because this code doesn't work, help!!

Question

import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner escaner = new Scanner (System.in);
String word = escaner .nextLine();
String x = "password";
if (word==x) System.out.println("nice");
}
}

Answer 1

For string comparisons use equals() method always :

if(word.equals(x))
System.out.println("nice");

Answer 2

== checks if both Strings point to the same memory location

.equals() evaluates to the comparison of values in the Strings.
