Write a Java method named average.  The method should take an ArrayList of Integers as a parameter, compute the average of the elements in the ArrayList and return the average to the calling method.

Write a method in your ArrayUtilities class that meets the following requirements: - It should be named "counts".] - It should declare a parameter for an int array. You may assume that the array will contain only non-negative values. - It should return an int array where the value at each index is the count of how many times the index appears in the original array . For example, if the original array contained the value 10 3 times, then the value at index 10 in the count array should be 3. - Hint: the size of the array is determined by the maximum value in the original array. If the original array is empty, the count array should also be empty. A more detailed example: Given the int array [1, 2, 3, 4, 4, 1, 1, 2, 0, 6], your function would return the array [1, 3, 2, 1, 2, 0, 1]. The value at each index indicates how many times the index appears in the original array. The value at index 0 is 1 because 0 appears 1 time in the original array. The value at index 1 is 3 because 1 appears 3…

PLEASE HELP ME WITH MY JAVA HOMEWORK PLEASE PLEASE! Write a program that stores positive random integers in an array. • Get the element number(length of the array) from the user. It cannot be less than 10. And fill this array andomly. The range is up to you. No duplicate values are allowed. Display the elements. • Your job is to write a method that finds and returns the next biggest positive integer considering the biggest element in this array. • Show me your main method too. DO NOT USE ANY PRE_DEFINED METHODS IN THE JAVA API.

The editTemperatures() method takes in two parameters: integer array tempData and integer numMore. Complete editTemperatures() to create a new array called arrayCopy with the same elements as tempData, and the size increased by numMore. Ex: If the input is: 10 48 49 18 3 then the output is: 10 48 49 18 0 0 0 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35     Scannerscnr=newScanner(System.in); int[] degreesFahrenheit=newint[4]; intinput; inti;   for (i=0; i<degreesFahrenheit.length; ++i) { degreesFahrenheit[i] =scnr.nextInt(); }   // Read number of values to increase array size by input=scnr.nextInt();   degreesFahrenheit=editTemperatures(degreesFahrenheit, input);   for (i=0; i<degreesFahrenheit.length; ++i) { System.out.print(degreesFahrenheit[i] +" "); } } }

Code these three methods.

JAVA complete a method that swaps the first and second half of an array of integers. For example, if the array contains the values 1 4 9 16 25 36then after calling the method, it should contain the values16 25 36 1 4 9If the array contains an odd number of elements, leave the middle element in place. For example, 1 4 9 16 25 36 45becomes25 36 45 16 1 4 9

Write the definition of a method reverse, whose parameter is an array of chars. The method reverses the elements of the array. The method does not return a value.

Write a Java method that takes an array of type int and returns a boolean value. The method returns true if the number of positive elements in the parameter array is larger than the number of negative elements. The method returns false if any of the following conditions is satisfied: • The parameter array is of length of 0 or 1 • The number of positive elements of the parameter array is less than or equal to the number of negative elements • The number of positive elements or negative elements is equal to zero The method's header is as follows. public static boolean verify (int[] x) Sample run Result int[] x = (1, 2, 3}; verify(x); {5}; verify(x); int[] x = {1, 2, 3, -5, -1}; boolean b = verify(x); int[] x = new int[0]; verify(x); false boolean b = int[] x = boolean b = false true false boolean b = BIU A Paragraph +v

Write a program named GradeStats.java then implement the following method: public static int[] gradeStats(int[] arr) It accepts int array representing test grades for CISY432 then calculates and returns the following grade statictics: highest, lowest, average, number of grades that are greater than or equal to 70, the number of grades that are less than 70 It returns these five numbers as an int array, and the 1st element is for highest, 2nd for lowest, 3rd for average 4th element for number of grades that are greater than or equal to 70 5th for the number of grades that are less than 70 For example.
