This difference should be a positive number (you can use Math.abs to calculate an absolute value). If the array is empty or null, return -1. If the array has only one thing in it, return 0 (since the mode and anti-mode are the same). Definitions: The mode of an array is the element that occurs the most frequently.…
- java program Description: Write a method that return the average of an array with the following header: public static double average(double[] array); In the main method, 5 double numbers are required to be entered. Input Example: 1.2 1.2 1.3 1.3 1.35 Output Example: The average value is 1.27Method Details: public static void rotate(int[] array, boolean leftRotation, int positions) Rotates the provided array left if leftRotation is true; right otherwise. The number of positions to rotate is determined by positions. For example, rotating the array 10, 20, 7, 8 two positions to the left will update the array to 7, 8, 10, 20. Only arrays with 2 or more elements will be rotated. Hint: adding private methods that rotate an array one position to the left and one position to the right can help. Parameters: array - leftRotation - positions - Throws:java.lang.IllegalArgumentException - When a null array parameter is provided6.
