I have a program that I'm working on where I'm stuck on what to do next. I've got the java program to read and display a text file and what I need it to do after that is count the number of unique word PAIRS that appear in the text. I've attached the program I have put together along with the output that is desired. I also attached the text file that the program reads from to display the output.
I'd really like to know what coding I'll need to get the output, since I'm not really sure what way to go.

The easiest way to do that would be to use a Java HashMap. You can create a java hasmap as below
HashMap<String, HashMap<String, Integer>> outerHashMap = new HashMap<HashMap<String, Integer>>();
HashMap<String, Integer> innerhashMap = new HashMap<String, Integer>();

So the algorithm would be something like this

Read next word from scanner
Check if word exists in outerHashmap; if not add a new innerhashmap.
If it exists, pick up the next word and check if it exists in the innerhashmap. If not, then add a new entry in the hashmap.
If the entry exists in inner hash map, then increment the value integer by 1.
