Checking if a string is empty or null in Java [duplicate]

I’m parsing HTML data. The String may be null or empty, when the word to parse does not match.

So, I wrote it like this:

if(string.equals(null) || string.equals("")){
    Log.d("iftrue", "seem to be true");
}else{
    Log.d("iffalse", "seem to be false");
}

When I delete String.equals(""), it does not work correctly.

I thought String.equals("") wasn’t correct.

How can I best check for an empty String?
