Method x1() has code that calls method x2(). Method x2() has the following header.
public int x2() throws IOException
Which of the following statements is true?
1) Method x2(), in addition to the throws declaration, is required to also handle the exception.
2) Method x1() is not required to do anything since method x2() already declares that it throws IOException.
3) Method x1() must either catch IOException or declare that it, too, throws IOException or a superclass of IOException.
4) If an IOException is generated in the code of method x2(), the exception will be passed back to the caller as an int value.
I believe it is 3.
