Java 23: Stream.filter Misses Performance Optimization With the release of Java 23 , developers are excited about the new features and enhancements that push the language forward. However, despite all the innovations, one key area that remains largely unchanged is the Stream.filter method in the Stream API . The filter operation is a critical tool for functional programming in Java, but it hasn’t seen the performance optimizations it desperately needs, especially when working with large datasets and parallel processing. In this blog, I will explore the existing filter implementation, why it still lags behind in performance, and what improvements could have been made in Java 23 to boost efficiency, reduce memory consumption, and scale better in modern, high-performance applications. The Current filter Implementation in Java 23 Java’s Stream API offers a declarative way to process collections, and the filter method plays a pivotal r

Today, I was going through the code of someone and found it difficult for myself to read it. And the reason behind that was too many If's and too many switch cases. Each method was written with more then 30 line of code. I wasn't sure that why he has choose Object Oriented Programming when he had to do that. Every developer who is willing to improve his programming skills he must need to keep one rule in his mind before writing code: Someone will read your code someday I think few just leave their code without method level or class level comments; so that no one get to know that who wrote that code. But, those stupids forget that subversion do this too. Anyway few of the things I think should be simple in code: Class level comments Method level comments Method should be well-commented Atomic NO to Conditional Programming I am not going to debate on comments because you can get this information from a lot of blogs. So, I will start this blog from the 4th Poi
