Java ArrayList vs. Vector: When to Use Each? | Java Collection Framework

Welcome to our Java Collection Framework series! In this video, we'll explore the differences between ArrayList and Vector, two popular classes for managing dynamic arrays in Java.

**ArrayList** and **Vector** are both part of Java's Collection Framework and are used to store and manipulate collections of objects. However, they differ in several key aspects that can impact performance and usage.

**Key Points Covered in This Video:**

- **Performance Differences:** We'll discuss how ArrayList and Vector differ in terms of performance, especially concerning thread safety and synchronization.

- **Thread Safety:** Learn about Vector's inherent thread safety due to synchronized methods and how ArrayList lacks this feature, making it more suitable for single-threaded environments.

- **Usage Scenarios:** Understand the ideal use cases for ArrayList and Vector based on their capabilities and performance characteristics.

- **Memory Overhead:** Explore how Vector's synchronization adds memory overhead compared to ArrayList, which can impact overall performance in certain scenarios.

- **Best Practices:** We'll provide recommendations on when to choose ArrayList over Vector and vice versa based on specific project requirements and performance considerations.
