- java In this task, you need to write 2 overloaded methods findMax() that will find a maximum number in the array. First version should work with array of integers (int[]) and return int, and second method should work with an array of doubles (double[]) and return double as a result. Methods must have the same name and different parameters.Implement getEvens method Method Details getEvens public static int getEvens(int[] array, int[] result) Initializes the out parameter result with even values found in array Parameters: array - integer array result - integer array Returns: Number of even values found Throws: java.lang.IllegalArgumentException - if array or result (or both) are null, or if result's length is less than array's length. Any error message is fine (e.g., "Invalid parameters(s)")Create a class called Employee with threeattributes: Name, Salary and Id. Make constructors, getters, setters, tostring, displayand compareTo methods. Write a method qsort(e) that will accept an array ofEmployees and sort the results by ID. Write a method bsearch(e, id) that will accept asorted array of Employees and use a binary searchalgorithm to find a specific employee by Id.In your test driver create an array with 10employees. Be sure to populate that data sothat the ids are in random order. Display the array, call qsort then display it again andcall the bsearch with a valid id and an invalid id.
- Complete the following method in java that takes an array and a key(int value) that traverses the input parameter array with a nested for loop and finds the number of pairs of the numbers in the array that add up to the val(key) parameter.

CompareCarsByDescendingMPG should return a value that will cause quicksort to sort an array of cars in descending order (from largest to smallest) by mpg.CODe full java. In this assignment, you will implement a class called ArrayAndArrayList. This class includessome interesting methods for working with Arrays and ArrayLists.For example, the ArrayAndArrayList class has a “findMax” method which finds and returns themax number in a given array. For a defined array: int[] array = {1, 3, 5, 7, 9}, callingfindMax(array) will return 9.There are 4 methods that need to be implemented in the ArrayAndArrayList class:● howMany(int[] array, int element) - Counts the number of occurrences of the givenelement in the given array.● findMax(int[] array) - Finds the max number in the given array.● maxArray(int[] array) - Keeps track of every occurrence of the max number in the givenarray.● swapZero(int[] array) - Puts all of the zeros in the given array, at the end of the givenarray.Each method has been defined for you, but without the code. See the javadoc for each methodfor instructions on what the method is supposed to do and how to write the code. It…

QWERTY – If the argument is null, the length is anything other than 6, or if the element values are outside the inclusive boundof 1 to 7 throw the IllegalArgumentException with the message "Invalid parameter". Otherwise return a char array that hasinput[0] instances of 'Q', followed by input[1] instance of 'W', ....followed by input[5] instances of 'Y'. The length ofthe returned array should be the exact size needed to accommodate all the letters (no smaller or larger).2. turnTo1D – You can assume that the parameter array has at least 1 row and all rows are int array (might be an empty int array)and the parameter delta is a positive integer. The method returns a 1D array (possibly empty array) with all the values inarray that are in the range of the inclusive bound [value – delta to value +…
