Cause analysis: Many Linux uses udev to dynamically manage device files and to persist names based on device information, andVMware automatically generates Mac addresses for virtual machines. In this way, because the virtual machine of the base system has recorded the NIC mac address of the virtual

other classes used in methods do not affect the code of this program. Normal method return If the current method ends normally, a returned command with the correct type will be returned when the called method is executed. The execution environment is used to restore the caller's register when the caller returns normally, and adds an appropriate value to the caller's program counter to skip the executed method call command, then, the invocation continues in the caller's execution environment. E

machine creates an instance of the Java.lang.Class class for it to represent the type. The user-defined class loader and instances of the class class are placed in the in-memory heap area, while the type information loaded is located in the method area. In addition to locating and importing binary class files, class loaders also need to be responsible for the correctness of imported classes, assigning variables and initializing memory, parsing symbol

The new Linux virtual machine is configured with Vi/etc/sysconfig/network-scripts/ifcfg-eth0:Then use Ifconfig to see if the IP is not eth0, only lo and virbr0Where lo is a loopback device. This is a necessary device, so long as Linux is enabled for support of the network, it will have this device.And Virbr0 is a virtual network connection port.Run Ifconfig-a als

Java Virtual machine Model Because of its high portability, Java has become the primary programming language on the Internet. The concept of "simulator" is one of the most commonly used explanations of virtual machines in computer industry. This

the object header). This step ensures that the instance fields of an object can be used directly in Java code without assigning an initial value, and the program can access the 0 values corresponding to the data types of those fields.4. Make the necessary settings for the object, for example, the object is an instance of which class, how to find the metadata information of the class, the object's hash code

earlier, the. class file does not have to be compiled from the Java source code and can be generated in any way, even with a hexadecimal editor that is written directly to produce a. class file. At the bytecode language level, Java code can be expressed at least semantically. If the virtual machine does not check the
