Difference Between Java 7 And Java 8
Java 7 introduced features like the try-with-resources statement, diamond operator, and switch statement enhancements to the language, while Java 8 brought significant changes with the introduction of lambda expressions, the Stream API for working with collections in a more functional style, the java.time package for improved date and time handling, as well as the introduction of the CompletableFuture class for asynchronous programming. Java 8 also saw the addition of default methods in interfaces, making it easier to evolve existing APIs. Overall, Java 8 introduced more modern and powerful features to the language, enabling developers to write cleaner and more concise code.

1 - Improved performance: Java 8 introduces various performance enhancements, such as improved parallel capabilities with the introduction of Streams API and optimized compiler.
2) Functional Programming: Java 8 adds support for functional programming features like lambda expressions and functional interfaces, making code more concise and readable.
3) Stream API: Java 8 introduces the Streams API, which allows developers to perform operations on sequences of elements with improved performance and ease.
4) Date and Time API: Java 8 includes a new Date and Time API which resolves issues with the existing Date and Calendar classes, offering better handling of date and time related operations.
5) Default and Static Methods in Interfaces: Java 8 allows the creation of default and static methods within interfaces, enabling better code reusability and reducing the need for abstract classes.
6) Optional Class: Java 8 introduces the Optional class, which helps avoid NullPointerException by explicitly representing optional values instead of relying on null.
7) Nashorn JavaScript Engine: Java 8 includes the Nashorn JavaScript engine, which provides better performance for executing JavaScript code within Java applications.
8) Parallel Array Sorting: Java 8 offers parallel array sorting capabilities, allowing for faster sorting of arrays using multiple threads.
