4. Give the class definition of ArrayChecker which has an integer array variable arr. This has 2 methods a. Constructor which take an integer parameter numElements and reads all the numElements from the user using Scanner class into arr. b. public boolean checkConsecutiveValues (int n), which checks whether arr has atleast n consecutive elements with the same values. (it is enough if it returns the first occurrence of n consecutive elements) (Write only the class definition of ArrayChecker) Eg. 1234555 5 10, if n = 4, this has four consecutive 5s, return true 10 12 111 11456666. If n-3, this has 3 consecutive 1s, return true. 10 12 111 11456666. Ifn-7, then return false

I need to have a main method in a Tester class that will:  Fill an array of type Vehicle[] of size NUM_VEHICLES with Vehicle objects. You need to generate a random number between 0 and 2. If the number is 0, add a Vehicle to the array. 1, add a Car, 2, add a Boat. The Vehicle/Car/Boat that you add must be initialized with a random efficiency between 0 and 100.0. Do this until you have added NUM_VEHICLES objects to the array How do I write it so that the array generates random numbers 0 through 2 (inclusive) and how would I then correlate those numbers to a different class object?

Provide a different implementation of ChoiceQuestion. Instead of storing the choices in an array list, the addChoice method should add the choice to the question text. For this purpose, an addLine method has been added to the Question class. Use the following files: Question.java /**   A question with a text and an answer.*/public class Question{   private String text;   private String answer;    /**      Constructs a question with empty text and empty answer.   */   public Question()    {      text = "";      answer = "";   }    /**      Sets the answer for this question.      @param correctResponse the answer   */   public void setAnswer(String correctResponse)   {      answer = correctResponse;   }    /**      Checks a given response for correctness.      @param response the response to check      @return true if the response was correct, false otherwise   */   public boolean checkAnswer(String response)   {      return response.equals(answer);   }    /**      Add a line of text to…

Write a call to Arrays static method equals with arguments arrayl and array2.
