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

In that context, the + operator is acting as the string concatenation operator. It acts as a different operator in the context of two integral types, where addition will be performed.

Assuming i is an integral type, it'll be converted to a String and then added on to the end of a new string beginning with "Count is: ". That new string is then printed.

ie. If i had the value 0, it'd be the same as:

"Count is: " + "0"

Which would be:

"Count is: 0"
