Write a method called swapltems to be considered within the SingleLinkedList class that takes two parameters, index1 and index2of type integer. The method swaps the data of the nodes at the given indexes. If any of the parameters indexes is invalid throwIndexOutofBoundsException.Do not call any method of class SingleLinkedList in your method.Method heading:public void swapltems(int index1, int index2)Example: index1 = 2index2 = 4Before method call:list: 5 10 12 9 11 7After method call: list:5 1011 9 12 7

I have implemented the given requirements as per the specification in Java. The code is as follows:…

We have a parking office class for an object-oriented parking management system using java Implement the following methods for our class Add equals and hashCode methods to any class used in a List. Add a method to the Parking Office to return a collection of customer ids (getCustomerIds) Add a method to the Parking Office to return a collection of permit ids (getPermitIds) Add a method to the Parking Office to return the collection of permit ids for a specific customer (getPermitIds(Customer)) The above methods are not included in the parking office class of our class diagram.

in Jave create a method work() with the follow instructions: If the work() method is passed a non-null then it must return a new List that contains some or all of the elements in data. The elements of the new List must be aliases for (not copies of) the objects in the List it is passed. If there are no sign attributes (i.e., the array is null or has 0 elements) then the work() method must return an empty List. If any of the conditions represented by the sign attribute holds for a particular element that that element must be included in the result (i.e., the conditions must be combined using a logical OR). The elements in the returned List must be in the same order they appeared in the original List (though not all elements must be in the result). public List<T> work(List<T> g){
Given main.py and an IntNode class, complete the IntList class (a linked list of IntNodes) by writing the insert_in_descending_order() method to insert new IntNodes into the IntList in descending order. Ex. If the input is: 3 4 2 5 1 6 7 9 8 the output is: 9 8 7 6 5 4 3 2 1 main.py(can not edit) from IntNode import IntNodefrom IntList import IntList if __name__ == "__main__": int_list = IntList() input_line = input() input_strings = input_line.split(' ') for num_string in input_strings: # Convert from string to integer num = int(num_string) # Insert into linked list in descending order new_node = IntNode(num) int_list.insert_in_descending_order(new_node) int_list.print_int_list() IntNode.py(can not edit) class IntNode: def __init__(self, initial_data, next = None, prev = None): self.data = initial_data self.next = next self.prev = prev IntList.py(need to edit)
Design a class called Post. This class models a StackOverflow post. It should have properties for title, description and the date/time it was created. We should be able to up-vote or down-vote a post. We should also be able to see the current vote value. In the main method, create a post, up-vote and down-vote it a few times and then display the the current vote value.
Instruction: To test the Linked List class, create a new Java class with the main method, generate Linked List using Integer and check whether all methods do what they’re supposed to do. A sample Java class with main method is provided below including output generated. If you encounter errors, note them and try to correct the codes. Post the changes in your code, if any. Additional Instruction: Linked List is a part of the Collection framework present in java.util package, however, to be able to check the complexity of Linked List operations, we can recode the data structure based on Java Documentation https://docs.oracle.com/javase/8/docs/api/java/util/LinkedList.html package com.linkedlist; public class linkedListTester { public static void main(String[] args) { ListI<Integer> list = new LinkedList<Integer>(); int n=10; for(int i=0;i<n;i++) { list.addFirst(i); } for(int…
Suppose you have created a new class: SortedLinkedList. This class is derived from LinkedList (single links). You are asked to overload the method Insert. The method Insert will no longer take in a parameter position, this is because now Insert will place the element in the correct position such that the list is always sorted. Write the C++ code for the implementation of that Insert method.
JAVA Write a METHOD named friendList that accepts a file name as a parameter and reads friend relationships from a file and stores them into a compound collection that is returned. You should create a map where each key is a person's name from the file, and the value associated with that key is a setof all friends of that person. Friendships are bi-directional: if Marty is friends with Danielle, Danielle is friends with Marty. The file contains one friend relationship per line, consisting of two names. The names are separated by a single space. You may assume that the file exists and is in a valid proper format. If a file named buddies.txt looks like this: Marty Cynthia Danielle Marty Then the call of friendList("buddies.txt") should return a map with the following contents: {Cynthia=[Marty], Danielle=[Marty], Marty:[Cynthia, Danielle]} Constraints: You may open and read the file only once. Do not re-open it or rewind the stream. You should choose an efficient solution. Choose data…
