- Write a java method that receives a string containing letters of the English alphabet and then prints the three Letters with lowest frequencies. Notes: 1) Ignore letter case; Uppercase and lowercase letters are considered the same. 2) Do not use methods from the Arrays class.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?In this project, you will implement a Set class that represents a general collection of values. For this assignment, a set is generally defined as a list of values that are sorted and does not contain any duplicate values. More specifically, a set shall contain no pair of elements e1 and e2 such that e1.equals(e2) and no null elements. (in java)Requirements among all implementations there are some requirements that all implementations must maintain. • Your implementation should always reflect the definition of a set. • For simplicity, your set will be used to store Integer objects. • An ArrayList<Integer> object must be used to represent the set. • All methods that have an object parameter must be able to handle an input of null. • Methods such as Collections. the sort that automatically sorts a list may not be used. Instead, when a successful addition of an element to the Set is done, you can ensure that the elements inside the ArrayList<Integer>…
- Implement the Solver class. In doing so, you are allowed to define other classes to help you (as well as use “built-in” Java classes or the book’s classes). The point of the solver class is the solve method which takes a board/puzzle configuration represented as a 2D array of booleans and returns a char array containing a minimal sequence of moves that will lead to the solved board (all the cells around the edges being filled). The board configuration is passed in as a 5-by-5 boolean array of Booleans with exactly 16 true cells (filled) and 9 false cells (empty). The solve method then returns an array of characters representing a minimal sequence of moves that solves the puzzle. In other words, if the characters from the returned array are used in order as input to the move method on the Board object representing the initial configuration, the resulting board configuration represents the solved board. Furthermore, the solution must be minimal in the sense that there are no solutions…Use Java4. Say we wanted to get an iterator for an ArrayList and use it to loop over all items and print them to the console. What would the code look like for this? 5. Write a method signature for a method called foo that takes an array as an argument. The return type is void. 6. What is the difference between remove and clear in ArrayLists.
- 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…Implement the Solver class.

Furthermore, the solution must be minimal in the sense that there are no solutions…So how fast is the merge sort? Does it depend on the type of array? We saw with some of our previous sorts that it depended on the initial array. For example, an Insertion sort was much faster for a nearly sorted array. In this exercise, you are given the Sorter class, which contains a static mergeSort method that takes an int array and length as an input. You are also given the SortTester class which has three static methods for creating 3 different types of arrays. For this test, create one of the three arrays, then take a start time using System.currentTimeMillis(). Next, run the array through the mergeSort method in the Sorter class. Finally, record the end time and print out the results. Repeat this for the other two array types. Sample Output Random Array: ** Results Hidden ** Almost Sorted Array: ** Results Hidden ** Reverse Array: ** Results Hidden **
- For this problem, you can use all classes in the java.util package. As a genius IT/SE student, you are asked by the Ministry of Health to help them analyze the Covid sequences. In particular, given 2 Covid variants, your task is to find the longest common subsequence between them. Each Covid variant has 2 properties: code (String) and sequence (String). Both properties contain only upper case letters 'A' to 'Z'. The length of the sequence is up to 100 characters. Subsequence definition: given a string S consists of the letters s1, s2, sn in that order. If you delete zero, one, or more letters from S without changing the letters' order, the remaining string S2 is called a subsequence of S. For example: given the string "HELLO", the following strings are some of its subsequences: "HELLO", "HLO", "O", "HO", "'" (empty string). The following strings are not its subsequences: "OL", "HELLOO", "LEH". Create a type CovidVariant that contains 2 properties: code (String), and sequence (String).…Write a code in JAVA for storing information of Employee using array. Employee attributes for storing data are id (int), name (String), salary (int), department (String) and gender (char). Gender attribute can have one of two values m/M for male and f/F for female. You are required to implement following methods in your class. Prototype and description of methods is given below. Maximum 50 Employee can be stored. void add(Employee e) this method receives Employee as an argument and adds it to end of existing. In case array contains data of 50 Employee display message “Out of memory” int count( ) this methods returns total number of employee whose information is stored in array. void remove(int id) this method receives id as argument and remove employee whose id matches with the provided argument. Employee maxPaid( ) this method returns highly paid employee. If more than one employees are highly paid than return last from the given sequence. Note: No need to write main method or main…Can you help me fix my code in Java, please? I am stuck to keep going. Thank you
