Java 7 vs. Java 8: What's the Difference?

Edited by Huma Saeed || By Sara Rehman || Published on February 7, 2024
Java 7 introduced new features like the try-with-resources statement, while Java 8 brought major changes like lambda expressions and the Stream API for functional-style programming.

Key Differences

Java 7, released in July 2011, focused on improving the language and JVM with features like the Fork/Join framework and the try-with-resources statement. Java 8, released in March 2014, represented a significant shift in the language, introducing lambda expressions, the Stream API, and functional interfaces, which facilitated a more functional programming approach.
