Great point, Ian! If you’re open to using external libraries, Apache Commons has a method that simplifies this even further. The method StringUtils.isBlank() handles null, empty, and whitespace-only strings all in one go. Here’s how you can use it:

import org.apache.commons.lang3.StringUtils;  

if (StringUtils.isBlank(string)) {  
    Log.d("iftrue", "java string is null or empty");  
}

This is super useful when you also want to treat strings that only contain spaces as ‘empty.’ If that’s something you need, this method is a great option!
