JDK 21 — more performant, secure, and user-friendly

The new LTS release includes 15 new and improved features to enhance performance and accelerate development by enabling programmers to write more concise and manageable code. We described every JEP in detail in our previous article, but let’s do some cherry-picking!

  • Boosted performance:
    • Virtual threads (finalized feature) enable the developers to create thousands of lightweight threads, which can be monitored and controlled like the standard application threads, bringing the performance and manageability of high-throughput applications to a new level. 
    • Generational ZGC stores young and old objects separately and collects young ones more often, thus reducing the GC and heap memory overhead. 
  • Enhanced security:
    • The new Key Encapsulation Mechanism API allows Java developers to use a modern cryptographic technique of securing symmetric keys with asymmetric or public key cryptography. KEM is a promising method for protection against quantum attacks, which may present a significant security threat in the near future. 
  • Increased convenience:
    • Unnamed patterns and variables enable the developers to substitute unnecessary type and name of record components and unused variables with the underscore character _, which increases code readability and conciseness. 
    • Record patterns are used to destructure instances of record classes and create nested patterns, enabling more declarative data processing.
