    Default Password Program Not Working Correctly

    So I just started learning Java, and I'm writing a program that is supposed to ask the user for a password, then checks it with a stored variable that has the password, and if correct it states "Correct", if incorrect it states "Incorrect password, please try again" and if left blank it states "Please enter a password". I have fixed the obvious bugs, and it compiled. But the bug I'm having is it always says the password is incorrect. I'm not sure exactly what's wrong, but I think the user input isn't being stored correctly. Any help is greatly appreciated. Also, sorry if my spacing is crappy, suggestions welcome. Here's the code:

    Java Code:
    import java.util.Scanner;
    public class Password {
    	public static void main (String [] args) {
    	Scanner pass_input=new Scanner(;
    	String pass;
    	System.out.println("Enter Password:");
    	pass =;
    	if (pass=="lulz") {
    	else if (pass=="") {
    		System.out.println("Please enter a password.");
    	else {
    		System.out.println("Incorrect password. Please try again");

    Never compare two Strings for equality with the == operator; use the String.equals( ... ) method instead.

    kind regards,
