The PipedWriter class in Java is employed to write characters to a pipe as a character stream. It is primarily used for writing text content. Typically, PipedWriter is linked to a PipedReader and can be utilized by multiple threads simultaneously.
Constructor
| Constructor | Description |
|---|---|
| PipedWriter() | It creates a piped writer that is not yet connected to a piped reader. |
| PipedWriter(PipedReader snk) | It creates a piped writer connected to the specified piped reader. |
Method
| Modifier and Type | Method | Method |
|---|---|---|
void |
close() | It closes this piped output stream and releases any system resources associated with this stream. |
void |
connect(PipedReader snk) | It connects this piped writer to a receiver. |
void |
flush() | It flushes this output stream and forces any buffered output characters to be written out. |
void |
write(char[] cbuf, int off, int len) | It writes len characters from the specified characterarraystarting at offset off to this piped output stream. |
void |
write(int c) | It writes the specified char to the piped output stream. |
Example
Example
import java.io.PipedReader;
import java.io.PipedWriter;
public class PipeReaderExample2 {
public static void main(String[] args) {
try {
final PipedReader read = new PipedReader();
final PipedWriter write = new PipedWriter(read);
Thread readerThread = new Thread(new Runnable() {
public void run() {
try {
int data = read.read();
while (data != -1) {
System.out.print((char) data);
data = read.read();
}
} catch (Exception ex) {
}
}
});
Thread writerThread = new Thread(new Runnable() {
public void run() {
try {
write.write("I love my country\n".toCharArray());
} catch (Exception ex) {
}
}
});
readerThread.start();
writerThread.start();
} catch (Exception ex) {
System.out.println(ex.getMessage());
}
}
}
Output:
Output
I love my country
