In this assignment, you will implement Bubble Sort using Java arrays and methods. The following are basic requirements: 1. Implement the following functions: // Given arrayLength as argument, create an array of random integers between 0 and 100; return the created array. public static int[] createRandomArray(int arrayLength); // Given an integer array and filename, write the array to the file, with each line containing one integer in the array. public static void writeArrayToFile(int[] array, String filename) // This is the reverse of writeArrayToFile; Given the filename, read the integers (one line per integer) to an array, and return the array public static int[] readFileToArray(String filename); // Given an integer array, sort it in-place, i.e., the order of the elements will be changed so that the final array is in sorted order. public static void bubbleSort(int[] array) // The main function will handle a user's keyboard input specified in the next session public static void main(String[] args) 2. Export your project into a .jar file. Run the following command "java -jar BubbleSort.jar" it should be able to perform the following tasks based on users' keyboard input: (1) Generate an array of random integers and store it in a file (2) Read an existing file containing a list of integers (one integer per line), sort it and store the sorted array in another file. These are basic requirements. If you have a strong programming background, you are encouraged to make some modifications and add new features to make this command line app more user friendly.
