# ACTIVITY: Data Structures in Java

1. **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).
        
2. **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.
            
3. **Data Structures to Include:**
    
    * Arrays
        
    * ArrayList
        
    * LinkedList
        
    * HashMap
        
    * HashSet
        
    * Stack
        
    * Queue
        
    * PriorityQueue
        
    * TreeMap
        
    * TreeSet
        
4. **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.
        
5. **Upload**
    
    * Document your research and findings in a blog post on [Medium.com](http://Medium.com) or [Hashnode.com](http://Hashnode.com).
        
    * Include example code snippets in your article.
        
    * Provide a link to your article for reference.
