<h1 class="pgc-h-arrow-right" What is the JDK > data-track="1"? </h1>

JDK is an abbreviation for Java Development Kit. It is a development environment for building applications, applets, and components that are released on the Java platform. These include the JVM, the Java compiler, a large number of Java tools, and the Java base API that houses the Java class library and java's language specification, and any improvements to the Java language should be added to it and released as a follow-up release. To become a programmer, the JDK is one of the most basic tools.

<h1 class="pgc-h-arrow-right" data-track="3" > JDK consists of three parts:</h1>

(1) JRE (i.e. Java development environment);

(2) Java tools (including compiler javac.exe and actuator java .exe)

(3) Java class library (there are more than 3000 classes, commonly used generally 150 classes)

JDK source code can be said to be the most basic tool, proficient in JDK source code, I believe that for other source code can also be handy. JDK source code is one of the most commonly used tools for programmers, and it can be seen that JDK source code has a pivotal role. Secondly, the JDK source code is called an offer harvester in the interview of the big factory, as long as you can see, it is a plus.

<h1 class="pgc-h-arrow-right" data-track="8" > the role of the JDK</h1>

JDK is a software development kit for the Java language, mainly used for Java applications on mobile devices and embedded devices. The JDK is the core of the entire Java development, it contains the JAVA runtime environment, JAVA tools and Java-based class libraries. THE JDK and JRE are Java development and runtime tools, where the JDK contains THE JRE, but the JRE can be installed independently

When it comes to the JDK source code, Xiaobian also made some preparations, and spent time deliberately collecting a copy of the JDK source code notes written by Ali gangsters for many years. Let's talk about it with everyone.

So, let's take a closer look at the JDK source code with Xiaobian!

The following will show you a screenshot of some of the content in the notes, and the small partner who needs to get it can directly forward + pay attention to the private message (learning) can be obtained for free!

Second, let's take a look at the content
