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.

Consider the following function main: int main() { int alpha[20]; int beta[20]; int matrix[10][4]; . . } a. write the definition of the function inputarray that prompts the user to input 20 numbers and stores the numbers into alpha. b. write the definition of the function doublearray that initializes the elements of beta to two times the corresponding elements in alpha. make sure that you prevent the function from modifying the elements of alpha. c. write the definition of the function copyalphabeta that stores alpha into the first five rows of matrix and beta into the last five rows of matrix. make sure that you prevent the function from modifying the elements of alpha and beta. d. write the definition of the function printarray that prints any onedimensional array of type int. print 15 elements per line. e. write a c11 program that tests the function main and the functions discussed in parts a through d. (add additional functions, such as printing a two-dimensional array, as needed.)
