Java quiz on recursive calls



For the first call to callAgain(), the “if” check is false. So, state is just incremented to 2 and printed.

For second call, the “if” condition is true, so callAgain() is invoked one more time. state becomes 6 and is returned, but not stored. When control is returned to second invocation of callAgain(), state is increased to 7.
