Java Quiz on recursive calls
What will be the output of following Java quiz ?
In following Java program, two JavaQuiz objects are created and a method callAgain() is called to manipulate the value of state variable.
What will be the output when this program is executed ?
Answer
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.
So, correct answer is “2 7”.
