Meaning of + symbol with Strings in Java println statement

Question

I\'m new to Java. What does the below mean?

(addition) + sign in println

System.out.println ("Count is: " + i);

Answer 1

The + sign in the context of strings is the concatenation operator. It joins two strings together.

E.g.

String str = "hello" + "world";

would result in a String object called str, with a value of "helloworld".
