Question 1: In this problem, you will work with pure Java arrays whose data is of type int. You should perform steps in order since each step may affect a subsequent step: (A) Define an array reference variable named data of type int and initialize this array reference to null (2 marks) (B) Create a new array object of type int with a length of 15, and assign this new array object to the array referenc variable named data (2 marks). (C) What index values are now valid in the array named data (2 marks)? (D) What value is now stored at each index of the array named data (2 marks)
