Easy way to assign a word to a string using a scanner?

Question

I have a problem. If I assign a word to a string directly (by doing s="pass"), the code works the way I want. But if I try to assign it use a scanner, it seems to just skip over the if statement. I'm obviously new to java, could someone please try to help me?

import java.util.Scanner;

public class main{
  public static void main(String[] args){
    Scanner scan = new Scanner(System.in);

    String s;
    s=scan.next();

    if(s=="pass"){
        System.out.println("CORRECT");
    }
    else{
        System.out.println("INCORRECT");
    }
  }
}

I have imported the Scanner properly.

Here == will compare the references not the content.

To compare the content you need to use

.equals()    //If case is important

.equalsIgnorecase()  //If case is not important

But as your question says way to assign string is you can use = operator

The String.equals() method compares the contents of the string, whereas the == operator checks to see whether or not the objects are equal.

Change

if(s=="pass"){
        System.out.println("CORRECT");
    }

to

if(s.equals("pass")){
        System.out.println("CORRECT");
    }
