// of PipedInputStream
import java.io.*;
public class CloseOfPIS {
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();
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++;
}
// By using close() method is to close
// the stream
pipe_in.close();
pipe_out.close();
// when we call read() after closing the stream
// will result an exception
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_in.read();
System.out.println("pipe_in.read(): " + ch);
