How to run the. Class file...

Java file running method (in the console ):
Java package name + class file
If the Java class exists in the default package, it can be run directly with the class name. However, if the Java class exists in the Custom package, the package name should be added during running, for example, server. class is located in the src.bill.net package, server. the class file is located in the C: \ Java folder. When running, enter c: \ Java> JAVA src.bill.net in the console. server. class [arguments]
Although you can see the server in the file system. the class is in the C: \ Java \ SRC \ Bill \ net> folder, but it cannot be input as C: \ Java \ SRC \ Bill \ net> Java Server. class [arguments]
In this way, it cannot run because the Java class package information is not provided.
