- Please use Java as programming language Create a class whose main() holds two integer variables. Assign values to the variables. Create two methods named sum() and difference, that compute the sum and difference between the two variables respectively. Each method should perform the computation and display the results. In turn, call the two methods passing the values of the 2 variables. Create another method named product. The method should compute the product of the 2 numbers but will not display the answer. Instead, the method should return the answer to the calling main() which displays the answer. Provide your own screen display and class name.Program62.javaWrite a program that prompts for a full name (first and last) and assigns it to one string. The program then passes the full name to a void method as its sole parameter. The void method should print the first name, on one line, as many times as indicated by the length of the last name. Sample Output (image below) Program64.javaWrite a program that demonstrates method overloading by defining and calling methods that return the area of a triangle, a rectangle, or a square.Exercise 1: Write a Java application that simulates a test. The test contains at least five questions about first three lectures of this course. Each question should be a multiple-choice question with 4 options. Design a Test class. Use programmer-defined methods to implement your solution. For example: create a method to simulate the questions – simulateQuestion create a method to check the answer – checkAnswer create a method to display a random message for the user – generateMessage create a method to interact with the user - inputAnswer Display the questions using methods of JOptionPane class. Use a loop to show all the questions. For each question: If the user finds the right answer, display a random congratulatory message (“Excellent!”,”Good!”,”Keep up the good work!”, or “Nice work!”). If the user responds incorrectly, display an appropriate message and the correct answer (“No. Please try again”, “Wrong. Try once more”, “Don't give up!”, “No. Keep trying..”). Use…
- use only C# programming Write a method call CubeIt(int x, ref int cube) that takes two arguments and does not return a value. The method will cube the first argument and assign it to the second argument.In your main, call this method twice and print the value of the parameters after each method call. Write a method with the following header: static void CalculateTuitionFee(int numberOfCourses, double costPerCourse, ref double fees). This method will calculate and assign the required fees amount to the third argument. [Fees = number of courses * cost per course + 15.25].From your program Main() method, call the CalculateTuitionFee () method four times supplying different arguments each time and display the value of the third argument after each method call. Write a method that takes four parameter of type int. The method will assign the sum of the first two arguments to the third and the difference of the first two to the fourth. This method should be coded so that the calling…In Java, all arguments are transferred to a method via value call (call by value)? Choose one of the options:TrueFalseJava Program Chapter 5. PC #13. is Prime Method A prime number is a number that is evenly divisible only by itself and 1. For example, the number 5 is prime because it can be evenly divided only by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6. Write a method named isPrime, which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Demonstrate the method in a complete program. The program should ask the user to enter a number for primality test or a negative number to exit. Tip: Recall that the % operator divides one number by another, and returns the remainder of the division. In an expression such as num1 % num2, the % operator will return 0 if num1 is evenly divisible by num2. I do not want a goodbye system out in the program and it has to pass all the test cases. Test Case 1 Please enter a number to check for primality or -1 to exit:\n2ENTER2 is a prime…
- Create a method that takes a value and indicate whether it is positive or negative by a return aBoolean value.Declared as: boolean isPositive (float a)Kinetic energy is the measure of the work that an object does by virtue of its motion. It is best illustrated by the formula: KE = 0.5 mv² Create a java class that will call a method that will compute for the kinetic energy. Sample output: Enter mass of an object: 54 Enter velocity of an object: 2.87 The kinetic energy of an object is: 222.40 joules Note: 1. The result should be in 2 decimal places. 2. Apply the exception handling method. 3. SCREENSHOTS NOT ALLOWED! 4. Save your file as KineticPT.java.Retail StoreSuppose you have been consulted by a retail shop around your area to build a simple calculator. The calculator must be able to perform arithmetic operations (+, -, *, /) on integers. The program receives an expression from the user. The expression is structured as follows: integer input followed by an operator and another integer input from user prior to displaying the final result. Write a Java application that can perform the above expression. Create a method that takes two parameters and performs an arithmetic operation on the passed values. Your final output should consist of the expression and the result.
- Course Title: Modern Programming Language Please Java Language Code Question : Create a Java Project With Your name as “MJibranAKramProjectQNo1”, add a class to this Project, Class name should be MJibranAkram with 18Arid2891 as “MJibranAkram18Arid2891” (a) Add a Method to Accept names and marks of n students from user, enter the value of n from User(b) Ensure that valid data is entered. If user enters an invalid data, then appropriate message should be displayed using Message Dialog Box e.g. ‘Name cannot be a number’ or ‘Marks must be an integer value’ (c) Add another Method, to Display this data in descending order according to marks such that name of student having maximum marks should come at the top and the name of student having minimum marks should come at the bottom.java Exercise1: Write a program that takes three integer numbers from the console as inputs. For each number, the program should call a static method named isPositive() to determine if a number is positive, negative, or equal to zero. Exercise 3: The following code asks a user to enter her/his age then determines if a user is an adult or not. Trace the code, to find and solve the syntax errors. You need to identify the errors and rewrite the correct code. import java.util.Scanner; public class Ex3 { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("Enter your age:"); int age = input.nextInt(); double flag = isAdult(double age); if(flag) { System.out.println("You are an adult."); } else { System.out.println("You are not an adult."); } } public boolean isAdult(int…QUESTION 2 A prime number is a number that is evenly divisible only by itself and 1. For example, the number 5 is prime because it can be evenly divided only by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6. Write a method named isPrime, which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Demonstrate the method in a complete program. Tip: Recall that the % operator divides one number by another, and returns the remainder of the division. In an expression such as num1 % num2, the % operator will return 0 if num1 is evenly divisible by num2. QUESTION 3 Use the isPrime method that you wrote in previous question in a program that stores a list of all the prime numbers from 1 through 100 in a file. plz answer these question using java
