# ACTIVITY: Data Structures in Java

**Research Data Structures in Java:**Search and study various data structures commonly used in Java programming.

Focus on understanding how they work, their use cases, and their time complexity (Big-O notation).

**Explain Each Data Structure:**Write a detailed explanation of each data structure you researched. Your explanation should include:

**Definition**: What the data structure is and how it works.**Key Features**: Important characteristics and behaviors of the data structure.**Use Cases**: Where and why this data structure would be used.**Time Complexity**: Analyze the performance in terms of time complexity for common operations (insert, delete, search, etc.).**Example Code**: Provide a small code snippet in Java to demonstrate how to use the data structure.

**Data Structures to Include:**Arrays

ArrayList

LinkedList

HashMap

HashSet

Stack

Queue

PriorityQueue

TreeMap

TreeSet

**Deliverables:**A detailed write-up explaining each data structure (following the points above).

Example code for each data structure in Java to show practical usage.

**Upload**Document your research and findings in a blog post on Medium.com or Hashnode.com.

Include example code snippets in your article.

Provide a link to your article for reference.
