Answer 2

Answer: here is the cod

import java.util.Locale;

import java.util.Scanner;

public class Main {

Scanner scan = new Scanner(System.in);  

 

 

 

public void showMenu() {

 System.out.println("1.Addition");

 System.out.println("2.Substraction");

 System.out.println("3.Multiplication");

 System.out.println("4.Division");

}

public double division() {

 scan.useLocale(Locale.US);  

 double a, b;

 System.out.println("Enter first value");

 a = scan.nextDouble();

 System.out.println("Enter second value");

 b = scan.nextDouble();

 double val = a / b;

 return val;

}

public double mutliplication() {

 scan.useLocale(Locale.US);

 double a, b;

 System.out.println("Enter first value");

 a = scan.nextDouble();

 System.out.println("Enter second value");

 b = scan.nextDouble();

 double val = a * b;

 return val;

}

public double substraction() {

 scan.useLocale(Locale.US);

 double a, b;

 System.out.println("Enter first value");

 a = scan.nextDouble();

 System.out.println("Enter second value");

 b = scan.nextDouble();

 double val = a - b;

 return val;

}

public double addition() {

 scan.useLocale(Locale.US);

 double a, b;

 System.out.println("Enter first value");

 a = scan.nextDouble();

 System.out.println("Enter second value");

 b = scan.nextDouble();

 double val = a + b;

 return val;

}

public static void main(String[] args) {

 SimpleCalculator calc = new SimpleCalculator();

 Scanner scan = new Scanner(System.in);

 scan.useLocale(Locale.US);

 int x;

 double score;

 calc.showMenu();

 x = scan.nextInt();

 switch (x) {

 case 1:

  score = calc.addition();

  System.out.println(score);

  break;

 case 2:

  score = calc.substraction();

  System.out.println(score);

  break;

 case 3:

  score = calc.mutliplication();

  System.out.println(score);

  break;

 case 4:

  score = calc.division();

  System.out.println(score);

  break;

 default:

  System.out.println("Wrong choice");

  break;

 }

}
