Java factory model learning, java factory Model
There are three factory models: simple factory, factory method, and abstract factory. The abstract factory is used for multiple product families. The product family is an organic whole composed of different products, and different products depend on each other. For example, a computer has a CPU, motherboard, memory, and hard disk. These products form a product family. For example, if Dell and HP want to assemble these products differently, they nee

The use of these two methods is given directly below: /** * FileChannel's Transferfrom () method can transfer da

The above example shows the idea of copying files. In fact, if it is FileChannel, you can also use the transferFrom () and transferTo () Methods to copy files. The following describes the usage of the two methods:
