Giới thiệu
Hôm nay mình sẽ share một bộ video học Java 8 từ LiveLessions. Với hơn 3 giờ học, các bạn sẽ nắm được những đặc điểm nổi bật nhất trong Java 8 là Lambda Expression và Stream.
Tóm tắt nội dung
- Cách sử dụng những đặc điểm quan trọng nhất trong Java 8: Lambda Expressions và Streams.
- Những kỹ thuật sử dụng lambda expression: method references, lambda building blocks in the java.util.function package, effectively-final local variables, the @FunctionalInterface annotation, and higher-order functions.
- Các method mới liên quan đến Stream: forEach, map, filter, reduce, etc.
- Infinite (unbounded) streams
- Parallel streams.
- Lazy evaluation and short-circuit stream operations.
- Những đặc điểm khác trong Java 8: Functional Interface và Optional class.
