What version am I actually running, and how to I get rid of all older versions and just keep 1.7? Also, terminal command "which java" returns /usr/bin/java. I'm just starting to learn java and want to be sure I can actually use the features of 1.7
The Oracle Java 1.7 JRE is a web plugin only. If you want to develop Java applications, you need the JDK.
Found and installed JDK 7. Thanks.
