Java Abstract Class Example

Base Class :
=============

package pkg_abstract;

import java.awt.Frame;
public class BaseWindow extends Frame {
}
Derived Class :
=============

package pkg_abstract;

public class EDSWindow extends BaseWindow{
public static void main(String args[])
{
EDSWindow a = new EDSWindow();

}
}

Filter Pattern

package com.filter;

import java.util.Iterator;
import java.util.Vector;

public class FilterChain {
// filter chain
private Vector myFilters = new Vector();

// Creates new FilterChain
public FilterChain() {
// plug-in default filter services for example
// only. This would typically be done in the
// FilterManager, but is done here for example
// purposes
addFilter(new DebugFilter());
addFilter(new LoginFilter());
addFilter(new AuditFilter());
}

javax.servlet.http.HttpServletRequest request,
javax.servlet.http.HttpServletResponse response)
throws javax.servlet.ServletException,

// apply filters

// pass request & response through various
