The Java ClassLoader is a fundamental component of the Java Runtime Environment (JRE) that dynamically loads Java classes into the Java Virtual Machine (JVM). It plays a crucial role in the Java platform's ability to execute applications written in the Java programming language. The ClassLoader is responsible for reading class files, converting them into bytecode, and defining the classes in the JVM.
There are three main types of ClassLoaders in the Java platform:
1. Bootstrap ClassLoader: This is the first ClassLoader that loads the core Java libraries from the JAVA_HOME/jre/lib
2. Extension ClassLoader: This ClassLoader loads classes from the JAVA_HOME/jre/lib/ext directory. It is a child of
3. Application ClassLoader (or System ClassLoader): This ClassLoader loads classes from the application's classpath. It is
The ClassLoader uses a delegation model to load classes. When a class is requested, the ClassLoader first
The ClassLoader also supports the concept of class loading isolation, which allows multiple versions of the
In summary, the Java ClassLoader is a critical component of the Java platform that enables dynamic class
