Thread: An Overview of Java programming

Hello Everyone,
I'm new to programming, and I decided to go for Java.
After few days I'm able to write my first code (Land area conversion )which runs successfully in console.
So my BIG Question is that:
When you write a code for example in eclipse ide or intellij idea and you run that code in console successfully is that all you can do with that code?
What if I need that code to work like desktop application or web based app.
What if I need to make application such as hospital management app that run on desktop or browser.
or any Database app.
What tools of Java do I need to use to achieve that.
Pls help me with the procedure from writing code to making final application.
Thank you
