== Demo code for Template pattern ==



<source lang="java">
abstract class ApplicationFramework {
public ApplicationFramework() {
templateMethod(); // Dangerous!
}
abstract void customize1();
abstract void customize2();
final void templateMethod() {
for (int i = 0; i < 5; i++) {
customize1();
customize2();
}
}
}
class MyApp extends ApplicationFramework {
void customize1() {
System.out.print("Hello ");
}
void customize2() {
System.out.println("World!");
}
}
public class TemplateMethod {
public static void main(String args[]) {
MyApp app = new MyApp();
}
}</source>



== Template pattern with abstract class ==



<source lang="java">
public class TestTemplate {
public static void main(String args[]) {
