Switch Case / Menu Driven Programs
/ Programming QuestionsQuestion 1
Write a menu driven program to accept two numbers and perform any of the fundamental operations add, subtract, multiply or division as per user’s choice. The user’s choice will be entered as an integer (1, 2, 3, 4)
java
import java.util.*;
public class Switch_calc
{
public static void main()
{
int option;
double a, b;
Scanner sc = new Scanner(System.in);
// display the menu
System.out.println("----------------------");
System.out.println(" MENU ");
System.out.println("----------------------");
System.out.println("1 to Add");
System.out.println("2 to Subtract");
System.out.println("3 to Multiply");
System.out.println("4 to Divide");
System.out.println("----------------------");
// get the user's option
System.out.println("Enter your option");
option = sc.nextInt();
// enter the numbers
System.out.println("Enter the first number");
a = sc.nextDouble();
System.out.println("Enter the second number");
b = sc.nextDouble();
// check the option entered by the user
switch (option)
{
// 1 to Add
case 1:
System.out.println("Adding " + a + " and " + b);
System.out.println("Result = " + (a + b));
break;
// 2 to subtract
case 2:
System.out.println("Subtracting " + a + " and " + b);
System.out.println("Result = " + (a - b));
break;
// 3 to Multiply
case 3:
System.out.println("Multiplying " + a + " and " + b);
System.out.println("Result = " + (a * b));
break;
// 4 to Divide
case 4:
System.out.println("Dividing " + a + " and " + b);
System.out.println("Result = " + (a / b));
break;
}
}
}

Question 2
Write a menu driven program to accept two numbers and perform any of the fundamental operations add, subtract, multiply or division as per user’s choice. The user’s choice will be entered as a character (+, -, *, /)
java
import java.util.*;
public class Calculator
{
public static void main()
{
char option;
double a, b;
Scanner sc = new Scanner(System.in);
// display the menu
System.out.println("----------------------");
System.out.println(" MENU ");
System.out.println("----------------------");
System.out.println("+ to Add");
System.out.println("- to Subtract");
System.out.println("* to Multiply");
System.out.println("/ to Divide");
System.out.println("----------------------");
// get the user's option
System.out.println("Enter your option");
option = sc.next().charAt(0);
// enter the numbers
System.out.println("Enter the first number");
a = sc.nextDouble();
System.out.println("Enter the second number");
b = sc.nextDouble();
// check the option entered by the user
switch (option)
{
// + to Add
case '+':
System.out.println("Adding " + a + " and " + b);
System.out.println("Result = " + (a + b));
break;
// - to subtract
case '-':
System.out.println("Subtracting " + a + " and " + b);
System.out.println("Result = " + (a - b));
break;
// '*' to Multiply
case '*':
System.out.println("Multiplying " + a + " and " + b);
System.out.println("Result = " + (a * b));
break;
// / to Divide
case '/':
System.out.println("Dividing " + a + " and " + b);
System.out.println("Result = " + (a / b));
break;
default:
System.out.println("Invalid Option");
}
}

Question 3
Based on the item type calculate the total amount including GST, refer to the table below
| Item Type | GST Rate % |
|---|---|
| Grocery | 5 |
| Electronic | 18 |
| Textile | 12 |
| Vehicle | 28 |
| Other | 8 |
java
import java.util.*;
public class Gst
{
public static void main()
{
// declare variables
int option;
double price, total;
Scanner sc = new Scanner(System.in);
// enter the price of the item
System.out.println("Enter the price of the item");
price = sc.nextDouble();
// display the menu
System.out.println("----------------------------");
System.out.println(" MENU ");
System.out.println("----------------------------");
System.out.println("1 for Grocery Item");
System.out.println("2 for Electronic Item");
System.out.println("3 for Textile Item");
System.out.println("4 for Vehicle Item");
System.out.println("5 for other Item");
// enter the option
System.out.println("Enter the Item Type");
option = sc.nextInt();
// check the option using a switch
switch(option)
{
case 1:
total = price + ((5*price)/100);
System.out.println("GST at 5%, Total = " + total);
break;
case 2:
total = price + ((18*price)/100);
System.out.println("GST at 18%, Total = " + total);
break;
case 3:
total = price + ((12*price)/100);
System.out.println("GST at 12%, Total = " + total);
break;
case 4:
total = price + ((28*price)/100);
System.out.println("GST at 28%, Total = " + total);
break;
case 5:
total = price + ((8*price)/100);
System.out.println("GST at 8%, Total = " + total);
break;
default:
System.out.println("Wrong Input");
break;

num2 = sc.nextFloat();
// display menu
System.out.println("Q for Quotient, R for Remainder");
// enter the option
System.out.println("Enter the option");
option = sc.next().charAt(0);
// check the option
