Java Enhancement Proposals (JEPs) are central to advancing the Java language, JVM, and core libraries, each addressing specific improvements. Here are 12 significant JEPs that have influenced or will influence Java:
1. JEP 286: Local-Variable Type Inference (Java 10)
Introduced var for local variables, allowing type inference, reducing boilerplate code, and enhancing readability.
2. JEP 305: Pattern Matching for instanceof (Java 16)
Simplified type checks by allowing pattern matching in instanceof, making code more concise by eliminating explicit casting after type checks.
3. JEP 326: Raw String Literals (Preview, never finalized)
Proposed raw string literals to handle multi-line and special character-heavy text more conveniently. Although it was never finalized, it led to JEP 355.
4. JEP 355: Text Blocks (Java 13/14)
Introduced multi-line string literals (text blocks) for cleaner representation of multi-line strings, avoiding cumbersome escape sequences.
5. JEP 359: Records (Java 14/16)
Introduced record keyword to create immutable data classes, reducing boilerplate code for classes that are mainly data carriers.
6. JEP 360: Sealed Classes (Java 15/17)
Introduced sealed classes and interfaces, allowing developers to control which classes can extend or implement them, enhancing domain modeling and security.

7. JEP 376: ZGC: Concurrent Thread-Stack Processing (Java 15)
Enhanced the Z Garbage Collector (ZGC) with concurrent processing of thread stacks, reducing pause times and improving GC performance.
8. JEP 388: Windows/AArch64 Port (Java 16)
Added support for the Windows/AArch64 architecture, expanding Java's portability across different platforms and devices.
9. JEP 391: macOS/AArch64 Port (Java 17)
Provided support for Apple’s M1 (ARM-based) chip, allowing Java applications to run natively on Apple Silicon.
10. JEP 395: Records (Standard, Java 16)
Solidified record classes as a standard feature, allowing concise declarations of immutable classes.
11. JEP 411: Deprecate the Security Manager for Removal (Java 17)
Marked the Security Manager for future removal, signaling a move toward different security solutions, as it was no longer a core part of Java's security strategy.
12. JEP 429: Scoped Values (Incubator, Java 20)
Introduced a new way to manage values with scoped lifetimes, enabling more predictable memory usage and control, particularly useful for server applications.
These JEPs have incrementally modernized Java, from improved syntax and performance to better memory management, making Java more powerful, efficient, and adaptable for modern development.
