Example:

例：

// Java program to demonstrate the example
// of receive(int byt) method of PipedInputStream
import 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());
}
}
}
