| Feature |
Description |
| 1. Lambda Expressions |
Enables functional programming; write concise, inline functions |
| 2. Functional Interfaces |
Interfaces with a single abstract method; used with lambdas |
| 3. Stream API |
Efficiently process collections using map, filter, reduce, etc. |
| 4. Default & Static Methods in Interfaces |
Add methods to interfaces without breaking existing classes |
| 5. Method References |
Shorter syntax for calling methods using ClassName::methodName
|
| 6. Optional Class |
Avoid NullPointerException by explicitly handling optional values |
| 7. New Date and Time API |
Introduces java.time package for better date/time handling (immutable) |
| 8. Nashorn JavaScript Engine |
Run JavaScript code on the JVM (now deprecated in later versions) |
| 9. Collectors & Terminal Operations |
Used with Stream API for collecting results (e.g., toList()) |
| 10. Base64 Encoding/Decoding API |
Utility for encoding and decoding Base64 strings |
| 11. Repeating Annotations |
Use the same annotation type more than once on the same declaration |
| 12. Type Annotations |
Apply annotations to types (e.g., generics) |
| 13. Parallel Streams |
Process collections in parallel using multi-core processors |
