if we have following List classes: public class LinkedList<T> { class ListNode { protected T value; protected ListNode next; public ListNode(T val, ListNode nxt) { value = val; next = nxt; } public ListNode(T val) { this(val, null); } public ListNode() { this(null, null); } } can you write the folowing methods in java: 1.Write a method for the LinkedList class called int indexOf(T val) which returns the integer index indicating the location of val in the list, or -1...
Modify the LinkedCollection class to be a SortedLinkedCollecton class and see how that effects our implementation for adding and removing items. You should reference the SortedArrayCollection class provided for how these algorithms should be implemented. What needs to change here? Is it a lot of code or not much? Include a toString method that creates and returns a string that correctly represents the current collection. Include a test driver application that demonstrates your class correctly. //--------------------------------------------------------------------------- // LinkedCollection.java // //...
Modify the library program as follows: Create a method in the LibraryMaterial class that accepts a string s as a parameter and returns true if the title of the string is equal to s. Create the same method for your library material copies. Note that it will need to be abstract in the LibraryMaterialCopy class MY CODE **************************************************************** LibraryCard: import java.util.List; import java.util.ArrayList; import java.time.LocalDate; import java.time.temporal.ChronoUnit; public class LibraryCard { private String id; private String cardholderName; ...
Using a doubly linked list as the underlying data structure, implement a list ADT that implements the ListInterface.java found in the ProgProjTwo Eclipse project starting point for this assignment. In addition to the forward iterator defined by resetIterator( ) and getNextItem( ) in ListInterface.java, implement a backwards iterator by providing resetBackIterator( ) and getPreviousItem( ) methods. As noted in the syllabus addendum, you are encouraged to develop a find( ) helper method that can support various list ADT operations. A...
Can anyone helps to create a Test.java for the following classes please?

This program has you display a pessimistic poem from a list of phrases. Next, this program has you reverse the phrases to find another more optimistic poem. Use the following algorithm. 1. You are given a list of phrases each ending with a pound sign: ‘#’. 2. Create a single String object from this list. 3. Then, split the String of phrases into an array of phrases...
Copy the program AmusementRide.java to your computer and add your own class that extends class AmusementRide. Note: AmusementRide.java contains two classes (class FerrisWheel and class RollerCoaster) that provide examples for the class you must create. Your class must include the following. Implementations for all of the abstract methods defined in abstract class AmusementRide. At least one static class variable and at least one instance variable that are not defined in abstract class AmusementRide. Override the inherited repair() method following the...
