(Good beginner java tutorial, very specific. It is suitable for beginners, and I have seen it myself. Bin is an executable file, exe or bat file. The most commonly used Javac (compile java code) and java (execute java code) are located in this directory. Later, when we configure the environment variables, we mainly configure its way, so that the operating system can find Javac (compile java code) and java (execute java code), and then run commands directly in the console. This is explained in detail later. Lib: is a class library that java uses to run the program. It needs to be used when compiling and executing. Jre: Like the above jre, it is a java runtime environment. Don't care. Include: This includes the implementation of the c program that the jvm needs to implement on the windows operating system. Don't care.
