Advantages of Lambda Expression in Java

In the previous blog, we learned about Lambda Expressions in Java Part 2. In this blog we will go through some of the benefits of Lambda Expression.

Advantage of Lambda Expression

Lambda expressions in Java, introduced in Java 8, allow for the creation of anonymous functions or methods in a succinct manner. They have various benefits that improve code readability, reusability, and flexibility:

1. Concise Syntax - Lambda expressions give a more compact and readable approach to define methods. They enable you to write the function body in a single line for simple expressions or in a block of code for more complex logic.
2. Improve Readability - Lambda expressions improve code readability by removing unneeded details. They concentrate on the real logic, making it easier to grasp the code's intent.
3. Reduced Code Size - We can greatly minimize the amount of code required to define a function by using lambda expressions. As a result, codebases are smaller and more compact, making them easier to manage and maintain.
4. Easier to Write and Use - When compared to traditional anonymous inner classes, writing and using lambda expressions is easier and more intuitive. It enables developers to focus on key functionality rather than getting bogged down in boilerplate code.
5. Flexibility in Parameter Types - Lambda expressions work seamlessly with functional interfaces, which are interfaces with a single abstract method. This simplifies the use of functional programming techniques in Java.
6. Enhanced API Libraries - The addition of lambda expressions resulted in modifications to Java's core libraries to enable functional programming paradigms. This has improved the APIs by making them more functional and providing more options for stream processing and functional operations.
7. Parallel Execution - With the Stream API, Lambda expressions may be used efficiently for parallel processing. This enables parallel execution, which improves performance for certain sorts of tasks.
8. Flexibility in Parameter Types - Lambda expressions can infer argument types, eliminating the need to specify them explicitly. This increases code flexibility while decreasing verbosity.
9. Anonymous Behavior - Lambda expressions allow you to define behavior inline, eliminating the requirement for a separate function or class. This is very beneficial when the behavior is only required in one location.
10. Encouragement for Functional Programming - Lambda expressions encourage developers to conceive in terms of functions and immutability, which promotes the functional programming style. As a result, the code is clearer, more modular, and has fewer side effects.
