You must write your own Mergesort code using Linked Lists, not ArrayLists, and you may use Linked List class available in the Java Library. You may not use any predefined sorting methods in the Java Library. One of the advantages of Mergesort algorithm is that it can easily be adapted to sort a linked list of values. This is because the algorithm retrieves the values from the two lists being merged in the order that they occur in the lists. If the lists are linked lists, then that algorithm can simply move down the list node after node. Write a program that sorts a linked list of integers using the Mergesort algorithm. The program will read the integers into a linked list, and then sort the linked list using Mergesort. This will require additional linked lists, but you should use linked lists, not arrays, for all your list storage. You may read data from the mergetest.txt file that we have provided or you may hard code that data, into one linked list. Once you have the linked list, then you begin the Mergesort algorithm.

I'm working on an assignment and i'm trying to create a to-do list in AndroidStudio. I've created the listview, edit text, switch and button, but I've hit a snag with the following: Create a new Java object to hold each todo item, it should contain a string with the text of the todo, and a boolean for if it is urgent or not. Create a List to hold all your items, and for the adapter to use for displaying them. When you click "Add", you should create a new todo item and add it to the list, clear out the text in the EditText, and call "notifyDatasetChanged()" on your adapter so it refreshes. Implement a BaseAdapter to power the ListView. In AndroidStudio, type ctrl + O (the letter ‘O’, not number zero). From the list of inherited functions, implement these ones: int getCount() - This returns the number of rows that will be in your listView. In your case, it should be the number of strings in the array list object ( return list.size() ). Object getItem(int position) – This...

THIS IS MEANT TO BE IN JAVA. What we've learned so far is variables, loops, and we just started learning some array today. The assignment is to get an integer from input, and output that integer squared, ending with newline. But i've been given some instructions that are kind of confusing to me. Please explain why and please show what the end result is. Here are some extra things i've been told to do with the small amount of code i've already written... Type 2 in the input box, then run the program so I can note that the answer is 4 Type 3 in the input box instead, run, and note the output is 6. Change the output statement to output a newline: System.out.println(userNumSquared);. Type 2 in the input box Change the program to use * rather than +, and try running with input 2 (output is 4) and 3 (output is now 9, not 6 as before). This is what I have so far... import java.util.Scanner; public class NumSquared {public static void main(String[] args) {Scanner scnr = new...

Please read the instructions carefully and keep in mind of the bolded phrases. You are NOT ALLOWED to use HashSet Create a project in NetBeans and name the project Hw06. The class will contain the following static methods: reverseS – A method that displays a string reversely on the console using the following signature: publicstaticvoidreverseS(Strings) printSub1 – print all substrings of a string (duplicated substrings are allowed, but loops are not allowed). The method signature: public static void printSub1(String s) printSub2 – print all substrings of a string (duplicated substrings are not allowed, but loops are allowed). The method signature: public static void printSub2(String s) Note: All methods should be RECURSIVE. Any predefined classes that are based on Set are not allowed. In the main method, read a string from the user and output the reversed string and substrings to the screen: Sample Run: Please input a string: abcdThe reversed string: dcbaThe substrings...

Hello! I need some help with my Java homework. Please use Eclipse Please add comments to the to program so I can understand what the code is doing and learn Create a new Eclipse project named so as to include your name (eg smith15 or jones15). In this project, create a new package with the same name as the project. In this package, write a solution to the exercise noted below. Implement the following method that returns the maximum element in an array: public static <E extends Comparable<E>> E max(E[] list) Write a test program that generates 10 random integers, invokes this method to find the max, and then displays the random integers sorted smallest to largest and then prints the value returned from the method. Max sure the the last sorted and returned value as the same!

In intellij Create a method which takes two int parameters and swaps them. Print the values before and after swapping. (Example: ‘before swap: x = 5, y = 10; after swap: x=10, y=5). ​

You have to use comment function to describe what each line does import java.io.BufferedReader; import java.io.FileNotFoundException; import java.io.FileReader; import java.io.IOException; import java.util.ArrayList; import java.util.Arrays; import java.util.List; public class PreferenceData { private final List<Student> students; private final List<Project> projects; private int[][] preferences; private static enum ReadState { STUDENT_MODE, PROJECT_MODE, PREFERENCE_MODE, UNKNOWN; }; public PreferenceData() { super(); this.students = new ArrayList<Student>(); this.projects = new ArrayList<Project>(); } public void addStudent(Student s) { this.students.add(s); } public void addStudent(String s) { this.addStudent(Student.createStudent(s)); } public void addProject(Project p) { this.projects.add(p); } public void addProject(String p) { this.addProject(Project.createProject(p)); } public void createPreferenceMatrix() { this.preferences = new...

For this problem, you are given a java code FlipAgain.java. Copy the .java file to your project folder. Open the file in your IDE. You have to edit this code to make it work. You can see that the code I have given you does not compile. So, you won’t be able to run it without fixing the code. Perform the following tasks in order. The code as given does not compile. Notice that the while loop tests if again.equals("y"), but the variable again doesn't have a value at first. Give it a value so that the code will compile and the loop will run at least once. Now that the program is working, change the loop from a while loop to a do-while loop. Make sure it still works. What happens if you delete what you added in step 1? Change the line back to just String again; Does the program still work? Why or why not? (Answer in a comment in the program.) After completing the above three tasks submit the final code, where you converted the while loop to do-while loop. FlipAgain.java ----->...

Please help me create a cave class for a Hunt the Wumpus game. You can read the rules in it's entirety of the Hunt the Wumpus game online to get a better idea of the specifications. It's an actual game. INFORMATION: The object of this game is to find and kill the Wumpus within a minimum number of moves, before you get exhausted or run out of arrows. There is only one way to ­­­win: you must discover which room the Wumpus is hiding in and kill it by shooting an arrow into that room from an adjacent room. The Cave The Wumpus lives in a cave of 30 rooms. The rooms are hexagonal. Each room has up to 3 tunnels, allowing access to 1, 2 or 3 (out of 6) adjacent rooms. The attached diagram shows the layout of rooms in the cave. The map wraps around such that rooms on the edges (white cells) have neighbors from the opposite edge (blue cells). E.g., the neighbors of room 1 are rooms 25, 26, 2, 7, 6, and 30, and you could choose to connect room 1 to any of these rooms. Observe how room 1...

Add a new Java class to your project by right clicking on the src folder in the Project pane and select New > Java Class.Enter Hours as the name for this class, and IntelliJ will add it to the files in the src folder for your project. Remember tocopy and insert the standard heading for the main method as you did for Program 2.Write a program that prompts the user to enter a number of hours, and produces the equivalent number of days as a wholenumber along with the number of hours left over. Assume that a day has exactly 24 hours. The following example showsthe format to use for your output, where the input entered by the user is underlined.Enter the number of hours: 100100 hours is 4 days, plus 4 hours.Define Variables: The number of hours will be a whole number, and we would like to obtain results as whole numbers ofdays and hours, so use the int data type to declare the variables to hold the numbers of hours input, as well as the results(the number of days and number of hours left...

Create two linkedBag objects of type string in main. Place 5 strings in the first bag and five strings in the second bag. Then your code must test if the two linkedBag objects are equal or not. You must traverse both linkedBags and test each items to see if they are the same. Then you must display a message saying the two linkedBags are the same or different. Using Java compiler.
