intuitiveThe following diagram shows the composition concept of JavaSE8:It can be seen clearly that JavaSE8 consists of 4 parts: JVM, JRE, JDK, and Java language. The second section will cover these 4 sections in detail.2. Detailed concept of compositionNow we pick up the scalpel to dissect the pieces. Below we explain the parts from the bottom up.2.1. JVM(Java

The above only contains the red part. C: \ Program Files \ Java \ jdk1.8.0 _ 101/bin is the java PATH variable. Note that the variables must be separated. 2. CLASSPATH environment variable. The function is to specify the Class search path and use the classes that have already been compiled. The premise is that you can find them, and JVM searches for classes thro

users, and user environment variables only work for the current user. Fill in the variable name and variable value. (1) Java_home is the path to the JDK in the Java installation path. (Ensure that software such as JCreator, Eclipse, and MyEclipse works) For example: C:\Program files\java\jdk1.8.0_05 (2) PATH The
