After spending many hours searching the Internet and following many different instructions and typing thousands of commands into the terminal with the process always failing (usually at the last input), I've finally found a way of installing Java on Ubuntu.
To run Java programs you need to have the Java Runtime Environment (JRE) installed. You can see whether it is already installed by checking the version: In the Terminal (search for 'Terminal'), type:
$ java -version
If the required version of Java is not already installed, try running the Software Updater and check again, otherwise install the required version from a different repository:
$ sudo apt-add-repository ppa:openjdk-r/ppa
$ sudo apt-get update
$ sudo apt-get install openjdk--jre
$ sudo update-alternatives --config java
[Choose version by entering the Selection Number of the required version]
This method will also probably work for Debian and Linux Mint.
If you want to develop programs you will, of course, also need the Java Development Kit installed, so enter:
$ sudo apt-get install openjdk-8-jdk
instead of:
$ sudo apt-get install openjdk-8-jre

Paired Comparisons is a decision making and prioritizing tool.
In addition to a description of the tool, and an example of its use, there is also an embedded program which will take out much of the hard work in using the tool.

Texts from schools to parents about tests and homework can boost secondary pupils' maths grades by the equivalent of a month in class.
Texting can also cut pupil absence, according to the Queen's University Belfast evaluation.
The programme involved 15,697 pupils in 29 schools across England, half of whose parents were sent texts. The pupils who took part in the study were from Year 7 - the first year of secondary school, Year 9 and Year 11 - the GCSE year. In each school, either the parents of the Year 11 group or the Year 7 and Year 9 groups were allocated to receive the texts.
The parents of about half the pupils involved in the trial were sent roughly one text a week during the school term, for a year starting in September 2014. Overall, the programme amounted to about 30 texts over the year.
They included the dates of tests and warnings about missed homework as well as details about what the children had learnt during the day, aiming to prompt conversations at home about school.
The researchers carried out baseline tests to determine pupils' abilities at the beginning of the year and used figures from the National Pupil Database to determine their progress.
The researchers found the effect of the intervention was not statistically significant in English and science.
