The classpath tells Java where to look in the filesystem for files defining these classes. The virtual machine searches for and loads classes in this order: bootstrap classes: the classes that are fundamental to the Java Platform (comprising the public classes of the Java Class Library , and the private classes that are necessary for this ...
The Java Class Library (JCL) is a set of dynamically loadable libraries that Java Virtual Machine (JVM) languages can call at run time. Because the Java Platform is not dependent on a specific operating system , applications cannot rely on any of the platform-native libraries.
Common practice in most Lisp dialects is to use dashes to separate words in identifiers, as in with-open-file and make-hash-table. Dynamic variable names conventionally start and end with asterisks: *map-walls*. Constants names are marked by plus signs: +map-size+. [29] [30]
A JAR ("Java archive") file is a package file format typically used to aggregate many Java class files and associated metadata and resources (text, images, etc.) into one file for distribution. [4] JAR files are archive files that include a Java-specific manifest file. They are built on the ZIP format and typically have a .jar file extension. [5]
A service is any class which contains useful functionality. In turn, a client is any class which uses services. The services that a client requires are the client's dependencies. Any object can be a service or a client; the names relate only to the role the objects play in an injection.
The cached files can be deleted without loss of data. /var/lib: State information. Persistent data modified by programs as they run (e.g., databases, packaging system metadata, etc.). /var/lock: Lock files. Files keeping track of resources currently in use. /var/log: Log files. Various logs. /var/mail: Mailbox files.

A Java class file is a file (with the .class filename extension) containing Java bytecode that can be executed on the Java Virtual Machine (JVM).A Java class file is usually produced by a Java compiler from Java programming language source files (.java files) containing Java classes (alternatively, other JVM languages can also be used to create class files).
