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 + in arithmetic adds 2 numbers together, like this:

2 + 2 = 4

now apply the same thing to a string:

"hello " + "world!" = "hello world!"

now adding strings and variables will do this:

int number = 4;
String string = "what was the number? oh yeah: "+number;
System.out.println(string);

if all goes well you should get "what was the number? oh yeah: 4"

Java took the value of the variable and put it into the string for you, hope this helped!
