Java Collections framework: Java provides many data structures (List, Stack, Vector , Queues, Sets, and Maps) to store data and access data effectively and these data structure collectively known as Java Collections Framework. It also provides classes and interfaces for accessing and manipulating data stored in lists, sets and maps. Collection Interface supports two types of containers: Storing the collection of elements is called as Containers. Storing key value is called as Map. The operations of the collections are defined in Interfaces and implementations are defined in the classes.

1- The FloatArray class stores a dynamic array of floats and its size. It has:- A parameterized constructor that takes the array size. - An add method that adds a float at the end of the array.- Overloading for the insertion operator << to write the array to afile (ofstream)- Overloading for the extraction operator >> to read the array elements from the file (ifstream) and add them to the array.- A destructor to deallocate the array2- The SortedArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size. - An add method that adds a float at the right place in the arraysuch that the array remains sorted with every add. Don’t add to the array then sort but rather add in the right place.3- The FrontArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size. - An add method that adds a float at the front of the array.4- The PositiveArray that inherits from SortedArray. It has:- A parameterized constructor…

Unique Words (Python) It seems like we need to use linked lists. Summary Specifications:You are tasked to implement an abstract data type class which takes in a given input file called input.txt, and processes, identifies and sorts all unique word instances found in the file. Sample InputHi hello hi good bye goodbye Bye bye good say Sample OutputBye Hi bye hello hi say The input.txt file is found along with the zip folder where this instructions file also came along with. Note: you are not allowed to use pythonic lists, and its methods and functions, and string methods. However the use of the file handling methods (read readlines and readline) are allowed for this project.

Generics enable you to specify the exact type that will be stored in a collection and give you the benefits of compile-time type checking—the compiler issues error messages if you use inappropriate types in your collections. Once you specify the type stored in a generic collection, any reference you retrieve from the collection will have that type. Instructions Write a program that inserts 25 random integers from 0 to 100 in order into Java’s LinkedList object (you must use Java’s LinkedList class to get any credit for this assignment). The program must: sort the elements, then calculate the sum of the elements, and calculate the floating-point average of the elements. For this assignments make sure that your screen shot(s) show your program running and that your runtime display shows your random list, sorted list, sum of the elements, and average of the elements. You only get credit for what you demonstrate. Below is a sample screen shot. Your output doesn’t have to look…
