Persistance of whitespaces after split

Good Evening people,

I recently started working in Java (from Python).The issue occurs when I'm trying to split a string and then test some of its elements.

I checked many other answers to similar questions but nothing solved my issue.

String str = "0 0 0 0 0";
String[] splitString = str.split("\\s");

The System.out.println(splitString[0] == "0"); always outputs false !

However System.out.println(splitString[0].contains("0")); evaluates to true.

I fear that I'm doing something really stupid but I'd like to know if someone could help me here :)

Cheers,

Alex

You don't want to use `==` to compare Strings, use the method `.equals(...);`. And if you're worried that you might be missing whitespaces, use `"\\s+"` as your regex. – AntonH May 02 '14 at 22:10
Wow thanks a lot! I knew the issue wasn't anything important – Alex Koukoulas May 02 '14 at 22:11
I was looking at the split method all that time while the issue was somewhere else! – Alex Koukoulas May 02 '14 at 22:13
