Java Development Kit (JDK) 1.8, also known as Java SE 8, is a milestone release in the history of Java programming language. It was launched in March 2014 and brought several significant improvements and enhancements to the platform. Some notable features include:
1、Lambda expressions and functional interfaces: This introduced a concise syntax for writing functional code, making it easier to write parallel and concurrent programs.
2、Stream API: JDK 1.8 introduced the Stream API, allowing developers to perform operations on collections in a more declarative and expressive manner, enhancing performance and readability.
3、Nashorn JavaScript Engine: It provided a new JavaScript engine for Java, enabling developers to embed JavaScript within their applications.
4、Default methods in interfaces: Interfaces could now have default methods, allowing them to provide default implementations, which simplified implementation and promoted code reuse.
5、Date/Time API: The old Java date and time classes were replaced by the java.time package, offering better precision and improved handling of time zones.
6、Improved performance: Under the hood, numerous performance optimizations were made, including better garbage collection algorithms and enhanced JIT (Just-In-Time) compiler.
7、Enhanced security: The package manager and security features were strengthened, ensuring better protection against potential threats.
These advancements not only made Java more powerful but also helped bridge the gap between Java and other modern programming languages. JDK 1.8 continues to be widely used in various industries due to its stability, scalability, and rich ecosystem of libraries and frameworks.
