Why if statement doesn't work with splitted String?

Question

So in this code,
https://code.sololearn.com/c2uf18bX9uN2/?ref=app

I made a string "WordOne WordTwo", then splitted it with split method, then checked with it statement if one of the splitted words equals another string, and if statement doesn't work for some reason.

And if I don't use split method and just make a string array, and check if it equals to another string, it works! That's so confusing...

Answer 1

For String comparisons, use equals() method..

== opearator compares reference, while equal () method compare contents in java..

Ex: if(splitWords[0].equals("WordOne")){

Answer 2

Ok, but how the second part of code without split method is working and first one is not?

Answer 3

Because they will have same references in the string constant pool..
You can check thier hashcodes, would be same. and == operator compare references for non-primitive objects.. hope it helps..

Answer 4

Yes, that helped, thanks
