Java Class Library

The Java Class Library (JCL) is a set of dynamically loadable libraries that Java Virtual Machine (JVM) languages can call at run time. It is the standard library of Java and other JVM languages, and is thus sometimes called the Java Standard Library. Because the Java Platform is not dependent on a specific operating system, applications cannot rely on any of the platform-native libraries. Instead, the Java Platform provides a comprehensive set of standard class libraries, containing the functions common to modern operating systems. Since Java 9, the Java Class Library can be accessed through module path using the Java Platform Module System. JCL serves three purposes within the JVM: * Like other standard code libraries, they provide the programmer a well-known set of useful facilities, such as container classes and regular expression processing. * The library provides an abstract interface to tasks that would normally depend heavily on the hardware and operating system, such as network access and file access. * Some underlying platforms may not support all of the features a Java application expects. In these cases, the library implementation can either emulate those features or provide a consistent way to check for the presence of a specific feature. It uses the namespaces java.* , javax.* , and jdk.* .…
