Is System.out.printf method is in syllabus for
I came across a question in Devaka's examlab software. I am not able to understand the syntax of this method.
The question was:
What would be the output of System.out.printf("12%1$s","13%1$s","14%1$s");
I have seen that output comes out to be 1213%1$s but didn't get how.
Could you please explain me?

It used to be included - you'd have to check the current syllabus to be sure. Anyway, the explanation of how format strings work is found in the
class documentation (follow the link).
