10 reasons to fall in love with java and jvm

Java and JVM have been around for a long time, and based on this fact, some programmers have started to take a lot of things for granted. Today we will talk about the top ten reasons why "Java has become and will continue to be the leading platform for software projects"

1. High-performance JVM

Java was originally developed to "write once and run anywhere" and is powered by virtualization The machine provides an operating platform. Without a JVM, Java would have to follow in the footsteps of Ruby and Python - painfully improving its portability even further. With the emergence of the Internet of Things, a powerful virtual machine has become increasingly important.

2. Core API

The most favorite thing is the Java core API - it has been completely backwards compatible since its birth, so that we can start writing more Java applications. While there are countless additional libraries and JVM languages ​​that provide concise language levels to access multiple core API capabilities, most of them actually rely on the dominance of the Java core API. Although other languages ​​have followed suit, few have remained as stable as Java.

3. Compiler

There are many Java compilers worth admiring - convert your source code into bytecode, and then become an executable file - and due to the emergence of JIT, other literal translation programs are compared to Into the dust. And the inherently simple Java compiler allows developers to focus only on the code without paying attention to the compiler architecture.

4. Bytecode

Like the compiler, in Java bytecode, simplicity is king. It greatly reduces the chance of writing potentially incorrect code. And there is no need for third-party bytecode manipulation tools.

5. Memory model

By providing a hardware-independent memory model in the JVM, Java does not need to uninstall external libraries. This allows the language, core API, and compiler to work together to provide a stable foundation and shared state for parallel operations.

6. Open Source

When it comes to open source, Java is no exception. The special thing about Java is that it actually widely penetrates OSS concepts into its ecosystem - whether it is in mobile form or in some decisive systems in enterprises and even the world. The only other competitor is Linux.

7. Intelligent integrated development environment

With the trinity of IntelliJ IDEA, NetBeans and Eclipse in 2015, developers have a more luxurious choice when it comes to looking for free open source development environments - its The plugin suite and services are truly next level.

8. Analysis Tools

As we all know, assumptions always make people very depressed, and this is when analysis tools come into play. Developers can solve these "what if" questions through various analysis tools that have been packaged as JDK.

9. Backwards Compatibility

When it comes to compatibility, Java has a great record. Based on its backward compatibility, the Java community can stand on each other's shoulders and jointly create the glory of the Java language for twenty years - of course, another major factor is the longevity of the language.

10. Maturity and Innovation

As the saying goes, the waves behind the Yangtze River push the waves ahead, and a new generation replaces the old. The same is true in the technical field. Many people will feel that Java is very old and no longer suitable as an entry-level language. However, the ever-lasting Java still not only has excellent reliability, but also is very stable. Teams can also easily use it to create products without stepping on anyone's shortcomings.

In short,

"Intelligent integrated development environment, backward-compatible platform, large-scale core API, vibrant open source community, and readable and encapsulated language make Java a perfect bridge for teamwork .”
