rectangle stores an (x, y) coordinate...

1. Write a class called Rectangle that represents a rectangular two-dimensional region. Your Rectangle objects should have the following fields and methods: int width, int height Where width and height are the dimensions of the rectangle. Write accessor methods (i.e. getWidth(), getHeight()) that retrieve the values stored in the fields above. And mutator methods (i.e. setWidthl), setHeight() ) that change the field's values. Finally create a method called getAreal) that returns the area of the rectangle. Like we did...
Java Object Oriented Create a class that models a rectangle located in the first Cartesian quadrant. The class should store information about a rectangle such that it can be drawn in an X,Y cartesian coordinate system, including rectangles which are not aligned parallel to the X-Y axes, that is, they are oriented making an angle with the X axis. Your class should provide one constructor methods for specifying the rectangle The constructor should receive the rectangle area, the length of...
This question is about java program. Please show the output and the detail code and comment.And the output (the test mthod )must be all the true! Thank you! And the question is contain 7 parts: Question 1 Create a Shape class with the following UML specification: (All the UML "-" means private and "+" means public) +------------------------------------+ | Shape | +------------------------------------+ | - x: double | | - y: double | +------------------------------------+ | + Shape(double x, double y) | |...
Its java class pratice problem (Geometry: point in a rectangle?) 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. (Hint: A point is in the rectangle if its horizontal distance to (0, 0) is less than or equal to10 / 2 and...
A Rotating Magnet The equation of motion for a magnetic dipole moment m which rotates about its center with an angular velocity Ω is dm/dt-S2 x m. Find the electric and magnetic fields associated with this object. Neglect the displacement current in the Maxwell equations.

Making a rectangle class in java write a simple class that will represent a rectangle. Later on, we will see how to do this with graphics, but for now, we will just have to use our imaginations for the visual representations ofWthe rectangles. Instance Variables Recall that an object is constructed using a class as its blueprint. So, think about an rectangle on your monitor screen. To actually draw a rectangle on your monitor screen, we need a number of...
****Here is the assignment **** Purpose: To write an Object-Oriented application that creates a Java class with several instance variables, a constructor to initialize the instance variables, several methods to access and update the instance variables’ values, along with other methods to perform calculations. Also, write a test class that instantiates the first class and tests the class’s constructor and methods. Details: Create a class called Rectangle containing the following: Two instance variables, An instance variable of type double used...
Q1. Write a recursive function in C++ void printNumberedChars(string str, int i=0) { ... } which prints each character of the given string str on a new line, with each line numbered 1, 2, 3, …. For example calling the function with printNumberedChars("hello"); should output the following: 1. h 2. e 3. l 4. l 5. o Q2. Write a recursive function in C++ int sumArray(const int* arr, unsigned int size) { ... } which takes an array of integers,...
