Thread: Need help with a simple calculator (Yes I know i'm a complete and total novice)

import java.util.Scanner;
public class startingpoint {
public static void main (String args[]){
	Scanner sc = new Scanner (System.in);
	double type,fnum, snum, answer;
 
	System.out.println("Enter one of three calculator modes, 1 (Multiplication),2 (Division), 3 (Addition). or 4(Subtraction)");
 
	type = sc.nextDouble();
 
	System.out.println("Please enter your first number now");
 
	fnum = sc.nextDouble();
 
	System.out.println("Please enter your second number now");
 
	snum = sc.nextDouble();
 
 
	if (type == 1){
		answer = fnum * snum;
	} else if (type == 2){
		answer = fnum / snum;
	}else if (type == 3){
		answer = fnum + snum;
	}else if (type == 4){
		answer = fnum + snum;
	}
 
 
	System.out.println("Your answer is"); 
	System.out.println(answer);
}
}

When I run it it says the local variable answer may not have been initialized but when I made the if-then-else statement I though that would have initialized it

Never mind I found out the problem thanks to Cornix, I forgot to add the else
