Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    FileOutputStream fileOut = new FileOutputStream("data.txt");
    BufferedOutputStream buffer = new BufferedOutputStream(fileOut);
    DataOutputStream dataOut = new DataOutputStream(buffer);
    dataOut.writeUTF("Hello!");
    dataOut.writeInt(4);/*from w w  w .ja  va  2  s .c o m*/
    dataOut.writeDouble(100.0);
    dataOut.close();
    buffer.close();
    fileOut.close();
}

From source file:Main.java
