🌟 Highlights for Everyday Developers

Here are a few JEPs that stand out for day-to-day development:

• JEP 505 – Structured Concurrency (Fifth Preview)
  Simplifies concurrent programming by treating multiple tasks as a single unit of work. This improves readability, reliability, and observability of multithreaded code.

• JEP 506 – Scoped Values
  A lightweight, safe alternative to thread-local variables, ideal for passing values down call stacks, especially in structured concurrency contexts.

• JEP 507 – Primitive Types in Patterns and switch
  Makes pattern matching more powerful and expressive by supporting primitive types directly in instanceof and switch, reducing boilerplate code.

• JEP 512 – Compact Source Files and Instance Main Methods
  Great for scripting and quick prototyping! It simplifies Java class definitions by removing ceremony for small applications.

• JEP 513 – Flexible Constructor Bodies
  Gives developers more control over constructor behavior, making class construction clearer and easier to manage.
