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.
当此PipedOutputStream先前未连接到任何其他PipedInputStream时,使用connect()方法使此PipedOutputStream连接到给定的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()方法是一种非静态方法,仅可通过类对象访问,如果尝试使用类名访问该方法,则会收到错误消息。
connect() method may throw an exception at the time of connecting the stream.
connect()方法在连接流时可能会引发异常。
IOException: This exception may throw when getting any input/output error or pipe not connected properly, or stream closed.
IOException:当出现任何输入/输出错误或管道未正确连接或流关闭时,可能引发此异常。
Syntax:
句法:
public void connect(PipedInputStream pis);
Parameter(s):
参数:
PipedInputStream pis – represents the piped input stream to connect to this piped output stream.
PipedInputStream pis –表示连接到此管道输出流的管道输入流。
Return value:
返回值:
The return type of the method is void, it returns nothing.
该方法的返回类型为void ,不返回任何内容。
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 // PipedOutputStream PipedInputStream pipe_in = new PipedInputStream(); PipedOutputStream pipe_out = new PipedOutputStream(); // By using connect() method is to // connect this pipe_out to the given pipe_in pipe_out.connect(pipe_in); for (int i = 0; i < 3; ++i) { // By using write() method is to // write the val to the stream pipe_out pipe_out.write(val); val++; } for (int i = 1; i < 4; ++i) { // By using read() method is to read // the integer and converted into int char ch = (char) pipe_in.read(); System.out.println("pipe_in.read(): " + ch); } // By using close() method is to close // the stream pipe_in.close(); pipe_out.close(); } catch (Exception ex) { System.out.println(ex.toString()); } }}
