You need basics of (1) Web technologies (HTML5, CSS and Javascript) at the client side (2) Java technologies (Servlets, JSPs and JDBC for database connectivity) at the server side (3) An IDE (Netbeans / Eccliplse) will help you to develop web applcations faster !

Hi,

There are 3 types of Java applications for beginners.

1 : Command line applications

2: Desktop based applications

3: Web based applications

 

Other applications are also can be build in Java like, Phone applications (Android and IOS ), Microservices based application, Enterprise based EJB applications etc.

It depends upon your requirements which application you want to create, I will explain with example.

1. Web based Applications : The most importtant and common applications now a days are web based and you have many options to start with.

First choose your frame work to start with like Spring, Struts etc and backend Framework like Hibernate.

The Mostly used is Spring.

After this define your application entites and database design and choose backend Framework like Hibernate.

After you choose, Classify the application by creating small requirements and make a MVC (Model , View , Control ) diagrams .

And then start creating the Controllers and Backend DAO classes and choose front end technology like Json (to transfer data) or Node JS to work upon.

 

All the above, if the project is not very big, you can directly start working without any framework. Just start by creating UI with JSP and BAckend with servlets.
