Toolkit for Java pages

The so-called toolkit, refers to the function of the page is divided into another package inside. Aspects of project management, clear structure, teamwork and so on.

1. According to the original example: To do a com.myweb package of toolkit Com.myweb.tool
2. Creating interfaces uniformly for the navigation bar
3. Once created, to create some navigation bars on the page, divided into the top navigation bar and the bottom navigation bar
4. Create a factory and use the factory to generate the top navigation bar and the bottom navigation bar
5. Get the created elements and add them to the interface

It sounds a little more complicated, but I feel it's understandable.

The code is as follows;

 Package Com.myweb.tool;  Public Interface NavBar {    // navigation bar Interface public     String getbarcontent ();   get navigation bar }

Navigation Bar Interface

 Package Com.myweb.tool;  Public class Implements NavBar {    @Override    public  String getbarcontent () {        return "<a Href= ' > Home </a> | <a href= ' > news </a> | <a href= ' > User registration </a> ';    }}

Top navigation bar

 Package Com.myweb.tool;  Public class Implements navbar{    @Override    public  String getbarcontent () {        return "<a Href= ' > Home </a> | <a href= ' > About Us </a> | <a href= "> Job information </a>";    }    }

Bottom navigation bar

 PackageCom.myweb.tool; Public classBarfactory { Public StaticNavBar Createbar (String type) {NavBar NV; Switch(type) { Case"Top": NV=NewTopbar ();  Break;  Case"Bottom": NV=NewBottombar ();  Break; default: NV=NewTopbar ();  Break; }                returnNV; }}

Navigation Bar Factory

@Override PublicModelandview HandleRequest (httpservletrequest arg0, HttpServletResponse arg1)throwsException {modelandview mv=NewModelandview (view); /*Topbar Topnav = new Topbar ();                Mv.addobject ("Top_nav", Topnav.getbarcontent ());        Bottombar Bottomnav = new Bottombar (); Mv.addobject ("Bottom_nav", Bottomnav.getbarcontent ());*/NavBar Topnav= Barfactory.createbar ("Top"); NavBar Bottomnav= Barfactory.createbar ("Bottom"); Mv.addobject ("Top_nav", Topnav.getbarcontent ()); Mv.addobject ("Bottom_nav", Bottomnav.getbarcontent ()); returnMV; }
