3、AppClass Loader(系统类加载器AppClassLoader):加载System.getProperty("java.class.path")所指定的路径或jar。在使用Java运行程序时,也可以加上-cp来覆盖原有的Classpath设置,例如: java -cp ./lavasoft/classes HelloWorld ExtClassLoader和AppClassLoader在JVM启动后,会在JVM中保存一份,并且在程序运行中无法改...

加载过程的基本步骤:JVM会动态的加载,链接,初始化class和interface,主要分为类文件的加载,链接,初始化。在链接阶段可以细分为验证,准备和解析。 加载:加载就是寻找类/接口的二进制标识,并且根据二进制表示创建类/接口 Loadingis the process of finding the binary representation of aclassorinterfacetypewithaparticula...
then the JAR files can be enumerated explicitly in the class path. Expansion of wild cards is done early, before the invocation of a program’s main method, rather than late, during the class-loading process. Each element of the input class path that contains a wildcard is replaced by the...

capable. In environments in which the delegation model is not strictly hierarchical, class loaders need to be parallel capable, otherwise class loading can lead to deadlocks because the loader lock is held for the duration of the class loading process (see#loadClass loadClassmethods). Normally...
