Help need on System setup for java programming

Question

HELP BADLY NEEDED!
I recently installed java (jdk version8 152mb) on my HP630 win7 because i want to learn java. But when practising, after using notepad to code samples like "Hello Word" and saving it with .java format, it still cannot run on my pc.
Pls i think i need a complete and comprehensible guide on how to install and prepare my win7 laptop for java programming.
Thanks in anticipation

Hello,
   one suggestion is to ensure your system's environment PATH has the Java installation path included, so that it knows where to look to run Java.
 (See attached pix).
1st) Find out where Java was installed to on your system: For example, on my Win7 PC, Java was installed to 'C:\Program Files (x86)\Java' directory.
      However, my path to the actual binaries is 'C:\Program Files (x86)\Java\jre7\bin'; this is the value I added to my system PATH.
2nd) Check what your System's PATH has: You can do this by looking at the Environment Variables under System Properties:
   1) Search for Control Panel, then go to System & Security, then to System, then to 'Advanced System settings'.
   2) Click on 'Environment Variables...'
   3) Under the 'System variables' pane, use the scroll bar to find 'Path', and click on 'Edit...'.
   4) Here is where you add your Java path (as noted above): Note that I appended my java path to the existing Path text, taking care to separate the previous path with a semi-colon (';').
     For example, this was my existing 'Path': "C:\Program Files\CollabNet\"...and now it looks like this 'C:\Program Files\CollabNet\;C:\Program Files (x86)\Java\jre7\bin'.
   5) Click OK, OK, OK out of all those dialogs.
   Now..restart your JVM or attempt to run your Java program!.
 Good luck.
