Write a method called kthLargest that accepts an integer k and an array a as its parameters and returns the element such that k elements have greater or equal value. If k = 0, return the largest element; if k = 1, return the second-largest element, and so on. For example, if the array passed contains the values [74, 85, 102, 99, 101, 56, 84] and the integer k passed is 2, your method should return 99 because there are two values at least as large as 99 (101 and 102). Assume that 0 # k , a.length. (Hint: Consider sorting the array or a copy of the array first.)

Write a method that takes a rectangular two-dimensional array of type int. The method returns true if the sum of the even elements of the parameter array are larger than the sum of the odd elements, otherwise the method returns false. public static boolean sum(int[]0 in) Taken array Result 1 -3 17 5 -2 30 true 1 3 -1 -1 -3 -4 7 -1 10 false -1 3 -4 15

Write a static method named "bigBeforeSmall" that accepts an array of Strings as a parameter and rearranges its elements so that longer Strings appear before shorter Strings.  For example, if the following array is passed to your method: String[] numbers = { "one", "twelve", "three", "four", "fourteen", "six" }; Then after the method has been called, one acceptable ordering of the elements would be:   ["fourteen", "twelve", "three", "four", "one", "six" ] The exact order of the elements does not matter, so long as all longer Strings appear before all shorter Strings.  Another acceptable order would be:  ["fourteen", "twelve", "three", "four", "six", "one" ] Do not make any assumptions about the length of the array or the range of values it might contain.  For example, the array might contain empty Strings (length zero), or all Strings could have the same length.  You may assume that the array is not null (empty). Hint: This is actually a sorting problem.  In BubbleSort you tested pairs…

Write a method swapArrayEnds() that swaps the first and last elements of its array parameter. Ex: sortArray = {10, 20, 30, 40} becomes {40, 20, 30, 10}. The array's size may differ from 4. new code can only be added between existing code. as seen in image.

Write a static method that displays all combinations of picking two numbers from the array list: public static void combinations(ArrayList<Integer> list) Include the driver program that prompts the user to enter 10 integers and displays all combinations of picking two numbers from the array list.
