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

It does exactly what it does outside the println method, id adds to objects:

if the objects are Strings it concatenates them:

"hello" + "world" --> "helloworld"

if the objects are numbers it adds the UNLESS there's a String to the left (or at least a String with higher precedence).

2 + 4 + "hello" --> "6hello"

"hello" + 2 + 4 --> "hello24"

"hello" + (2 + 4) --> "hello6"

if the object is any thing else it will treat them as Strings using the toString() method
