System.out.println("begin...");
for(int i =0; i <=2; i++)

  System.out.println("cat");
  System.out.println("nip");
  System.out.println();

System.out.println("end...");

output

begin...
cat
nip

cat
nip

cat
nip

end...

if you are in a class, and having an exam, then that means you should have been trying code, practicing, etc- all that aside- it means you should have an IDE (eclipse, netbeans, etc)

in short- you could have (and still can for extra practice/combinations) coded this real quick and seen the answer

you need to expose yourself to as many code situations as possible.

edit:
the code block for output puts in some extra line breaks after "end..." it would not do extras, just one
