Creates a file output stream to write to the specified file descriptor, which represents an existing connection to an actual file in the file system.

Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    FileOutputStream fos = new FileOutputStream("C:/demo.txt");
}

From source file:Main.java

public static void main(String[] args) throws Exception {
    FileOutputStream fos = new FileOutputStream("C:/demo.txt");

    byte b = 01;/*from   w  w w.j a va 2 s . c  om*/
    fos.write(b);
    fos.close();
}

From source file:Main.java

public static void main(String[] args) {

    try {/*  w  w  w  .  j  a  v  a  2s .  co  m*/
        OutputStream os = new FileOutputStream("test.txt");
        OutputStreamWriter writer = new OutputStreamWriter(os);

        // create a new FileInputStream to read what we write
        FileInputStream in = new FileInputStream("test.txt");

        // write something in the file
        writer.write(70);

        // flush the stream
        writer.flush();

        // read what we write
        System.out.println((char) in.read());

        // close the stream
        writer.close();
        os.close();
    } catch (Exception ex) {
        ex.printStackTrace();
    }
}
