Closes this output stream and releases any system resources associated with the stream.

Usage

From source file:Main.java

public static void main(String[] args) throws Exception {

    // create input streams
    OutputStream os = new FileOutputStream("C://test.txt");
    FilterOutputStream fos = new FilterOutputStream(os);

    // releases any system resources associated with the stream
    fos.close();

    // writes byte to the output stream
    fos.write(65);//w  ww.  j av  a  2s  .  c  o  m

}
