- 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.Math: pentagonal numbers) A pentagonal number is defined as n(3n-1)/2 , for n = 1,2, . . ., and so on. Therefore, the first few numbers are 1, 5 ,12, 22, ... Write a Java program with an object class called Pentagon and a test class called testPentagon. The Pentagon object class must contain a method with the following header that calculates and return a pentagonal number: public int calcPentagonalNumber(int n) Use the formula: n(3n-1)/2 In the test class: Make use of the calcPentagonalNumber(n) method in the Pentagon object class and display the first 100 pentagonal numbers with 10 numbers on each line. NOTE: NO marks if the pentagonal number is calculated in the test class. Your solution must be an object-oriented solutionJava Overview In this task, you should try using the Scanner class to read data from the keyboard. This data should be stored in variables in your program and then printed on screen. Task You should write a class called Story that should include a main method. This programs should create a fairy tale for a child. The program is based on a completed story, but some words must be replaced with such as the user may enter. The fairy tale you are going to based on are the following: The little ant (1) There was once a small, small ant that lived with its (2) and its (3) siblings in an anthill, by a large (4) in the forest. The little ant is called (1). For the most part, (1) and his siblings used to work on carrying (5) and (6) to the stack, but today it was (7), so (1) was free. The words that are crossed out are the words that your program should ask the user for. In total, there are seven entries the user must make. The program must save these entries in separate variables and then…
- Writing Methods that Return a Value in Java In this lab, you complete a partially written Java program that includes a method that returns a value. The program is a simple calculator that prompts the user for two numbers and an operator ( +, −, *, /,or% ). The two numbers and the operator are passed to the method where the appropriate arithmetic operation is performed. The result is then returned to the main() method where the arithmetic operation and result are displayed. For example, if the user enters 3, 4, and *, the following is displayed: 3.00 * 4.00 = 12.00 The source code file provided for this lab includes the necessary variable declarations, and input and output statements. Comments are included in the file to help you write the remainder of the program. Instructions Write the Java statements as indicated by the comments.

- NOTE: JAVA language Write a program that asks the user for his first name and then prints it using a function/method called printName(). We do not expect the first name to exceed 20 letters. Then the program should print the name with a space between each character. Example: if the first name is Maryam, the :program will print Maryam -1 Maryam -2Code in C# (OOP Concept) Do a program that does the following: Ask for a number from the user in the main method o Pass thenumber to a method call it "Multiplication”. In the Method Multiplication, multiply the number by a number enteredby the user (mention that the number should be positive). Send the result back to the main and print it from the mainModify the previous program if the user enters a negative second number in the method Multiplication, do not acceptthe number and ask the user to reenter it again. . Add another method call it also Multiplication Ask for a float numberfrom the main and send it to the new Multiplication. This method should also ask for another positive number fromthe user and multiply it by the float number. Design and implement a function called "multiply" in C++ that accepttwo numbers and returns either the arithmetic multiplication or repetition of a given string a specific number of timesdepending on the data types of the argument values. The…Part 4: Methods The following is Java pseudocode. For this exercise, you can assume the input function provides an appropriate integer value. Line numbers are provided on the left. System.out.print will print the information to the same line. System.out.println will print the information and then go to the next line. // is a comment. Do not worry about public static. Code execution starts with the main method. For each method used, make sure to provide a separate table showing what the values are and how they change (i.e. tracing through the code). All variables passed in have values. Don’t worry about showing how the input() method works. 7 public static int test1(int x1, int x2){ 8 9 if(x1==0){ 10 x1=10; 11 } 12 if(x2==0){ 13 x2=10 14 } 15 16 return x1*x2; 17 } 18 19 public static int test2(int x2, int x1){ 20 return x2-x1; 21 } 22 public static int input(){…
- Rolling Dice Simulator [Java Assignment]Objective: Create a Java program that rolls two dice and displays the results. The program should have two Java classes: one for a single die and another for a pair of dice. Assignment Details: User Input: Ask the user to specify the number of sides they want on each die. Ensure that the user's input is within a reasonable range. Dice Rolling: Simulate rolling the dice using Math.random() based on the user's chosen number of sides. Display the sum of the values rolled, e.g., "5 + 3 = 8." Special Combinations: If the dice roll results in combinations of 2, 7, or 12, print special messages: "1 + 1 = 2 snake eyes!" "3 + 4 = 7 craps!" "6 + 6 = 12 box cars!" Main Method: In the main method, create a pair of dice, roll them, and display the results. Allow the user to decide whether to continue rolling the dice or exit the program. Additional Features: You are welcome to add more features or enhancements to the program if desired.…Value-returning methods must pass parameters. -True or -FalseThe purpose of a method parameter should be explained. A parameter and an argument are two different things.
