I just installed `Fedora 19` and managed to get `FedoraUtils` installed. So I chose `java oracle`. after installation I could see in the `FedoraUtils` list that `oracle java (installed)` but I can't see the Oracle Java anywhere.

As an Ubuntu user I would run the `update-java-alternatives -l` command but it didn't work. Below is the output of `alternatives --list`:

I don't remember typing openJDK but apparently it's installed. I would really like to find out where's `oracle-java`. I don't mind having the 2. When I check for the version in order to get the default `java`:

 [joseph@localhost ~]$ java -version
 java version "1.7.0_40"
 Java(TM) SE Runtime Environment (build 1.7.0_40-b43)
 Java HotSpot(TM) 64-Bit Server VM (build 24.0-b56, mixed mode)


- *Question 1* : Where is oracle java installed 
- *Question 2* : How to check default java in fedora 
- *Question 3* :I will like to set up system environment for JAVA_HOME, how does it work in `/etc/environment`?
