Question

Without using the java collections interface (i.e. do not import java.util.List, LinkedList, etc. )

Write a java program that inserts a new String element (String newItem) into a linked list before another specified item (String itemToInsertBefore).

For example if items "A", "B", "C" and "D" are in a linked list in that order and the below method is called, insertBefore("E", "C"), then "E" would be inserted before "C", making the final list to be "A", "B", "E", "C" and "D" with no nulls or blank elements or any elements missing or anything. It should work for all lenghths of linkedlists of Strings.

public Boolean insertBefore(String newItem, String itemToInsertBefore)

{

// returns true if done successfully, else returns false if itemToInsertBefore cannot be found or some other error

}

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){
Using Java programming language create a linked list named Cars with four elements: "SUV cars", "Pickup cars", "Sport cars", and "Sedan cars". Apply the following activities on the code you’ve created and provide screen shot of each result: Add a new element “Classic car” at the beginning of the linked list using iterator. Add a new element “Economic cars" after the element "Sedan Cars" using iterator. Print the LinkedList backward from the last element to the first element using hasPrevious()
The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.
Write a program that creates a linked list to represent details of students. The following details must be kept for each student: SID (for Student ID) Name Address Age Gender Your program must also display a menu to perform the following tasks: Create a linked list. Note: The method to create a linked list makes use of the method insertFirst() or insertLast() or insertOrdered() Insert new nodes to the linked list. Search for details pertaining to a particular student. Delete details of a particular student. Find number of nodes in the linked list. Display information pertaining to all students. The menu options should be as follows: Create linked list Add new student Search for a student Delete a student Find number of students Print student details Exit YOU SHOULD CREATE YOUR OWN NODE CLASS, AND YOU MUST NOT USE JAVA LINKED LIST LIBRARY.

Write a Java application CountryList. In the main method, do the following:1. Create an array list of Strings called countries.2. Add "Canada", "India", "Mexico", "Peru" in that order.3. Use the enhanced for loop to print all countries in the array list, one per line.4. Add "Spain" at index 15. Replace the element at index 2 with "Vietnam". You must use the set method.6. Replace the next to the last element with "Brazil". You must use the set method. You willlose one point if you use 3 in the set method. Do this in a manner that would replace thenext to the last element, no matter the size of the array list.7. Remove the object "Canada" Do not remove at an index. Your code should work if"Canada" was at a different location. There is a version of remove method that willremove a specific object.8. Get and print the first element followed by "***"9. Call method toString() on countries to print all elements on one line.10. Use the enhanced for loop to print all countries in the array list,…
You are going to implement a program that creates an unsorted list by using a linked list implemented by yourself. NOT allowed to use LinkedList class or any other classes that offers list functions. It is REQUIRED to use an ItemType class and a NodeType struct to solve this homework. The “data.txt” file has three lines of data 100, 110, 120, 130, 140, 150, 160 100, 130, 160 1@0, 2@3, 3@END You need to 1. create an empty unsorted list 2. add the numbers from the first line to list using putItem() function. Then print all the current keys to command line in one line using printAll(). 3. delete the numbers given by the second line in the list by using deleteItem() function. Then print all the current keys to command line in one line using printAll().. 4. putItem () the numbers in the third line of the data file to the corresponding location in the list. For example, 1@0 means adding number 1 at position 0 of the list. Then print all the current keys to command line in one…

In this assignment, you will compare the performance of ArrayList and LinkedList. More specifically, your program should measure the time to “get” and “insert” an element in an ArrayList and a LinkedList.You program should 1. Initializei. create an ArrayList of Integers and populate it with 100,000 random numbersii. create a LinkedList of Integers and populate it with 100,000 random numbers2. Measure and print the total time it takes to i. get 100,000 numbers at random positions from the ArrayList 3. Measure and print the total time it takes to i. get 100,000 numbers at random positions from the LinkedList 4. Measure and print the total time it takes to i. insert 100,000 numbers in the beginning of the ArrayList 5. Measure and print the total time it takes to i. insert 100,000 numbers in the beginning of the LinkedList 6. You must print the time in milliseconds (1 millisecond is 1/1000000 second).A sample run will be like this:Time for get in ArrayList(ms): 1Time for get in…
Java Write a java program that calls a method called removeZeroes that takes as a parameter anArrayList of integers and eliminates any occurrences of the number 0 from the list. For example,if the list stores the values [0, 4, 5, 0, 6, 0, 1] before the method is called, it should store the values [4, 5, 6, 1] after the method finishes executing. Print the ArrayList before and after the method call.
