Mastering Immutable Classes in Java

Dec 5, 2024 | medium.com | Brijesh Srivastava

Brijesh Srivastava·Follow4 min read·--When I think about designing robust software, one of the first things I consider is how to manage data that shouldn’t change. Immutable classes are my go-to solution. Imagine I’m building a food delivery system. Once an order is placed — containing the customer’s name, order items, and total amount — it must not change. Immutable objects ensure the data remains consistent, even when accessed by multiple threads.

Duplicate Strings and String Interning

Dec 4, 2024 | medium.com | Brijesh Srivastava

Brijesh Srivastava·Follow4 min read·--In Java, string literals like "Hello" are often reused across the program, but in practice, duplicate strings (strings containing the same sequence of characters) can exist multiple times in memory. This is inefficient because strings are immutable, and multiple copies of the same string needlessly consume memory in the heap. Imagine you are working on a large application that stores lots of similar strings.

Synchronization Vs ReentrantLock

Nov 22, 2024 | medium.com | Brijesh Srivastava

Brijesh Srivastava·Follow9 min read·--Java provides two primary ways to handle thread synchronization: the synchronized keyword and ReentrantLock. While both ensure thread safety by controlling access to critical sections, ReentrantLock offers more flexibility, such as the ability to try locking and timeout options, whereas synchronized is simpler to use but less flexible. Understanding the differences helps in choosing the right approach for your concurrency needs.
