- Write code that creates a Random object and then assigns a random integer in the range of 100 through 399 to the variable randomNumber.OOP1 - Objects, Classes, and Encapsulation Create a program that has the following method and corresponding usage. 1. PerimeterTriangle - compute the perimeter of a triangleRead the instructions below and write your code using Microsoft Visual Studio (Community version). Build your own console application with C#. Write a Rectangle class, the private data members are the length (len) and width (wid) of the rectangle, the parameterless constructor sets len and wid to 0, and the parameterized constructor sets the value of length (len) and width (wid). In addition, the class also includes common methods such as calculating the perimeter of the rectangle, calculating the area of the rectangle, obtaining the length value of the rectangle, obtaining the width value of the rectangle, and modifying the length and width values of the rectangle to the corresponding formal parameter values. Please upload your executable C# file as attachment in the system.
- You can obtain a random integer number by using the method on a Random object once you've created it.When you instantiate an object from a class, you give a name to this particular object so that your program can distinguish it from other objects you instantiate from the same class. True FalseWrite an application TestStudent that prompts for and reads a student name. It then creates a Student object. It then prompts for and reads the number of quizzes n that the student has taken. It then prompts for and reads the scores of the student in n quizzes and adds each to the totalScore of the student using addQuiz() method. Finally, the application prints the student object using the toString() method, and it also prints his quiz average. The main method must handle java.util.InputMismatchException, java.lang.IllegalArgumentException and java.lang.Unsupported OperationException.
- Java Program - GUI Number Guessing Look at the code, notice that the actionPerformed method is not complete. It just contains code that will print to the console when buttons are pressed. Make the following modifications to the code. When the Higher button is pressed invoke this.guesser.higher(), and then put the new guess into the this.guessField When the Lower button is pressed invoke this.guesser.lower() and then put the new guess into the this.guessField When the Reset button is pressed, invoke this.guesser.reset() and then put the new guess into the ghis.guessField When the Correct button is pressed, exit the app using System.exit(0). Wrap the invocation of lower() and higher() in try catch blocks that catch NumberGuesserIllegalStateExceptions. Show a JOptionPane that alerts the user that you are onto their schemes. Change the guessing algorithm from random-guess to binary search. You can do this by changing the object created for the guesser to a plain old NumberGuesser. It…A method that changes the state of an object is called a(n)a) stator b) mutator c) constructor d) changorOOP1 - Objects, Classes, and Encapsulation Create a program that has the following method and corresponding usage. 1.

- Create an object prototype called Gradebook that will pass an array of grades for a student as a parameter. - Create a boolean in Gradebook madeHonourRoll that will check whether or not the student has made honour roll - Create a function within Gradebook, that will calculate the average of the grades passed - Create a function outside of Gradebook, that will check if the grades are over an 80% average. Return madeHonourRoll as true if the student has made over 80% average. - Create a function outside Gradebook, called toString(), that will output to console whether or not the student has made the honour roll.Create a class Fraction with two integer final fields: numeratorand denominator. Its constructor creates fractions when given valuesfor both, but it has to avoid fractions with null denominators by throwing aNullDenominatorExceptioncreate an array of "Opinion" objects called "poll" that will represent five students opinions of a class.
