Write a full java code with input out example in OOP style that does the following: Given below is a Rectangle class consisting of an upper left coordinate and a lower right coordinate. class Rectangle { int upperLeftX; int upperLeftY; int lowerRightX; int lowerRightY; } Since the upper left coordinate and lower right coordinate comprise of points, how would you modify the definition of the Rectangle class to include these points in your class? write a complete java code to do this , not only the classes. Hint: You can create a Point class to store the x and y coordinates of the upper left and lower right points and use composition to include the upper left and lower right points inside the Rectangle class, as objects of the Point class.
a) Design and implement a Comparable Java class to represent a Rational number such as3/2. Your class will have the following methods as well as any other methods necessary (setters, getters, etc.). - A constructor that takes all parameters (numerator, denominator), - A function that returns the number of existing Rational objects, - Override the tostring method, - Methods for adding and multiplying Rational objects, - Your methods will throw exceptions if there are problems. b) Write another class to test your Rational class including the exceptions.

Write a Java class called ContainsInRange. This class defines a method called contains(), which takes as parameters an integer array a, an integer x, an int called start, as well as an int called end, and returns a boolean which is true if and only if x occurs in a at a position which is greater than or equal to start, and less than end. You must validate that start is less than or equal to end, and that both start and end are greater than or equal to 0, and less than or equal to a.length. Repeat the operation often.

Can someone help in java Create a class Hotel with member data, hotel name and category (number of stars).For the Hotel class, write the standard methods (constructors, get & set, toString ()) and the getWiFi () method, which returns the wifi address formed by the first 4 letters of the hotel name and any number (you can get it with the random number generator) .In main (), illustrate the use of the Hotel class. Create a PopulatedHotel class, successor to the Hotel with an additional ArrayList <> field on behalf of the hotel guests.For the PopulatedHotel class, write standard methods (constructors, get & set, toString ()), with the get and set methods working with separate elements of ArrayList <>. For the PopulatedHotel class, also write methods for adding and removing a guest and a method for checking that a person is staying at the hotel. In main (), illustrate the use of the PopulatedHotel class.
python pleaseWrite a class called Point that represents a point in 2D plane.- The constructor accepts the x and y dimensions of the point.- Provide a method getX that returns the x coordinate of a point, and another method getYthat returns the y coordinate of a point.- Provide a method called translate that changes the original coordinates of the point byadding a given values for x and y coordinates.- Provide a method distanceTo that calculates the distance between that point and anotherone.Use this equation to calculate the Distance math.sqrt((x2 - x1) ** 2 + (y2 - y1) ** 2))While the math is a library you should import. Where the (x1, y) is the coordinates of the first pointand (x2, y2) is the coordinates of the second pointThe output should be like this screenshot.
box1 and box2 are instances of the Box class. Attributes length, width, and height of both box1 and box2 are read from input. Then, two strings are read from input. In the Box class, define instance method print_measurements() with self and one string as parameters to output the string parameter in one line, and the following in the next line: The value of attribute length ' by ' The value of attribute width ' by ' The value of attribute height
