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

Checking if a string is empty or null in Java

Correct way to check for null or empty or string containing only spaces is like this:

if(str != null && !str.trim().isEmpty()) { /* do your stuffs here */ }
