Java Java Basics Using your New Tools Multiple Strings

Why doesn't he need a space in between the string and the variable?

Well, in case I didn't phase that right, here is what I mean. He doesn't need a space between readLine and the following parenthesis or between printf and the following parenthesis. For me until I inserted a space in there, javac command would show errors. For him the code works fine without them.

Hello Arthur Kharzamanov.

That issue sounds a little strange. Will you post your code here? I'd like to read it and figure out why that's happening to you.

Actually, now as I tried rewriting the code this issue is no longer there and whether with a space or not the code works fine. I guess it was some bug or misunderstanding. So I assume Java isn't sensitive to spaces? Like are these the same to Java?

  String name = console.readLine("Enter a name:  ");
  String name = console.readLine ("Enter a name:  ");

That's good you were able to resolve the issue.

My understanding is that sometimes you need spaces, and sometimes not. You definitely need them on the declarations, like if you are declaring 'name' as a string, you wouldn't be able to use 'Stringname'. Java wouldn't understand that as a String declaration. I don't think having spaces before and after the '()' typically hurts anything. I can't think of a good way to explain all the instances of when to/not to use spaces.

No get it thanks) Sometimes its obvious that a space is necessary it's just this bug through me off a little. Thank you though:)
