- 1. Given a string of at least 3 characters as input, if the length of the string is odd return the character in the middle as a string. If the string is even return the two characters at the midpoint. public class Class1 { public static String midString(String str) { //Enter code here } } ----------- 2. Given an array of integers return the sum of the values stored in the first and last index of the array. The array will have at least 2 elements in it public class Class1 { public static int endSum(int[] values) { //Enter code here } } ----------- 3. The method takes a string as a parameter. The method prints treat if the string is candy or chocolate (of any case, such as CaNdY) Otherwise print trick import java.util.Scanner; public class Class1 { public static void trickOrTreat(String str) { //Enter code here } public static void main(String[] args) { Scanner s = new Scanner(System.in); trickOrTreat(s.nextLine()); } }In the main() method, create two arrays: String[] wordsFromFile1; String[] wordsFromFile2; Read "GettysburgAddress.txt" file and "SecondInauguralAddress.txt" file. Store their words into these two arrays. Create a method: public static void calculateTokenCounts(String[] raw, String[] tokens, int[] counts) where raw is the raw String[] array we got from getFileWords() method. String[] tokens and int[] counts are defined before calling the method. After method execution, the tokens and their counts in the raw array should be added to the the tokens and counts array. Note that the tokens and counts array may already have data in them. You can not do a fresh overwrite. Then create two arrays: String[] totalTokens int[] totalCounts use calculateTokenCounts () method to populate the latter two arrays with data from the two wordsFromFileX array. plz answer this question using java in eclipseIn the main() method, create two arrays: String[] wordsFromFile1; String[] wordsFromFile2; Read "GettysburgAddress.txt" file and "SecondInauguralAddress.txt" file.

- Let's say you have an integer array and a string array. You have to write asingle method printArray that can print all the elements of both arrays. Themethod should be able to accept both integer arrays or string arrays.(Do not use overloading, use generics).Name the file ArrayPrint.javaThe attached file, CommonFemaleNames.txt, contains the top 1000 female names in the United States. The format is integer stringwhere the integeris the popularity number (1 is most popular) and stringis a female first name. The program is to read the list of names and create an array of objects. It then sorts the array in alphabetical order. The user entersa name, which the program searches for and then reports how common that name is. The program isto use two different search algorithms, a linear search and a binary search. It reports on how many microseconds it takes to find the name using each method. Requirements 1.Each name and popularity number must be stored in a separate object. 2.The names on the list are all uppercase, but the program must find the name even if it is entered in lower case. Do this by converting the entered name to all caps. 3.It must give an appropriate message if the name entered is not on the list. 4.Both a linear and a binary search are required, for each…NO REGEX OR ANYTHING COMPLICATED PLEASE.. USE BASIC APPROACH Create a program in Python that reads data from Breakfast Menu (https://www.w3schools.com/xml/simple.xml) and builds parallel arrays for the menu items, with each array containing the menu item name, description, calories, and price, respectively. After reading the data and building the arrays, display the menu items similar to the following: name - description - calories - priceAt the bottom, display the total number of items on the menu, the average number of calories per item, and the average price per item similar to: 0 items - 0 average calories - $0.00 average price You may either read the page using Internet processing methods, or you may download and save the page and then read the data from the saved file. You must process the data using string functions (no XML libraries). must use separate subroutines/functions/methods to implement each type of processing, and include error handling for missing or invalid…
