Java 8 vs JavaMelody: What are the differences?

# Introduction

1. **Concurrency Model**: Java 8 introduces the CompletableFuture class which provides a more flexible and powerful way to manage asynchronous computations compared to JavaMelody.
2. **Functional Programming**: Java 8 introduced lambda expressions, functional interfaces, and the Stream API, enabling developers to write more concise and expressive code compared to JavaMelody which does not have these features.
3. **Date and Time API**: Java 8 introduced the new Date and Time API in the java.time package, which provides a more comprehensive and flexible way to manipulate dates and times compared to JavaMelody.
4. **Optional Class**: Java 8 introduced the Optional class to deal with the absence of a value, avoiding null pointer exceptions, which is not available in JavaMelody.
5. **Method References**: Java 8 introduced method references, which allow developers to refer to methods or constructors without invoking them, providing a more concise way to write code compared to JavaMelody.
6. **Default Methods**: Java 8 introduced default methods in interfaces, allowing developers to add new methods to interfaces without breaking existing implementations, a feature not present in JavaMelody.

# Summary

In Summary, Java 8 offers a more modern and feature-rich programming experience compared to JavaMelody, with enhancements in concurrency, functional programming, date and time handling, and language constructs.
