PipedInputStream available() in Java

available(): This method is available in the java.io.PipedInputStream class of Java.

Syntax:

int java.io.PipedInputStream.available() throws IOException

This method returns the number of bytes that can be read from this input stream without blocking.

Parameters: NA

Returns: the number of bytes that can be read from this input stream without blocking, or 0 if this input stream has been closed by invoking its close() method, or if the pipe is unconnected, or broken.

Throws:

IOException - if an I/O error occurs.

Approach

Java

import java.io.IOException;
import java.io.PipedInputStream;

public class PipedInputStreamavailable {
    public static void main(String[] args) throws IOException {

        PipedInputStream pipedInputStream = 
                               new PipedInputStream();

        System.out.println(pipedInputStream.available());

        pipedInputStream.close();
    }
}

Output:

0

Some other methods of PipedInputStream

close(): This method closes this piped input stream and releases any system resources associated with the stream.

connect(PipedOutputStream): This method causes this piped input stream to be connected to the piped output stream src.

available(): This method returns the number of bytes that can be read from this input stream without blocking.

PipedInputStream(): This method creates a PipedInputStream so that it is not yet connected.

PipedInputStream(int): This method creates a PipedInputStream so that it is not yet connected and uses the specified pipe size for the pipe's buffer.

PipedInputStream(PipedOutputStream): This method creates a PipedInputStream so that it is connected to the piped output stream src.

PipedInputStream(PipedOutputStream, int): This method creates a PipedInputStream so that it is connected to the piped output stream src and uses the specified pipe size for the pipe's buffer.

read(): This method reads the next byte of data from this piped input stream.

read(byte[], int, int): This method reads up to len bytes of data from this piped input stream into an array of bytes.
