What are the main features of Java 85 that provide developers with the convenience?

When Java 8 was released two years ago, it was immediately welcomed by the industry because it greatly improved Java performance. Its unique selling point is that it takes into account every aspect of the programming language, including the JVM (Java Virtual machine) and compilers, and improves other help systems.

Java is one of the most searched programming languages. According to a recent survey published by the Tiobe Index, Java tops the top. The results of the Tiobe index are updated once a month. Its rankings are based on programmers, engineers, and programming courses and third-party vendors from around the world, using the search practices of Google, Bing, Yahoo, Wikipedia, Amazon, YouTube, and Baidu as a basis for searching for a variety of programming languages. The Tiobe index is not to compare which programming language is the best, or which code is used most. It is designed to help programmers understand whether the programming technology they have mastered is up to the curve. When you need to develop a new software in a language, programmers can refer to these indices to help them make their own decisions.

Back to the question of Java 8, what new features does it have? The 5 most important features are listed below.

1. Lambda Expressions (lambda expression)

A lambda expression is an anonymous function that is widely used in functional programming. Even Java Virtual machine-based programming languages Scala and Clojure have lambda expressions from the beginning, but until now Java does not support lambda expressions, so there is a good way to write code when programming.

With lambda expressions, developers can use functions anywhere, and it can be used as code. Prior to that, Java developers had to use anonymous template classes with Lambdas, but that made work tedious and difficult to maintain. Using lambda expressions makes it much easier to work. Developers only need to use a comma-delimited list or set of parameters, and use the symbol "-" in the body.

2. JavaScript Nashorn

Java and JavaScript are always incompatible, but Java 8 's new JVM JavaScript engine,--nashorn, can solve this problem completely.

Nashorn the SpiderMonkey and V8 in speed implementation. It also leverages the features of JAVA7, such as invokedynamic that can be executed faster, and improves the drawbacks of earlier versions of Java. More importantly, developers can now write JavaScript code directly in Java code without worrying about execution speed and any compatibility issues.

3. Date/time APIs

Another great addition to Java 8 is its new date/time APIs. It draws on Joda time and is used by developers to compensate for the lack of support. The properties of the Java API library are complex, and it's easy for developers to make mistakes. To compensate for this problem, Java 8 rewrites the entire API from scratch. Another reason to rewrite the API is that there is a design flaw in Joda. The new APIs have powerful properties and are simple to use.

4. Stream API

Another new feature in Java 8 is the stream API, which relies on the lambda syntax. It enables developers to work with collections. The lambda function and stream API help speed up the functional programming efficiency of Java and assist developers in writing more meaningful code.

The Stream API allows developers to easily use collections and manipulate them, such as calculations, filtering, and so on. In addition, lambda functions can help developers write more simple code. Just be careful not to confuse the stream API with InputStream and OutputStream.

5. Concurrent accumulators Parallel Accumulator

One of the great challenges for developers in the workplace is how to run code threads safely. Generic developers may not be able to implement thread safety correctly because there are too many situations to be aware of, including the need to update the number counters that are accessed by multiple threads.

With Java 8, developers can take advantage of the class of the parallel accumulator, which enables developers to efficiently handle counters in a thread-safe manner.

Java 8 seems to have left Java with the honor it lost in the past few years. These new features will allow developers to write high-quality code and keep Java in a competitive position in many programming languages.

In addition to the 5 major features mentioned above, Java 8 has other new features that you should learn and communicate. In Livecoding.tv, a social platform in which programmers around the world share programming live and communicate, there are many projects that have been developed using Java, some of which are Java 8. By watching the live or video of these developers, you can see how to apply these new features.
