Usage

From source file:DataIODemo.java

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

    // write the data out
    DataOutputStream out = new DataOutputStream(new FileOutputStream("invoice1.txt"));

    double[] prices = { 19.99, 9.99, 15.99, 3.99, 4.99 };
    int[] units = { 12, 8, 13, 29, 50 };
    String[] descs = { "Java T-shirt", "Java Mug", "Duke Juggling Dolls", "Java Pin", "Java Key Chain" };

    for (int i = 0; i < prices.length; i++) {
        out.writeDouble(prices[i]);//from   w  w w  .  j  av  a  2 s  .  co  m
