original 1. 介绍类加载器 类加载器负责在运行时动态地加载Java类到Java虚拟机。当然,类加载器也是Java运行时环境的一部分。因此,Java虚拟机并不需要了解...
Class Loaders in the Java 2 Platform The Java programming language keeps evolving to make the life of applications developers easier everyday. This is done by providing APIs that simplify your life by allowing you to concentrate on business logic rather than implementation details of fundamental mech...
1. **Bootstrap Class Loader**：也称为引导类加载器，是JVM的内部加载器，负责加载Java的核心类库，如`java.lang`包中的类。它是JVM中的一部分，由C++实现，并不是Java类。2. **Extension Class Loader**：扩展类加载器负责加载Java的扩展类库，位于`jre/lib/ext`目录下的JAR文件。可以通过系统属性`java.e...
Class Loaders是JRE(Java Runtime Environment)的一部分,当JVM需要一个类的时候,Class Loader就会通过类的全名尝试定位到类文件(.class文件,字节码)的位置,并通过类文件定义成一个Java类(java.lang.Class的一个实例);另外的,ClassLoader还负责加载应用需要的资源,如配置文件,图片等等。 核心API 下面主要了解一下load...

The Java run-time has the following built-in class loaders: Bootstrap class loader. It is the virtual machine's built-in class loader, typically represented as null, and does not have a parent. #getSystemClassLoader() System class loader. It is also known as application class loader ...

How Java ClassLoader Works? Let’s understand the working of class loaders from the above program output. Thejava.util.HashMapClassLoader is coming as null, which reflects Bootstrap ClassLoader. The DNSNameService class ClassLoader is ExtClassLoader. Since the class itself is in CLASSPATH, Sys...
