Write a java program that may pass for a Basic Calculator with a graphical user interface and OOP paradigm. Your calculator should have functions for: addition, subtraction, multiplication, division, modulo, exponent function(^). Use oop technique and create a class called calculator that provide unique method body for each problem. Thus, your class should have six different method for these (addition, subtraction, multiplication, division, modulo, exponent function(^)) and use the GUI for user interaction.

For the programming language Java

Create a UML class diagram of the application illustrating class hierarchy, collaboration, and the content of each class. There is only one class.  There is a main method that calls four methods.  I am not sure if I made the UML Class diagram correct. import java.util.Random; // import Random packageimport java.util.Scanner; // import Scanner Package public class SortArray{ // class name public static void main(String[] args) { //main method Scanner scanner = new Scanner(System.in); // creates object of the Scanner classint[] array = initializeArray(scanner); System.out.print("Array of randomly generated values: ");displayArray(array); // Prints unsorted array sortDescending(array); // sort the array in descending orderSystem.out.print("Values in desending order: ");displayArray(array); // prints the sorted array, should be in descending ordersortAscending(array); // sort the array in ascending orderSystem.out.print("Values in asending order: ");displayArray(array); // prints the…

We have a parking office class for an object-oriented parking management system using java Add (implement )a function to the Parking Office class to return a collection of customer ids (getCustomerIds) using java I have attached two class diagrams with definitions of all related classes in our system (i.e car, customer, .....).  N.B. Parking office methods in the class definition like register, getcustomer and addcharge have already been implemented, we just need an additional getcustomerID function as mentioned above Explain the code you wrote with a few words

Write a Java program that defines a Shape class having an abstract method draw(). Inherit Rectangle, Triangle, and Square classes from Shape and provide definition of the abstract method. Write a Driver class that receives type of the shape as input from the user and creates an object of the required class through polymorphism. Then the draw() method of required shape is invoked that further receives inputs from the user depending upon the type of the shape. For example to draw a square just one side length is required, for rectangle two sides are required and for triangle only one length of 90 degree side is required. Then for each draw() implementation, filled shape of asterisks (*) should be drawn on console.   Give the screen shots of output...and the program title is named as "Mubeen Aslam 18-ARID-2666"

5. Given the Java Point class (which contains two private variables x and y and constructors that allows creating a point object with known x and y values as well as other methods such as equals( ), toString( ) etc), (a). define a new class called Circle that contains private two variables: center which is a Point object from the Point class and radius which is of type double. The Circle class must have the following methods: (b). add a constructor which creates a circle object using a center point with x and y values and a radius as its parameters. (c). add a default constructor. ( (d). add an equals() method that can compare if any object is equal to a Circle object (two circle objects are equal if they have the same center point with the same radius). (e). add a toString() method that prints a Circle object with the center point and radius.

Using the class diagram in the image below, write a small report (200- 300 words) on how to create customer, car, and parking lot classes for an object-oriented parking system using java.
