What is the function of third + symbol in concatenate string ?

String firstName, lastName; firstName = "David"; lastName = "Williams"; System.out.println("My name is " + firstName +" "+lastName correct me if I am wrong the first + sign concatenates "My name is" with ' first name' then the second + sign does the same for 'first name' and 'last name' string what is the use of third + sign?

+ concatenates without adding spaces, so there's one added in the middle: " " String + variable + space + another variable.

If you want to take a fixed number of inputs, I would use a for loop, then append the input of each loop to some container. I could only show you in Python unfortunately. ;) But maybe someone else will jump in...
