JavaScript overload functions are generally operated by arguments.For example:Copy codeThe Code is as follows:Var afunc = function (){Args = arguments;If (args. length = 1 ){Console. log (1 );} Else if (args. length = 2 ){Console. log (2 );} Else if

The Java heap is a runtime data zone, and the instance (object) of the class allocates space from it. The Java Virtual Machine (JVM) Heap stores all objects created by running applications. These objects are created through commands such as new,

in Java, when using array to sort the function, there are four kinds of methods: fast sorting method, bubbling method, choosing Sort method, inserting sort method. The fast sorting method mainly uses a method arrays.sort () implementation in

One, subprocess and commonly used encapsulation functionsWhen we run Python, we are all creating and running a process. Like the Linux process, a process can fork a child process and let the child process exec another program. In Python, we fork a

Zookeeper as a C/S mode of application, the client is mainly processing (encapsulation) user requests, serialization, and then the socket to send to the server, the server to deserialize after the processing of client request data. Here is the

One, why to Subprocess Starting with Python 2.4, Python introduced the subprocess module to manage the subprocess to replace the methods of some old modules: Os.system, os.spawn*, os.popen*, popen2.*, commands.*, Not only can the external command be
