Java (iv)--io stream

(i) Java streaming input/output principle:

In Java programs, input/output operations for data are carried out in a "stream" way to obtain different kinds of data, which are entered or output by standard methods in the program.

(ii) java.io abstract stream Classification:

node flow and processing flow:

A node stream can read and write data (files, memory) from a specific data source (node)

The processing flow is a "connection" over an existing stream (either a node stream or a processing stream), which provides the program with more powerful read and write capabilities through the processing of the data.

Basic methods of Io Flow:

Node stream: Write or read out

Processing flow: Converting data types

(iii) Summary:

is a beginner, so summed up there is not comprehensive place. In learning this piece of time, we should have full imagination, imagine a variety of channels to input and output data. This piece of son will also learn, and so on, in the back to fill this piece of knowledge! Please also give us a lot of advice!
