Your task:
Remove any word that does not start with a capital letter. For instance, for the input text of "Hello, 2022 world!", we should get "Hello, 2022 !".
Can you implement the Student class using the concepts of encapsulation? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first.
You are given a Student class in the editor. Your task is to add two fields:
● String name
● String rollNumber
and provide getter/setters for these fields:
● getName
● setName
● getRollNumber ● setRollNumber
Implement this class according to the rules of encapsulation.
Input #
Checking all fields and getters/setters
Output #
Expecting perfectly defined fields and getter/setters.
There is no need to add constructors in this class.
You are to implement removeHead, and removeTail and you also have to create the following functions (for visual purposes of the detail explanation, header and trailer sentinels are described as h and t respectively): IMPORTANT NOTE: For all the methods that has the pos parameter i.e. addAt, removeAt, move, make sure to access that specified position from whichever is nearer - the head or the tail - similar to what we have done in the get method.
Example DoublyLinkedList: h <-> 10 <-> 30 <-> 40 <-> 50 <-> t
int add(int num)
This will add the element num into the last element of the linked list and return the position of the newly-added element. In the above example, having add(60) will return 5 as it is the fifth position in the list.
int remove(int num)
This will remove the first instance of the element and return the position of the removed element. In the above example, having remove(40) will return 3 as 40 was the third element in the linked list…

The language used is Java.arrow_forwardFor the first part of this lab, copy your working ArrayStringList code into the GenericArrayList class.(already in the code) Then, modify the class so that it can store any type someone asks for, instead of only Strings. You shouldn't have to change any of the actual logic in your class to accomplish this, only type declarations (i.e. the types of parameters, return types, etc.) Note: In doing so, you may end up needing to write something like this (where T is a generic type): T[] newData = new T[capacity]; ...and you will find this causes a compiler error. This is because Java dislikes creating new objects of a generic type. In order to get around this error, you can write the line like this instead: T[] new Data = (T[]) new Object[capacity] This creates an array of regular Objects which are then cast to the generic type. It works and it doesn't anger the Java compiler. How amazing! Once you're done, screenshot or save your code for checkin later. For the second part of the lab,…arrow_forward

- Please help me create a cave class for a Hunt the Wumpus game (in java). 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.
