Lambda Expressions and Streams

Overview

Lambda expressions simplify functional programming in Java, and streams provide a powerful way to process collections.

Topics

• Syntax of Lambda Expressions
• Functional Interfaces
• Stream API (filter, map, reduce)
• Parallel Streams

Examples

List<String> names = Arrays.asList("Alice", "Bob", "Charlie");

names.stream()
    .filter(name -> name.startsWith("A"))
    .forEachprintln;

Runnable task = () -> System.out.println("Task executed");
task.run();
