Java libraries can be either built-in or third-party. The built-in libraries are part of the Java Development Kit (JDK) and include core classes and packages such as java.lang, java.util, and java.io. Third-party libraries are developed by independent developers or organizations and can be downloaded and added to a Java project as dependencies.
