Java English abbreviation detailed

1.jvm:java the abbreviation for Virtual machine (Java vm).

It is a fictitious computer, it is realized by simulating various computer functions on the actual computer.

a very important feature of the Java language is its independence from the platform. The use of Java virtual machines is the key to achieving this feature. General high-level languages if you want to run on a different platform, you need to compile at least a different target code . When the Java language virtual machine is introduced, the Java language does not need to be recompiled when it runs on different platforms. The Java language uses a Java Virtual machine to mask information related to a specific platform, allowing the Java language compiler to generate only the target code ( bytecode ) that runs on a Java virtual machine, which can be run unmodified on multiple platforms. When a Java virtual machine executes a bytecode, it interprets the bytecode as a machine instruction execution on a specific platform. This is why Java can be "compiled once and run Everywhere". 2.jre:java Runtime Environment
Jdk:java Development Kit

The JRE, as its name implies, is the Java Runtime Environment, which contains the Java virtual machine, the Java base Class library. The software environment that is required to run a program written in the Java language is provided to the user who wants to run the Java program.

The JDK, as its name implies, is the Java SDK, the developer kit needed by programmers to write Java programs in the Java language, and is available to programmers. The JDK contains the JRE, as well as compiler Javac, which compiles Java source code, and includes many tools for debugging and analyzing Java programs: JCONSOLE,JVISUALVM and other tools, as well as the documentation and demo example programs that Java programs need to write.

If you need to run a Java program, just install the JRE. If you need to write a Java program, you need to install the JDK.
The JRE has many versions based on different operating systems (such as windows,linux, etc.) and different JRE providers (ibm,oracle, etc.), most commonly the acquisition of the JRE version of Sun by Oracle Corporation.
