System.out.println("4.Division");
System.out.println("Enter the option you want to perform.");
Option = br.readLine();
switch (Option)
{
case '1':
Result = Number1 + Number2;
System.out.println("The Addition of two numbers is: " + Result);
break;
case '2':
Result = Number1 - Number2;
System.out.println("The Substraction of two numbers is: " + Result);
break;
case '3':
Result = Number1 * Number2;
System.out.println("The Multiplication of two numbers is: " + Result);
break;
case '4':
Result = Number1 / Number2;
System.out.println("The Division of two numbers is: " + Result);
break;
default:
System.out.println("Invalid Option");
break;
}
}
catch (IOException ex)
{
}
}
public static void main(String[] args)throws IOException
{
Program p = new Program();
p.calculation();
}
}推荐答案
