a). Write a method called createArray which takes two parameters a and b, and returns an array that has all integer from a to b.   Example 1: a = 6, b = 2 Array is [6, 5, 4, 3, 2] Example 2: a = 4, b = 8 Array is [4, 5, 6, 7, 8] Example 3: a = 4, b = 4 Array is [4]   b). In main method, you should ask the user to input two integers a and b. Then call method createArray and print out the array.         class Main { public static int[] createArray(int a, int b) { } public static void main(String[] args) { } }

Passing Array as Argument

An array is a data structure that holds only fixed-size data and its contents are arranged in contiguous memory slots. The primary purpose of using an array is to store data items of the identical type together. An array can stockpile any one of the following types of data: int, float, char and so forth. The elements are stored from index 0, and the difference between the two indexes of the array is termed as an offset. The array has a fixed size. Once the size is defined during array declaration, it cannot be changed later.
