答:本地方法栈是JVM用于执行本地(非Java)方法的内存区域。它与Java栈类似,但用于支持JNI(Java Native Interface)和其他本地接口技术。40.什么是JVM的程序计数器(Program Counter Register)?答:程序计数器是JVM中每个线程的一小部分内存区域,它用于跟踪当前线程执行的字节码指令的地址。当线程执行本地方法时...
NoClassDefFoundError is an error that is thrown when the Java Runtime System tries to load the definition of a class, and that class definition is no longer available. The required class definition was present at compile time, but it was missing at runtime. For example, compile the program b...

程序计数器(Program Counter Register)是一块较小的内存空间,它可以看作是**当前线程所执行的字节码的行号指示器。**在Java虚拟机的概念模型里,字节码解释器工作时就是通过改变这个计数器的值来选取下一条需要执行的字节码指令,它是程序控制流的指示器,分支、循环、跳转、异常处理、线程恢复等基础功能都需要依赖这个...
