I am trying to convert my java program, TextFileAnalyzer, to a standalone application. I am not sure how to go about this I have done research and did not find anything helpful. If someone could get me in the right direction that would be awesome! Thanks.. Here is my program for reference:
You don't say what platform(s) you are targeting, or if you need to ship a complete executable. But, there are a few cross-platform Java wrappers. A common one is Launch4J.

I'd like to use shapefile (.shp) data in Java.
A sample file I have looks like this:
0105000000010000000102000000070000003085EF7995215FC0E0A2FEADF6E648400439100E8D215FC0B04AF9E80BE7484048CC79E78C215FC0F885E4F20CE74840B86EEC078C215FC0E80213FC12E74840A4B69A9694215FC07011B67744E7484008E900F396215FC04867DE1949E7484004D90A7EA1215FC0A8F7E1AE4BE74840
How can I can extract/decode all points (lat/lon) in this shapefile in java?
Pretty bad question my friend. Try to provide SSCCE.
If that binary you posted is really an .shp (file with the associated "helper" files such as .shx, .prj, etc), you can use a library such as GeoTools to read the file.
Attempting to read the file "by hand" with RandomAccessFile is unnecessary unless you really want to reinvent the wheel.

I want to compare 2 fingerprint images in Java. Can someone suggest an idea to do this? I know this question is a bit vague. But please suggest some tutorial / idea. Thanks in advance.
There are some algorithms for recognition...
Check this google code implementation: FingerPrint.java
There is also a .Net implementation here: http://sourceforge.net/projects/sourceafis/
Hope it helps.

I would like to know the steps in making a java speech recognizer/API WITHOUT using sphinx or anything else. I want to build from the ground up!!! Also a Text to speech from the ground up. 100% my own. I know it's going to be a lot of work. I just want to know.
First you want your sound-input as bytestream, how to do so is explained by oracle:
http://docs.oracle.com/javase/tutorial/sound/capturing.htmlNext, you write the logic and algorithms to analyze and process the byte stream.

Good luck.
