Java Streams: A Modern Way to Process Data
Java Streams: A Modern Way to Process Data Introduced in Java 8, the Stream API brings a functional approach to processing collections. With streams, you can perform operations like filtering , mapping , and reducing in a concise and readable way. 🔍 What is a Stream? A Stream represents a sequence of elements and supports sequential and parallel aggregate operations. List<String> names = Arrays.asList("Alice", "Bob", "Charlie"); names.stream() .filter(name -> name.startsWith("A")) .forEach(System.out::println); Output: Alice ⚙️ Common Operations 1. filter() Filters elements based on a condition: List<Integer> nums = Arrays.asList(1, 2, 3, 4, 5); nums.stream() .filter(n -> n % 2 == 0) .forEach(System.out::println); 2. map() Transforms each element: List<String> names = Arrays.asList("Java", "Pytho...
