Example:

例：

// Java program to demonstrate the example 
// of void connect(PipedWriter source) method of 
// PipedReader
import java.io.*;
public class ConnectOfPR {
public static void main(String[] args) throws Exception {
int val = 65;
try {
// Instantiates PipedReader and PipedWriter
PipedWriter pipe_w = new PipedWriter();
PipedReader pipe_r = new PipedReader();
// By using connect() method is to connect
// this pipe_r to the given pipe_w
pipe_r.connect(pipe_w);
for (int i = 0; i < 3; ++i) {
// By using write() method is to
// write the val to the stream pipe_w
pipe_w.write(val);
val++;
}
for (int i = 0; i < 3; ++i) {
// By using read() method is to
// read the integer and convert it into
// char
char ch = (char) pipe_r.read();
System.out.println("pipe_r.read(): " + ch);
}
// By using close() method is to close
// the stream
pipe_w.close();
pipe_w.close();
} catch (Exception ex) {
System.out.println(ex.toString());
}
}
