All outstanding programmers will do their best to make their programs more reusable, because it allows you to quickly write more robust and scalable programs.
There are two options for code reuse:
1. white box: the simplest one is to copy your program to another file.2. Black Box: it includes connecting compiled program slices. Therefore, the compiled black box class library that can be called by the client is called a component.

The object-oriented idea is difficult to adapt to this distributed software model, so the idea of componentized programming has developed rapidly. According to the idea of componentized programming, complex applications are designed into small, single-functional component modules that can run on the same machine, it can also run on different machines. In order to implement such an application, some extremely detailed specifications are required between the build program and the build program. On

Now, let's go to the other side and develop a COM client in Java. This program invokes the service within the COM server that the system has installed. For the present example, we are using a client that was implemented for the server in the previous example. Although the code looks familiar in the eyes of the Java programmer, everything that happens behind the scenes is unusual. This example uses a Java-wr
