Streams & Lambda Expressions Overview

• No Parameter Lambda Expression: A lambda expression with no parameters that executes a single statement or block.
• One Parameter Lambda Expression: A lambda expression that takes one input parameter and returns a value.
• Multi Parameters Lambda Expression: A lambda expression that accepts multiple parameters for processing data efficiently.
• Streams Sum: Using Java Streams to calculate the sum of elements in a collection.
• Streams Max: Finding the maximum value from a stream of numbers.
• Streams Average: Computing the average of a set of numbers using streams.
• Streams Filter: Filtering elements based on conditions using Java Streams.

Java Streams and Lambda Expressions make it easier to work with collections using a functional programming approach. This set of practice questions helps you understand key concepts like writing lambda expressions, filtering data, and performing operations such as sum, max, and average using streams
