In my experience, if you've got a JRE installed, then install a JDK, the path for java.exe etc. will stay pointing at the JRE.
I hope I've answered your two questions, why are they different (because of the order of your path), and how to make the latest one the one that executes (by either installing the latest JRE or else fixing your path by hand) in the details below:
$ where java
C:Program Files (x86)Common FilesOracleJavajavapathjava.exe
C:Program Files (x86)Javajdk1.8.0_121binjava.exe
C:ProgramDataOracleJavajavapathjava.exe
$ which java [btw, which is a GNU tool, not built into Windows]
C:Program Files (x86)Common FilesOracleJavajavapathjava.EXE
$ path
PATH=C:Program Files (x86)Common FilesOracleJavajavapath;C:Program Files (x86)Javajdk1.8.0_121bin;
$ "C:Program Files (x86)Common FilesOracleJavajavapathjava.exe" -version
java version "1.8.0_201"
Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
Java HotSpot(TM) Client VM (build 25.201-b09, mixed mode)
$ "C:Program Files (x86)Javajdk1.8.0_121binjava.exe" -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) Client VM (build 25.121-b13, mixed mode, sharing)
(Pretending for the moment my JDK version of java was the newer one) I could update the JRE separately and it would probably fix things by putting the correct new version in Common Files for me, or I might just edit my path to put C:Program Files (x86)Javajdk1.8.0_121bin; in front of C:Program Files (x86)Common FilesOracleJavajavapath;
