First off I'm using Ubuntu 14.04
I was following this video to set up a Java JDK and at the end he uses
java -version
to see his current version number. The Version I installed was 1.8.0_66 but mine returns
java version "1.7.0_79"
OpenJDK Runtime Environment (IcedTea 2.5.6) (7u79-2.5.6-0ubuntu1.14.04.1)
OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)
But when I check for the JAVA_HOME that seems to be correct
user@user:~$ $JAVA_HOME
bash: /usr/lib/java/jdk1.8.0_66: Is a directory
Where have I gone wrong? The additional resource he uses in the video is this and I feel like step 5 is maybe where things are going haywire, even though I do update the file name version before I run the script.
Any ideas? Anything is much appreciated thank you.
After digging around online I ran the line
update-alternatives --config java
which returned with
There are 3 choices for the alternative java (providing /usr/bin/java).
Selection Path Priority Status

* 0 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 auto mode

Press enter to keep the current choice[*], or type selection number:
I've tried entering in 1 and sudo 1 etc but the java version doesn't change. And it just redisplays the above code, without changing the default. How do I correctly enter this? If this is even how to do it. According to this I already had java installed in the jvm folder. Is it necessary to use the latest version of java or should I use this preinstalled version? I'm new to java so I'm not very experienced on what I need to be doing.
sudo update-alternatives --config javaand then enter 1..should do it..sudo update-alternatives --install /usr/bin/java java /usr/lib/java/jdk1.8.0_66/bin/java 1100
