What's the logic behind these two outputs?

Question

System.out.println(1+1+(1+"1")); // output 211
System.out.println(1+1+(1+"1").length()); // output 4

Why isn't length() returning 3 instead?

I know it does if you place another set of parentheses before the first "1" and before the dot operator.

Answer 1

(1 + "1") evaluates to "11".

"11" is a string containing 2 characters and thus "11".length() evaluates to 2.

1 + 1 + 2 evaluates to 4.
