Document

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 {
    short b = 32767;

    FileOutputStream out = new FileOutputStream("test.txt");
    ObjectOutputStream oout = new ObjectOutputStream(out);

    // write something in the file
    oout.writeShort(b);//  www .  ja  v  a  2s. co m
    oout.flush();
    oout.close();
    // create an ObjectInputStream for the file we created before
    ObjectInputStream ois = new ObjectInputStream(new FileInputStream("test.txt"));

    // read and print the short
    System.out.println(ois.readUnsignedShort());
    ois.close();
}

From source file:FileDeflater.java

public static void main(String[] args) throws Exception {
    FileInputStream fin = new FileInputStream("a.dat");
    FileOutputStream fout = new FileOutputStream("b.dat");
    DeflaterOutputStream dos = new DeflaterOutputStream(fout);
    for (int c = fin.read(); c != -1; c = fin.read()) {
        dos.write(c);// ww  w .j  a v  a  2  s  .com
