Java Strings Explained: String Pool, Immutability & Memory Management (2024)

Video Description:
In this video, we dive deep into the core concepts of how Java handles strings under the hood, focusing on JVM’s memory management. You’ll learn how the JVM creates and manages String objects, how it handles identical string values across multiple objects, and the importance of the String Pool.

Here’s what we cover:

00:00 How the JVM creates a String object: Learn about the internal mechanisms the JVM uses to create and manage String objects.

01:12 Assigning the same value to different String objects: Understand how the JVM optimizes memory by reusing objects with the same value through the String Pool.

01:44 What is the String Pool? Explore the special memory area in the JVM where string literals are stored to improve efficiency.

02:49 Is String mutable or immutable? Discover the immutable nature of String in Java and why this is important for security and performance.

03:58 What happens when we use the new keyword with the same string value? Learn the difference between creating strings with and without the new keyword and how it affects memory allocation and object creation.
If you're a Java developer or learning Java, this is a must-watch video to better understand how strings work behind the scenes in the JVM!
