Guide to ClassLoader in Java. Here we discuss the working, implementation, types, and principles of ClassLoader in Java along with its code implementation.
JCL is a light weight API and has only a few but useful classes. Here is a simple example on how to programmatically use JCL. JarClassLoader has an arguments-constructor and add methods that take jar-file/class-folder paths, URLs and InputStreams.
It can also be integrated with web applications and IoC frameworks like Spring, and supports OSGi boot delegation. Some libraries are in different versions in the classpath. The order is not defined so the behavior might change depending on OS, Java version and Java vendor. JarClassLoader: Warning: module-info.class in lib/jaxb-runtime-2.3.1.jar is h Dynamic linker API for the Java platform (JEP 276) in JDK 9 Early Access defines dynamic linker API for the Java platform.
Here is a simple example on how to programmatically use JCL. JarClassLoader has an arguments-constructor and add methods that take jar-file/class-folder paths, URLs and InputStreams. public final class JarClassLoader extends ClassLoader A class loader implementation that loads classes from JAR files. Each JAR file requires a separate instance of this class. Use the getInstance (String) method to get an existing or create a new instance for a specific JAR file. public class JARClassLoader extends java.lang.ClassLoader A class loader implementation that loads classes from JAR files. All instances share the same set of classes. JCL is a light weight API and has only a few but useful classes.
Java ClassLoader is an abstract class. It belongs to a java.lang package. It loads classes from different resources.
