Java SE Error in cmd
<p>I downloaded Java SE Development Kit 7u7 and then I tried to make a simple program in Notepad to see if it works.I wrote the program , saved it in notepad.</p>

<p>(Note: As I was saving I noticed that in the Save as type the java extension wasn't there, so I just added .java at the end of the name of my program) </p>

<p>For this java I tried using cmd but as far as I have understood, it doesn't find it. As error it says the first world of my first file i try to use "is not recognized as an internal or external command, operable program or batch file". Could there be a problem with my PC , the java or does this have to do with the fact that I used Notepad instead of Notepad++ wich I have heard is better than the simpler one?</p>
