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 {

    char b = 'F';

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

    // write something in the file
    oout.writeChar(b);//from   www . j  av  a 2s .  co  m
    oout.writeChar('A');
    oout.flush();
    oout.close();
    // create an ObjectInputStream for the file we created before
    ObjectInputStream ois = new ObjectInputStream(new FileInputStream("test.txt"));

    // read and print a char
    System.out.println(ois.readChar());

    // read and print a char
    System.out.println(ois.readChar());
    ois.close();
}

From source file:MainClass.java

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

    record = new AccountRecordSerializable(1, "firstName", "lastName", 0.1);
    output.writeObject(record);

    output.close();
}
