Autocomplete application

[jailall]

Hi everyone, my name is Navin.
I want to implement an autocomplete application so that if a user is typing in a word processing app. eg. Notepad, then a drop-down list will pop up
based on the letters that the user starts typing. For example if the user starts typing 'a' a drop-down list will appear with some possible matches which the user can then select.
When the user selects one of the elements in the drop-down list then that word will replace what the user was typing in notepad as if the user typed it out.
What i want to know is if this is possible to do with JAVA and how.
Remember the functionality of this application has to be spread across an external application like Notepad.
Forget about the drop-down, i can handle that. What has me baffled is how do i read in input from a keyboard and change this input based on the user selection.

What you describe can't be done in Java.
