So I'm trying to make a simple calculator, just to see if I can:
Java Code:
import java.util.Scanner;
class Calculator {
public static void main(String[] args) {
Scanner calculator = new Scanner(System.in);
System.out.println("Hello, and welcome to Calculator.");
System.out.println("Please type M for multiplication, D for division, S for addition, or A for subtraction.");
String firstAnswer = calculator.nextLine();
if (firstAnswer.equals("M")) {
System.out.println("You have selected multiplication. Please type the first number you wish to multiply.");
double multiplyOne = calculator.nextDouble();
System.out.println("Please enter your second number.");
double multiplyTwo = calculator.nextDouble();
double multiplyResult = multiplyOne * multiplyTwo;
System.out.print("Your result is ");
System.out.print(multiplyResult);
calculator.close();
System.exit(0);
} if (firstAnswer.equals("D")); {
System.out.println("You have selected division. Please type the first number you wish to divide.");
double divideOne = calculator.nextDouble();
System.out.println("Please enter your second number.");
double divideTwo = calculator.nextDouble();
double divideResult = divideOne / divideTwo;
System.out.print("Your result is ");
System.out.print(divideResult);
calculator.close();
System.exit(0);
} if (firstAnswer.equals("A")); {
System.out.println("You have selected addition. Please type the first number you wish to add.");
double addOne = calculator.nextDouble();
System.out.println("Please enter your second number.");
double addTwo = calculator.nextDouble();
double addResult = addOne + addTwo;
System.out.print("Your result is ");
System.out.print(addResult);
calculator.close();
System.exit(0);
} if (firstAnswer.equals("S")); {
System.out.println("You have selected subtraction. Please type the first number you wish to subtract.");
double subtractOne = calculator.nextDouble();
System.out.println("Please enter your second number.");
double subtractTwo = calculator.nextDouble();
double subtractResult = subtractOne - subtractTwo;
System.out.print("Your result is ");
System.out.print(subtractResult);
calculator.close();
System.exit(0);
}
}
}
(I'm probably doing something really stupid) Anyway, for some reason whenever I type anything other than M, it still sends me to division, even though there's no else. What am I doing wrong here?
