Using Java Eclipse IDE (Average an array) Write two overloaded methods that return the average of an array with the following headers: public static int average(int [] array) public static double average(double [] array) Write a test program that prompts the user to enter 10 double values, invokes this method, then displays the average value.

/*In this program you need to implement four methods with the following signatures:printArr(int[] a)add(int[] a, int[] b)subtract(int[] a, int[] b)negate(int[] a) 1. Method printArr(a) should print out all elements of a given int array in one line. 2. Method add(a, b) should take two int arrays (assume they have the same length) and return a new array each element of which will be the sum of the corresponding elements in a and b 3. Method subtract(a, b) is similar to add(), except it returns (a - b) array 4. Method negate(a)takes an int array and returns a new array in which every element is multiplied by -1. */ public class ArrayOperations{ public static void main(String[] args){ //The main only has the testing code. //You don't have to change it. int [] a = { 1, 2, 3, 4, 5}; int [] b = {10, 1, 3, 5, 7}; System.out.print("a = "); printArr(a);//Should print each element of a (in one line) System.out.print("b = ");...

Write a method which does the following:a. Ask the user to enter a size of array between 2 to 10.b. Based on the size entered, write a loop which asks the user to fill values into an integer array. Printthe array contents using Arrays.toString().c. For this integer array, write a logic that returns true if there exists a place to split the array such thatthe sum of the numbers on one side is equal to the sum of the numbers on the other. Otherwisereturn false.d. Examples:If the array is {1, 1, 1, 2, 1} then return true.If the array is {2, 1, 1, 2, 1} then return falseIf the array is {10, 10} then return true must include a try catch statement

1. Write a program that calls a method that takes a character array as a parameter (you can initialize an array in the main method) and returns the number of vowels in the array. Partial program is given below. public class CountVowels{ public static void main(String[] args){ char[] arr= System.out.print("There are "+vowels(arr)+" vowels in the array");
