There is no
printData method in Java SDK (that I know of), the only way to print content to the logs is using the
System.out.

Maybe, if you can show the code we can better help. I am thinking this is a member method of a class that you might have defined that "internally" calls the
System.out.println() method.
Secondly, the
return is a basic control statement that "returns" the control to the caller of this method and passes the value as a result of this method. If called without a value (as in a
void method) then it just returns the control and doesn't provide any value.
