Is java a programming language?

Java is an object-oriented programming language. As a representative of static object-oriented programming languages, Java language excellently implements object-oriented theory and allows programmers to elegantly way of thinking for complex programming.

Java programming environment                                                                                                                                                                                                                                     # The development kit or Java development tool is a program development environment for writing Java Applets and applications. JDK is the core of the entire Java, including the Java Runtime Environment (Java Runtime Envirnment), some Java tools and Java core class libraries (Java API). No matter what Java application server is, it essentially has a certain version of JDK built-in.

The mainstream JDK is the JDK released by Sun. In addition to Sun, there are many companies and organizations that have developed their own JDK, such as JDK developed by IBM, Jrocket by BEA, and GNU JDK developed by the organization.

In addition, the Java SE API subset and Java virtual machine in the Java API class library can be collectively referred to as JRE (JAVA Runtime Environment). JRE is a standard environment that supports the running of Java programs.

JRE is a running environment, and JDK is a development environment. Therefore, JDK is needed when writing Java programs, and JRE is needed when running Java programs. The JDK already contains JRE, so as long as the JDK is installed, you can edit Java programs and run Java programs normally.

However, since JDK contains a lot of content that has nothing to do with running and takes up a lot of space, you do not need to install JDK to run ordinary Java programs, but only need to install JRE.

Eclipse: an open source, Java-based extensible development platform. NetBeans: Open source Java integrated development environment, suitable for various client and Web applications.

IntelliJ IDEA: It has very good functions in automatic code prompts, code analysis, etc.

MyEclipse: A commercial software developed by Genuitec, it is a widely used integrated development environment for Java applications.

EditPlus: If the Java compiler "Javac" and the interpreter "Java" are correctly configured, you can directly use EditPlus to compile and execute Java programs.
