PipedInputStream类的receive()方法 (PipedInputStream Class receive() method)

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

  receive()方法在java.io包中可用。

• receive() method is used to receive a byte of content and it will block when no more input remains.

  receive()方法用于接收内容的一个字节，当不再有剩余输入时它将阻塞。

• receive() 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.

  receive()方法是一个非静态方法，只能通过类对象访问，如果尝试使用类名称访问该方法，则会收到错误消息。

• receive() method may throw an exception at the time of receiving a byte of data.

  receive()方法在接收到一个字节数据时可能会引发异常。

  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。

Example:

例：

// Java program to demonstrate the example // of receive(int byt) method of PipedInputStreamimport java.io.*;public class ReceiveOfPIS extends PipedInputStream {
       public static void main(String[] args) throws Exception {
           int val = 65;                try {
               // Instantiates ReceiveOfPIS and             // PipedOutputStream            ReceiveOfPIS pipe_in = new ReceiveOfPIS();            PipedOutputStream pipe_out = new PipedOutputStream();            // By using connect() method is to            // connect this pipe_in to the given pipe_out            pipe_in.connect(pipe_out);            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 receive() method is to                // receive a byte                pipe_in.receive(val);                System.out.println(i + " " + "Byte Received ");            }            // By using close() method is to close            // the stream            pipe_in.close();            pipe_out.close();        } catch (Exception ex) {
               System.out.println(ex.toString());        }    }}
