The Java run time system does not need to know about files and file systems as this is delegated to the class loader. A software library is a collection of related object code. In the Java language, libraries are typically packaged in JAR files. Libraries can contain objects of different types.
An executable Java program can be packaged in a JAR file, along with any libraries the program uses.
