Let's put this program to work now We start as we did in the last example, employees, by creating the applet we'll need, the window we'll use, and installing the applet in the window In addition, we add the controls we'll need[md]the forward and back buttons and the Add record and Save database buttons[md]in the + method: import commsxmlParseException;
import commsxmlDocument;
import commsxmlElement;
import javaio*;
import javaawt*;
import javanet*;
import javaappletApplet;
public class birds extends Applet{
static String filename;
Label birdLabel, dateLabel;
TextField text1, text2;
Button button1, button2, button3, button4;
Document d;
int currentRecordNumber = 0;
int maxRecordNumber = 4;
public static void main(String args[])
birdsFrame frame = new birdsFrame("The birds application");
frameshow();
framehide();
frameresize(330, 320);
birds applet = new birds();
frameadd("Center", applet);
appletinit();
appletstart();
frameshow();
public void init()
birdLabel = new Label("Bird:");
add(birdLabel);
text1 = new TextField(30);
add(text1);
dateLabel = new Label("Date:");
add(dateLabel);
text2 = new TextField(30);
add(text2);
button1 = new Button("<");
add(button1);
button2 = new Button("Add record");
add(button2);
button3 = new Button("Save database");
add(button3);
button4 = new Button(">");
add(button4);
URL url = null;
try {
url = new URL("file:////c://xml//birds//birdsxml");
catch (MalformedURLException e1) {
Systemoutprintln("Cannot create url for: " + filename);
Systemexit(0);
d = new Document();
try {
dload(url);
catch (ParseException e3) {
dreportError(e3, Systemout);
if (d != null) {
maxRecordNumber = dgetRoot()numElements() - 1;
showRecord(0);
At the end of the + method That method is the same as in the employees example, except that we search for <BIRD> and <DATE> tags, not <LASTNAME> and <FIRSTNAME>: void showRecord(int recordNumber)
Element root = dgetRoot();
Element elem = null, elem2 = null;
Enumeration enum = rootgetChildren();
for(int index = 0; index <= recordNumber; index++){
elem = (Element)enumnextElement();
Enumeration enum2 = elemgetChildren();
for(int index = 0; index < 2; index++){
elem2 = (Element)enum2nextElement();
if (elem2getTagName()equals("BIRD")) {
text1setText(elem2getText());
if (elem2getTagName()equals("DATE")) {
text2setText(elem2getText());
Now we'll handle the four buttons in the application in the + method We start with the back button, which moves us back a record in the birds database Here, we simply decrement the current record number and (if we haven't tried to move back before the database's first record), display the new record: public boolean action (Event e, Object o){
if(etargetequals(button1)){
//The < button
if(currentRecordNumber > 0){
currentRecordNumber--;
showRecord(currentRecordNumber);
On the other hand, if the user pressed the Add record button (button2), we should take the text strings in the text fields text1 and text2 and create a new record in the database like this: <SIGHTING>
<BIRD>
Falcon
</BIRD>
<DATE>
June 7
</DATE>
</SIGHTING>
Creating a New XML Element
We start the element-creation process like this, where we use the + method to create a new <SIGHTINGS> element that the program will add to the end of the database: public boolean action (Event e, Object o){
if(etargetequals(button1)){
//The < button
if(etargetequals(button2)){
//The Add record button
Element elem = dcreateElement(new String("SIGHTING"),
ElementELEMENT);
Now we create the <BIRD> element, which has one child, the character data from the text field text1: <SIGHTING>
<BIRD>
Falcon
</BIRD>
<DATE>
June 7
</DATE>
</SIGHTING>
Here's how we create the <BIRD> element, give it a + element to the <BIRD> element: public boolean action (Event e, Object o){
if(etargetequals(button1)){
//The < button
if(etargetequals(button2)){
//The Add record button
Element elem = dcreateElement(new String("SIGHTING"),
ElementELEMENT);
Element t1 = dcreateElement(new String("BIRD"), ElementELEMENT);
Element x1 = dcreateElement(null, ElementPCDATA);
x1setText(text1getText());
t1addChild(x1, null);
You pass two arguments to + as the second argument adds the element to the beginning of the list
Tip: If you want to remove a child element from a document instead of adding one, use the removeChild() method
Next, we create the <DATE> element using the date in the second text field, text2: <SIGHTING>
<BIRD>
Falcon
</BIRD>
<DATE>
June 7
</DATE>
</SIGHTING>
Here's how we create a new <DATE> element, just as we created the <BIRD> element: public boolean action (Event e, Object o){
if(etargetequals(button1)){
//The < button
if(etargetequals(button2)){
//The Add record button
Element elem = dcreateElement(new String("SIGHTING"),
ElementELEMENT);
Element t1 = dcreateElement(new String("BIRD"), ElementELEMENT);
Element x1 = dcreateElement(null, ElementPCDATA);
x1setText(text1getText());
t1addChild(x1, null);
Element t2 = dcreateElement(new String("DATE"), ElementELEMENT);
Element x2 = dcreateElement(null, ElementPCDATA);
x2setText(text2getText());
t2addChild(x2, null);
Adding a New XML Element to a Document
All that remains is to add the <BIRD> and <DATE> elements to the new <SIGHTING> element, add the new <SIGHTING> element to the document itself (by adding it to the + element), and
increment the maximum number of records: public boolean action (Event e, Object o){
if(etargetequals(button1)){
