小结: 1.实现一台Java虚拟机,只需正确读取class文件中的每一条字节码指令且能正确执行这些指令所蕴含的操作. 2.设计者决定:运行时数据区的内存如何布局,选择哪种垃圾收集算法,是否对虚拟机字节码指令进行一些内部优化操作(如何用即时编译器把字节码编译为机器码) 3.请注意避免混淆Stack.Heap和Java(VM)Stack.Java Heap的概念.Java虚拟机的实现本质上是由其他语言所编写的应用程序,Java语言程序里分配在Java Stack中的数据,从实现虚拟机的程序角度上看则…

小结: 1. To facilitate communication between processes, most operating systems support Inter Process Communication (IPC) resources, such as pipes and sockets. IPC is used not just for communication between processes on the same system, but processes on…

Java Virtual Machine (JVM) is a specification that provides runtime environment in which java  bytecode can be executed. As the name implies, the JVM acts as a “virtual” machine or processor. Java's platform independence consists mostly of its Java V…

第一次运行Eclipse,经常会提示下面的问题:... No java virtual machine  was found after searching the follwing locations:d:javaeclipsejreinjavaw.exe'javaw.exe' in your current path. 意思:在指定路径"d:javaeclipsejreinjavaw.exe"没有找到javaw.exe.因为Eclipse启动时需要javaw.exe来启动.先查找p…

安装了Oracle之后,第一件事情就是想想怎么去连接,进而操作.SQL Developer是官方提供的强大工具,个人看来也是第一选择. 目前官网提供的最新版是4.0.1.14.48,下载下来之后,就跃跃欲试了.将下载下来的包解压,直接运行sqldeveloper.exe这个文件,选择了本地安装的JDK路径,之后却不幸的报错了,提示“unable to create an instance of the java virtual machine located at path”,具体界面如下: 解…
