What Java 8 Added
Java 8 was a major update adding functional programming features that make code shorter and cleaner.
Key Features
- Lambda expressions — short anonymous functions.
- Stream API — process collections in a pipeline.
- Functional interfaces — interfaces with one method (e.g. Runnable).
- Default methods — methods with a body inside interfaces.
- Optional — avoid null pointer errors.
Summary
- Java 8 added lambdas, streams, functional interfaces, default methods, Optional.
- These bring functional programming to Java for cleaner code.
Java 8 ने क्या जोड़ा
Java 8 एक बड़ा update था जिसने functional programming features जोड़े जो code छोटा और साफ बनाते हैं।
मुख्य Features
- Lambda expressions — छोटे anonymous functions।
- Stream API — collections को pipeline में process करें।
- Functional interfaces — एक method वाली interfaces (जैसे Runnable)।
- Default methods — interfaces में body वाली methods।
- Optional — null pointer errors से बचें।
सारांश
- Java 8 ने lambdas, streams, functional interfaces, default methods, Optional जोड़े।
- ये Java में functional programming लाते हैं साफ code के लिए।
