Cloning of objectsWhen copying a variable, the original variable references the same object as the copy variable, which means that changing the object referenced by one variable will have an effect on the other variable. Such as:// Copy New Employee ("Jim", 10000= orginal; // Cloning Employee copy = Original.clone ();The Clone () method is an proteced method of the object class, which means that it cannot b
VMware virtual machine After cloning operation, will find that the cloned host eth0 will be missing, instead there will be a new Mac network card eth1, restart the network card, found that error, no device found for connection ' System eth0′, The specific error code is as follows:
Shutting down loopback interface: [OK]
Bringing Up loopback interface: [OK]
Bringing up interface Eth0:Error:No suitable device found:no device found for connection
Background: Sometimes we use multiple uses when using virtual machines. The reinstallation takes a lot of time, and we can quickly clone the exact same system with the functionality that comes with the VMware virtual machine. Prerequisite: The cloned virtual machine system is in the off stateStep:VM ( virtual machine )-manage ( Management )-clone ( clone )There are 2 ways of Cloning:1. Link Clone2. Complete cloningIn order to save space and time, the

The script is hung in the preset, and after cloning the preset, it then changes the value of the script in the preset.
We later found that the value of the script in the preset is not the value we changed
The reason behind this is that there is a variable assignment in the start () function. The start function is executed after cloning and assigning a value to the variable.

Perhaps you would say, with clone () do not do it?! Your idea is only half right, because when you use Clone (), other complex types (such as collections, objects, and so on) will be affected in addition to the underlying data and string types! Unless you clone () the complex type in each object, t
