Java flows provide a functional approach to process data collections. Introduced into Java 8They allow sequential and parallel execution of operations.

• Laziness: Operations on flows are not carried out as long as an terminal operation is invoked.
• Functional: Use lambda expressions.
• Pipeline: Intermediate operations refer a flow, allowing a method chaining.
• Parallelism: Supports parallel flows for simultaneous treatment.

1. Source: Create a flow from a collection, a table or an E / S channel.
2. Intermediate operations: Transformations like filter,, mapetc.
3. Terminal operations: Actions like collect,, forEachetc.

Example

import java.util.stream.*;
import java.util.*;
public class StreamCreation {
public static void main(String[] args) {
// From a Collection
List<String> names = Arrays.asList("Alice", "Bob", "Charlie")…
