Basically to begin an development for sure is an idea to start with. What application you going to develop / build. I wont mention the software development life cycle in here that was too bored start with those theory. For sure you need a tools to start a software development which is... tata.... a pc... lolx..
For the software tools that use to develop a application know as software development kit (SDK) or IDE. (Google it to know more about the different)
So for Java application development, I am begin by using BlueJ then follow by Netbeans. Both of this tools is very easy to setup like ABC. To setup of these tool you must have to install the java JDK before install this software. What i like this tool is it is FREE, this is one of the good thing about Java.
For the ASP development tool is MS Visual Studio. The language use might be C#, VB.... You may develop webpage, console application, desktop apps, and mobile app by using only this application. But this is license software. Installer size is huge and take time to install.
Lastly the most frequent use program to open those source code is Notepad++. I like this program very much as it able to open many file type of code file and formatted accordingly and colored to identify the reserve words.
