Apply the methods in the ListIterator interface to write a Java program in NetBeans that creates a LinkedList of four elements of type string, namely: Java, C#, PHP and Python. The program should then print out the elements initially in the original order, and then afterwards in reverse order using the ListIterator methods. In this case, the following is the expected output

- Read the input one line at a time and output the current line if and only if it is largerthan any other line read so far or strictly smaller than the previously outputted line. (Here,smaller is with respect to the usual order on Strings, as defined by String.compareTo()). you have to use arrylist and cant modify any code under public static void main(string[] args). example: input 138456792 output: 138492 import java.util.*; import java.io.BufferedReader; import java.io.FileReader; import java.io.FileWriter; import java.io.IOException; import java.io.InputStreamReader; import java.io.PrintWriter; import java.util.Stack; public class Part2 { /** * Your code goes here - see Part0 for an example * @param r the reader to read from * @param w the writer to write to * @throws IOException */ public static void doIt(BufferedReader r, PrintWriter w) throws IOException { /*ArrayList<String> arr = new ArrayList<>(); int count…Write a Python application that accepts a string from the user and checks it against the list below (A-Z, a-z and 0-9).}/*** Adds letterGuessed to the current String updateLetterBoard* @param usedLetterBoard* @param letterGuessed* @param first* @return updateLetterBoard with letterGuess appended. */public static String updateLetterBoard(String usedLetterBoard, char letterGuessed, boolean first) {return "";}
- Write a for loop that prints all 2-digit positive integer numbers.Write only the for loop with its block, nothing else. with javaIN JAVA Count the number of "xx" in the given string. We'll say that overlapping is allowed, so "xxx" contains 2 "xx". countXX("abcxx") → 1 countXX("xxx") → 2 countXX("xxxx") → 3/*** Adds letterGuessed to the current String updateLetterBoard* @param usedLetterBoard* @param letterGuessed* @param first* @return updateLetterBoard with letterGuess appended. */public static String updateLetterBoard(String usedLetterBoard, char letterGuessed, boolean first) {
- Why am I getting errors? Says "Index 0 out of bounds for length 0" public static void main(String[] args) { System.out.println("Enter length and width of rectangle"); for (int i=0; i < args.length; i++) { System.out.println(args[i]); } Double area= Double.parseDouble (args[0]) * Double.parseDouble (args[1]); System.out.println(" Area of rectangle is :" + String.format("%.3f", area)); } }Create an iterator that returns numbers, starting with 1, and each sequence will increase by one (returning 1,2,3,4,5 etc.):Write Java program that reads array of integers. Calculate the sum of all integers that cointain at least one digit 4. Write Java program that read array of strings. Print all strings that contain at least three characters 's'.
