!!!String Appending Operators
Just as you can concatenate Strings with other data objects using the [[StringAdditionOperator]], you can also use the @@+=@@ operator and the c@@concat()@@ method to append things to Strings. The @@+=@@ operator and the @@concat()@@ method work the same way, it's just a matter of which style you prefer. The two examples below illustrate both, and result in the same String:
(:div class=code :)
[@
String stringOne = "A long integer: ";
// using concat() to add a long variable to a string:
stringOne += 123456789;
@]
or
[@
String stringOne = "A long integer: ";
// using concat() to add a long variable to a string:
stringTwo.concat(123456789);
@]
In both cases, @@stringOne@@ equals "A long integer: 123456789".
