Java compiler version and java version is different

Question

I am trying to run a compiled java class and getting errors but when I checked my java environments it points to different version.

Javac –version gives me 1.8.0

Java –version gives me 1.6.2

The Java_home and path is pointing to the 1.8 version.

Please help.
