String Concatination

String firstName, lastName; firstName = "David"; lastName = "Williams"; System.out.println("My name is " + firstName +" "+lastName); this is the code that you shown there string concatenation. There is no concatenation occuring in the code you just printed that two names with a space between them. what's the actual meaning of concatenation?concatenation means joining or link together. You did nothing there like that

What the code did is it concatenated all of the strings first, then print it out as a new string. It didn't print it one by one.

the concatenation operator is +.right In java the work of separator is also done by the symbol +,where as in C comma(,) is used as the separator. I need to know ,in that code ,where the symbol '+' acts as a separator and where does it acts as string concatenation operator
