Purpose: In java, arrays are used to store multiple values on a single variable, instead of declaring separate variables for each value. In this assignment, you will practice how to use arrays with parameters in Java, and the program should prompt the user for the number of elements in the array and then the elements of the array. Taski: Write a Java program that asks the user to enter an array of integers in the main method. The program should prompt the user for the number of elements in the array and then the elements of the array. The program should then call a method named minGap that accepts the array entered by the user as a parameter and returns the minimum 'gap' between adjacent values in the array. The main method should then print the value returned by the method. The gap between two adjacent values in an array is defined as the difference in value between the first element and the second element. For example, suppose the user entered the following array of integers {1, 3, 6, 5, 12} The first gap is 2 (3 - 1), the second gap is 3 (6-3), the third gap is 1 (6-5) and the fourth gap is 7 (12 - 5). Thus, the call of minGap(array) should return 1 because that is the smallest gap in the array. If you are passed an array with fewer than 2 elements, you should return 0.
