Collections in JAVA

3. . ArrayList Operations:

Write Java code to perform the following operations on an ArrayList:

- Add an element to the ArrayList.

- Remove an element from a specific index.

- Check if an element exists in the ArrayList.

- Retrieve the size of the ArrayList.

- Iterate through the ArrayList and print its elements.

4. HashMap Basics:

Create a HashMap in Java and perform the following operations:

- Add key-value pairs to the HashMap.

- Retrieve the value associated with a specific key.

- Check if a key exists in the HashMap.

- Iterate through the HashMap and print its key-value pairs.

5. LinkedList Operations:

Implement a singly linked list in Java and write code for the following operations:

- Add a node to the beginning of the list.

- Add a node to the end of the list.

- Delete a node with a specific value.

- Search for a node with a specific value.

6. Stack Implementation:

Implement a basic stack using an ArrayList in Java. Write code to perform the

following stack operations:

- Push an element onto the stack.

- Pop an element from the stack.

- Check if the stack is empty.

- Peek at the top element of the stack without removing it.

7. Queue Implementation:

Implement a queue using a LinkedList in Java. Write code to perform the following

queue operations:

- Enqueue (add) an element to the queue.

- Dequeue (remove) an element from the queue.

- Check if the queue is empty.

- Retrieve the size of the queue.

8. Sorting ArrayList:

Write Java code to sort an ArrayList of integers in ascending order using the

`Collections.sort()` method.
