Java Streams And Lambda Expressions

Java Streams and Lambda Expressions introduced in Java 8 enable developers to write more readable and expressive code while efficiently processing data.

What Is A Java Stream?

Java Streams provide a sequence of elements supporting operations without storing data.

Types Of Streams

This section covers the two primary types of streams in Java: sequential and parallel streams.

Creating Streams

This section introduces how to create Java Streams from various data sources such as Collections and Arrays.

Stream Operations

This section introduces the two categories of operations on Java Streams: intermediate and terminal operations.

Lambda Expressions In Java

Lambda expressions provide a concise way to implement functional interfaces in Java, enabling cleaner and more readable code.

Functional Interfaces

Functional interfaces are interfaces that contain exactly one abstract method, serving as the backbone for lambda expressions in Java.

Method References

Method references provide a shorthand notation for calling methods in Java, enhancing code readability.

Stream Collectors

Stream Collectors are utility classes in Java that help accumulate elements from streams into collections or perform summarization.

Stream Reduction

Stream Reduction in Java provides a way to combine elements of a stream into a single value.

Parallel Streams

Parallel streams in Java allow for concurrent processing of data, enhancing performance by utilizing multiple threads.

Best Practices

This section outlines essential best practices for using Java Streams and Lambda Expressions to ensure effective and efficient coding.
