java-节点流

1、三种基本类型的节点:

文件、内存和管道(从一个进程或线程式到另外一个进程或线程的通道)

2、

类型                              字符流                              字节流

文件                         FileReader                            FileInputStream

                             FileWriter                            FileOutputStream

内存：数组                   CharArrayReader                       ByteArrayInputStream

                             CharArrayWriter                       ByteArrayOutputStream

内存：字符串                 StringReader                          N/A

                              StringWriter                             

管道                         PipedReader                   PipedInutStream                   

                            PipedWriter                  PipedOutputStream       

3、这些流处理起来容易出错，提供了一些处理流的一种流，这种流专门处理流，可以一次一行地读取一个流，比如BufferedReader读，BufferedWriter写

1)

FileReader input=new FileReader(args[0]);

BufferedReader bufinput=new BufferedReader(input);

String line;

line=bufinput.readLine();

2)

FileWriter output=new FileWriter(args[1]);

BufferedWriter bufoutput=new BufferedWriter(output);

String line;

line=bufouput.newLine();

bufoutput.write(line,0,line.length);
