Answer:
i am using Scanner class
Explanation:
import java.util.Scanner;
public class menu
{
public static void main()
{
Scanner sc = new Scanner(System.in);
System.out.println("---------------MENU--------------");
System.out.println("1. Add");
System.out.println("2. Subtract");
System.out.println("3.Multiply");
System.out.println("4. Divide");
int ch = sc.nextInt();
switch(ch)
{
case 1:
{
System.out.println("Enter first number");
int a = sc.nextInt();
System.out.println("Enter second number");
int b = sc.nextInt();
int c = a+b;
System.out.println("On adding "+a+" and "+b+" you get: "+c);
}
break;
case 2:
{
System.out.println("Enter first number");
int a = sc.nextInt();
System.out.println("Enter second number");
int b = sc.nextInt();
int c = a-b;
System.out.println("On subtracting "+a+" and "+b+" you get: "+c);
}
break;
case 3:
{
System.out.println("Enter first number");
int a = sc.nextInt();
System.out.println("Enter second number");
int b = sc.nextInt();
int c = a*b;
System.out.println("On multiplying "+a+" and "+b+" you get: "+c);
}
break;
case 4:
{
System.out.println("Enter first number");
int a = sc.nextInt();
System.out.println("Enter second number");
int b = sc.nextInt();
int c = a/b;
System.out.println("On dividing "+a+" and "+b+" you get: "+c);
}
break;
default:
{
System.out.println("Wrong choice");
}
}
}
}
