For Java, how do you reverse an array? For example {One, Two, Three} to {Three, Two, One}

In Java please,

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. O Type here to search DELL

Write an application that displays the strings in the provided array alphabetically in ascending order. import java.util.*; public class StringSort { publicstaticvoidmain(String[] args) { String[] values = {"mouse","dog","cat","horse","cow", "moose","tiger","lion","elephant","bird","hamster", "guinea pig","leopard","aardvark","hummingbird"}; }

Write and test a Java program that processes arrays as follows: Code a class that is called myArray consisting of the following methods: a. build and return an array of integer values (size 20 elements) b. search the array for a given element (linear search) c. Insert an element into the array after a certain element already contained in the array. This involves shifting array elements . and will require defining an array which has additional unused cells d. remove an element in an array (requires the use of searching and collapsing the array so that there are no gaps.) e. Write a method that uses a nested loop structure to create a 2-dimensional character array consisting of 6 rows and 4 columns. f. Write a method that reads the elements of the 2-D array, and displays the array contents (elements) one row per line.

in java programming answer the following: Given an array called myArr (created as ArrayList<T>) and contains the {1,2,3,4,5,6,7}. (a) what would be the contents of this array after myArr.add(10). b) write the content of myArr after myArr.add(4, 11);

Write a program in java in which we had an array and you have to find Whether this array is monotonic or not

Java ArrayLists can only be filled with reference type data, so you cannot fill them with primitive type data. How can you work around this with integers? (How can you have an ArrayList filled with integers?)

Method Details: public static java.lang.String getArrayString​(int[] array, char separator) Return a string where each array entry (except the last one) is followed by the specified separator. An empty string will be return if the array has no elements. Parameters: array - separator - Returns: stringThrows:java.lang.IllegalArgumentException - When a null array parameter is provided

Needs to br written in java: printPattern (int a) – A void method which takes user input as a parameter and generates 5 multiples of the input and stores the multiples in the array and finally prints the numbers in the following pattern (See expected output)Note: Use the array to print the numbers Enter a number : 4 Multiples of 4 are stored in an array – [4,8,12,16,20] 4 4 8 4 8 12 4 8 12 16 4 8 12 16 20

Sorting an array of batting averages would be useful only if you sort another array in the same sequence in Java. Explain.

Write a complete Java program named FindAverage that contains the following: A main method asks the user to provide the number of rows and columns for a 2-dimensional array of integers. A main method calls the getArray() method that creates the 2D array of specified size and populates it with random values from 0 to 100. A main method prints the elements of the 2D array created by getArray(). A main method calls the printAverage method that will: i. Receive the two-dimensional array as input ii. Calculate the average of elements in this array iii. Display the average on the Console. The average of all elements should be formatted as xxx.xx.
