Observer Design Pattern from https://www.newthinktank.com/2012/08/observer-design-pattern-tutorial/

I used a very basic Windows .bat file to build the code:

@echo off echo Compiling Java files...

javac -cp *.java

if errorlevel 1 goto buildFailed

echo Running application...

java -cp . GrabStocks

goto end

:buildFailed echo Build failed!

:end
