JDK is the abbreviation of Java Development Kit, which is a software development kit, mainly used for java applications on mobile devices and embedded devices. JDK is the core of the entire Java development. It includes the JAVA running environment (JVM Java system class library) and JAVA tools.
It is a development environment for building applications, applets, and components published on the Java platform. It includes the Java compiler, JVM, a large number of Java tools and the Java basic API, which contains the Java class library and Java language specifications. At the same time, any improvements to the Java language should be added to it and released as subsequent versions. To become a programmer, JDK is the most basic tool.
Java SDK was first called Java Software Develop Kit, and later changed its name to JDK, which is Java Develop Kit. JDK, as a Java development toolkit, is mainly used to build applications, applets, and components that run on the Java platform.
The functions of JDK are as follows:
Its function is a development environment for building applications, applets and components published on the Java platform. It does not provide specific development software. What it provides is the class library and Java language specification that must be used no matter what kind of development software you use to write Java programs.

To set up the JVM, you need to follow the following steps: 1) Download and install the JDK, 2) Set environment variables, 3) Verify the installation, 4) Set the IDE, 5) Test the runner program. Setting up a JVM is not just about making it work, it also involves optimizing memory allocation, garbage collection, performance tuning, and error handling to ensure optimal operation.

The core features of Java include platform independence, object-oriented design and a rich standard library. 1) Object-oriented design makes the code more flexible and maintainable through polymorphic features. 2) The garbage collection mechanism liberates the memory management burden of developers, but it needs to be optimized to avoid performance problems. 3) The standard library provides powerful tools from collections to networks, but data structures should be selected carefully to keep the code concise.
