What would be a simple regular expression for password check during signup?

Question

What I want to do is just check when the user is signing up that whether the password entered is at least 6 characters and has no space in it. Thats pretty much it. What would be a regex that I could use in Java Pattern Matcher classes for this purpose?

Thanks for your help guys.

Answer 1

Why do you want to use a regex?

public boolean isPasswordValid( String password )
{
    return ((password.length() >= 6) && (!password.contains(" "));
}
