Problem No. 2  Write a Java class called ContainsInRange. This class defines a method called contains(), which takes as parameters an integer array a, an integer x, an int called start, as well as an int called end, and returns a boolean which is true if and only if x occurs in a at a position which is greater than or equal to start, and less than end. You must validate that start is less than or equal to end, and that both start and end are greater than or equal to 0, and less than or equal to a.length. Repeat the operation often. (please put also the code that the user can enter a value. Thank you)

Task 3: Implement method setup in PE1 class. The description of what is wanted is given in the starter code.   public class PE1 { MazedogMaze;  /** * This method sets up the maze using the given input argument * @param maze is a maze that is used to construct the dogMaze */     publicvoidsetup(String[][]maze){ /* insert your code here to create the dogMaze  * using the input argument.  */   }     /** * This method returns true if the number of  * gates in dogMaze >= 2.  * @return it returns true, if enough gate exists (at least 2), otherwise false. */ publicbooleanenoughGate(){ // insert your code here.

In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…

Write all the code within the main method in the Test Truck class below. Implement the following functionality.  a) Constructs two truck objects: one with any make and model you                  choose and the second object with gas tank capacity 10.  b) If an exception occurs, print the stack trace.  c) Prints both truck objects that were constructed.   import java.lang.IllegalArgumentException ;  public class TestTruck {            public static void main ( String [] args )              {   heres the truck class information  A Truck can be described as having a make (string), model (string), gas tank capacity (double), and whether it has a manual transmission (or not). Include the following methods in your class definition. . An overloaded constructor which takes the make and model. This method throws an IllegalArgumentException if the make is "Jeep". An overloaded constructor which takes the gas tank capacity. This method throws an IllegalArgumentException if the capacity of the gas…

Java programming - please see attched image for initial instruction before the following below. Write a subclass of VowelSeparator that adds three additional methods and a constructor.  The class should be named VowelSeparatorAndCounter.  Here are the methods to add:  void setString(String s)  This method should replace the string stored by the object with s.  If the argument is null then the method should throw an IllegalArgumentException. (This is an unchecked exception) int getVowelCount() This method should return the number of vowels in the string.int getNonVowelCount() This method should return the number of characters in the string that are not vowels.   Write a static method that accepts an array of VowelSeparatorAndCounter objects and returns the total number of vowels contained in all of them. It should have the following signature:  public static int totalVowelCount(VowelSeparatorAndCounter[] a)

JAVA PROGRAM Chapter 7. PC #1. Rainfall Class Write a RainFall class that stores the total rainfall for each of 12 months into an array of doubles. The program should have methods that return the following: • the total rainfall for the year • the average monthly rainfall • the month with the most rain • the month with the least rain Demonstrate the class in a complete program. Main class name: RainFall (no package name)   HERE IS  A WORKING CODE, PLEASE MODIFY THIS CODE SO THE PUBLIC CLASS IS MAIN AND WERE EVER THERE IS MAIN IN THE CHANGE IT SO IT RUNS. ALSO, MAKE SURE WHEN I UPLOAD THE CODE TO HYPERGRADE IT PASSES ALL THE TEST CASES. THANK YOU   import java.util.Scanner;public class Main {        private double[] rainfall = new double[12];    public Main(double[] rainfall) {        this.rainfall = rainfall;    }    public double getTotalRainfall() {        double total = 0.0;        for(double rain : rainfall) {            total += rain;        }…
