Recap - If Else

Part of the Fundamentals section of Coddy's Java journey — lesson 31 of 73.

Challenge

Beginner

You are given a code which gets as input two numbers n1 and n2 and a single char string op.

Note: we will learn in next lessons how to get input from the user, currently just don't touch the three first lines.

The possible values for op are +, -, / and *

Your task is to set the variable result based on the conditions:

if op is +, set result with n1 + n2.
if op is -, set result with n1 - n2.
if op is /, set result with n1 / n2.
if op is *, set result with n1 * n2.

Important: In Java, strings cannot be compared with ==. To compare a string, use the .equals() method instead. For example, to check if op is +, write: op.equals("+")

Try it yourself

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in); // Don't change this line
        int n1 = scanner.nextInt(); // Don't change this line
        int n2 = scanner.nextInt(); // Don't change this line
        scanner.nextLine(); // Don't change this line
        String op = scanner.nextLine(); // Don't change this line
        
        // Write your code below
        double result = 0;
        
        
        
        System.out.println(result);
    }
}
