Java development kit? Maybe? Not 100% sure. You can extract the .jar file with WinRAR and then use some java development software to edit it. Then you can put the file back in the "archive" the .jar file opnened with WinRAR.

there are some people who were able to edit jar files but i really don't know what did they use. some of the things that i wanna modify are:
first: the name of the application after installing the jar file
second: the network settings of an application so that i can use that specific application for free without being charged by our network provider
i know how to do that but i don't know what editor will i use.

everytime i extract a jar file, it shows me the class files and also the icon of the application to be installed. everytime i try to open a class file in notepad, it shows me special characters. i want to know how to access the source codes by decompling it.

The source codes are always special charecters,and each charecter has special meaning or value .
Its very different from normal java and c language .
One needs to have knowledge of java (j2me) programming in order to modify the source codes.

As you told earlier that you want to edit the network settings of the app. U can do that very easily of a signed app. by editing its jad file by using Mobyexplorer on your phone itself. And then installing the app from the edited jad file.

I think these informations can be found in the manifest file that every java app contains... I'm 100% sure for the name changes.. I have done it thousand times before. But for the other, try yourself. And you need only notepad to open and edit that file. Nothing special.
