I was installing Spark on my Ubuntu 14.04 and it seemed to be going smoothly for quite a while then bombed with I have previously installed and checked Scala... and see details of Java at bottom..

I have Java installed:
tom@tom-sam:~$ java -version
java version "1.7.0_85"
OpenJDK Runtime Environment (IcedTea 2.6.1) (7u85-2.6.1-5ubuntu0.14.04.1)
OpenJDK 64-Bit Server VM (build 24.85-b03, mixed mode)
Any ideas??

You have the java runtime installed (the JRE). You need the JDK (Java Developer Kit). You can install the Oracle JDK, or the OpenJDK. For the OpenJDK, it should be as simple as
$ sudo apt-get install default-jdk
For the Oracle JDK, it's only a little more involved,
$ sudo apt-get install python-software-properties
$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
Then one of
$ sudo apt-get install oracle-java6-installer
or
$ sudo apt-get install oracle-java7-installer
or
$ sudo apt-get install oracle-java8-installer
For Java 6, 7 or 8 respectively.
