Java

import java.io.ByteArrayInputStream;
import java.io.IOException;

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

        byte buf[] = { 1, 2, 3, 4 };
        ByteArrayInputStream byteArrayInputStream = 
                          new ByteArrayInputStream(buf);

        System.out.println(byteArrayInputStream.read());
        byteArrayInputStream.close();
    }

}
