Question

I just started learning code (Java specifically), and i’m testing out a password system where when you type the password it becomes the variable “password” and it checks to see if it equals password2, the actual password. Here’s the code:

import java.util.Scanner;

public class LogicalOperators {
    public static void main(String args[]){

        Scanner test = new Scanner(System.in);
        int age;
        int password;
        String password2;
        password2 = "Call of Duty";

        System.out.println("Please enter your age:");
        age = test.nextInt();



            if (age >=18) { 
                System.out.println("You are old enough."); 
                System.out.println("Please enter the password:");
                password = test.nextInt();
                if (password == password2) {
                    System.out.println("Welcome back!");
                }else{
                    System.out.println("The password you typed was incorrect.");
                }

            }else{
                System.out.println("You are too young."); 
            }   



    }   
}

I’m trying to check in the nested if statement whether the password I typed in matched password2, “Call of Duty”; but the problem is that it doesn’t work with strings. The title of this question is the error that comes up. Can someone please help me?

Answer 1

when comparing strings you should use equals instead of ==
So use

if(password.equals(password2){
do something
}
