The Java Classloader, an integral component of the Java Runtime Environment (JRE), operates dynamically by loading Java classes into the Java Virtual Machine (JVM). Unlike programs written in C or C++, a Java program is not comprised of a solitary executable file, but rather consists of nume...
As of JDK 1.2, a bootstrap class loader that is built into the JVM is responsible for loading the classes of the Java runtime. This class loader only loads classes that are found in the boot classpath, and since these are trusted classes, the validation process is not performed as for ...
Every object had a reference to its class, which in turn had a reference to its classloader. However we didn’t mention that every classloader in turn has a reference to each of the classes it has loaded, each of which holds static fields defined in the class: 每一个object都有一个指向...

Let’s look at this hierarchy of class loaders in a Java application and explore what classes they typically load. At the root of the hierarchy, Java is the bootstrap class loader. It loads the system classes required to run the JVM itself. You can expect all the classes that were provid...
