Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which may contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods. A feature of objects is that an object's procedures can access and often modify the data fields of the object with which they are associated (objects have a notion of "this" or "self"). There is significant diversity of OOP languages, bat the most popular ones are class-based, meaning that objects are instances of classes, which typically also determine their type. Question \#1 Write a program that creates two classes - Circle and Trapezoid. For each class, provide method getters and setters, method areal that will calculate the area of the shape, and method toSiringo 0 that will display the class name. Use private data fields. The constructor of each class should set a default value for each shape. For class Circle, set the default radius to 4 inches. For class Traperoid set the default values to 15 inches for Base " a ", 5 inches for Base " b ", and 25 inches for the height (see diagram below as an example) Trapezoid Solve for arba - A=2a+bh a thin b Aane h Heigh Using the Java ArrayL ist class and the loop concept, create five objects of the given shapes above. Which object to create and load into an array depends on your random number generator between 1 to 2 . If the random number is 1 , then using your default constructor create and load a Circle object into your ArrayList. If the random number is 2, then using your default constructor create and load a Trapezoid object into your ArrayList. In your program, you are required to use Java ArrayList class to store your objects. Use the array declaration given below in your program: /Generic Arraylist with detault capacity ArrayList arrayOfShapes = new ArrayListo 0 ; 2 Using loop reiterates through your array of objects and call functions toString0 and area0) to print the class name and its area. Use Math.randown() to generate random numbers between 1 to 2
