5. Java Streams and Lambda Expressions
Java 8 introduced Streams and Lambda Expressions, transforming how developers write code. The addition of Streams allows for declarative data processing, while Lambda Expressions enhance the style and brevity of functional programming. Both features significantly improve code readability and performance, making them essential for modern Java applications.

What we have learnt
- Java Streams provide a sequence of data elements to support various aggregate operations.
- Lambda expressions allow concise expressions of functional interfaces, enhancing code readability.
- Understanding functional interfaces and using them with the Stream API is crucial for effective data processing in Java.
Key Concepts
- -- Java Stream
- A sequence of elements supporting sequential and parallel aggregate operations.
- -- Lambda Expression
- A short block of code that takes parameters and returns a value, used primarily for defining inline implementation of functional interfaces.
- -- Functional Interface
- An interface with exactly one abstract method, enabling the implementation of Lambda Expressions.
- -- Stream Operations
- Comprises intermediate operations (e.g., filter, map) and terminal operations (e.g., forEach, collect) for stream processing.
- -- Parallel Stream
- A stream that splits data processing across multiple threads to achieve faster execution.
