Yosemite/Java asks me to update to latest version of Java; which is already installed!

Question

Hello,
  I have a mid-2010 iMac with OS X Yosemite (10.10.2) installed on it. The issue that I'm having is that I'm getting a Software Update popup that reads:
  Now, how can I be asked to "update" what I ALREADY HAVE installed?? In other words it's a junk update.  I get this popup one to two times a week and I only go on my Mac perhaps 5 times a week.
Not long after updating to Java 8 Update 31 in maybe early Jan 2015 I got this popup.  I thought perhaps they had a typo on the "Update 31" part of the popup.  So I updated it a 2nd time on Jan 21st.  And now this happened today.
Does anyone have any ideas or suggestions to make this popup stop appearing for no reason?          - Rob

@ Linc Davis:
  I followed the link you gave.  And downloaded using the link on that page.  The page had a link "How to install" at:
http://java.com/en/download/help/mac_install.xml   After reading the instructions to the bottom of the page I saw a link to test the installation.  So to test if I already had installed the Java that I was now downloading; I clicked the test link.  And I got this:
So aparently I do not need to install the Java I downloaded at the link you gave as I already have it!  So we're back to square one.  Why is this occuring on my system?
