PipedOutputStream類的connect()方法 (PipedOutputStream Class connect() method)

• connect() method is available in java.io package.

  connect()方法在java.io包中可用。

• connect() method is used to cause this PipedOutputStream to be connected to the given PipedInputStream when this PipedOutputStream is not previously connected to any of the other PipedInputStream.

  當(dāng)此PipedOutputStream先前未連接到任何其他PipedInputStream時(shí)，使用connect()方法使此PipedOutputStream連接到給定的PipedInputStream。

• connect() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.

  connect()方法是一種非靜態(tài)方法，僅可通過類對(duì)象訪問，如果嘗試使用類名訪問該方法，則會(huì)收到錯(cuò)誤消息。

• connect() method may throw an exception at the time of connecting the stream.

  connect()方法在連接流時(shí)可能會(huì)引發(fā)異常。

  IOException: This exception may throw when getting any input/output error or pipe not connected properly, or stream closed.

  IOException：當(dāng)出現(xiàn)任何輸入/輸出錯(cuò)誤或管道未正確連接或流關(guān)閉時(shí)，可能引發(fā)此異常。

Syntax:

句法：

public void connect(PipedInputStream pis);

Parameter(s):

參數(shù)：

• PipedInputStream pis – represents the piped input stream to connect to this piped output stream.

  PipedInputStream pis –表示連接到此管道輸出流的管道輸入流。

Return value:

返回值：

The return type of the method is void, it returns nothing.

該方法的返回類型為void ，不返回任何內(nèi)容。

Example:

例：

// Java program to demonstrate the example // of void connect(PipedInputStream pis) method of // PipedOutputStreamimport java.io.*;public class ConnectOfPOS {public static void main(String[] args) throws Exception {int val = 65;try {// Instantiates PipedInputStream and // PipedOutputStreamPipedInputStream pipe_in = new PipedInputStream();PipedOutputStream pipe_out = new PipedOutputStream();// By using connect() method is to// connect this pipe_out to the given pipe_inpipe_out.connect(pipe_in);for (int i = 0; i < 3; ++i) {// By using write() method is to// write the val to the stream pipe_outpipe_out.write(val);val++;}for (int i = 1; i < 4; ++i) {// By using read() method is to read// the integer and converted into intchar ch = (char) pipe_in.read();System.out.println("pipe_in.read(): " + ch);}// By using close() method is to close// the streampipe_in.close();pipe_out.close();} catch (Exception ex) {System.out.println(ex.toString());}} }

Output

輸出量

pipe_in.read(): A pipe_in.read(): B pipe_in.read(): C
