Ok guys so I have figured out how to do the treemap now and it sorted the entrys in alphabetical order and prints thee averages. Next I need to sort Treemap based on the values.
I think I have to somehow pass the Treemap to an arraylist, sort the arraylist and then pass it to a hashmap and then print the hashmap but this is really confusing..
Do I need to make a new class that implements comparable or something?
Ok abit of an update basically I type this.
System.out.println(myMap.values()); and it prints out
[1.0, 7.5, 2.9, 5.0]
I need to pass myMap.values() to an Array so I can sort that array and then print it out again so the values will be in highest order first but I just can't figure out the line of code that will change map.values() into an array
Not an advanced topic. Moving to New to Java.

If it isn't advanced maybe you can answer it?Quote:

If it's only for display you could Collections.sort() that array.
That's assuming it's a List, of course.
You can't. Plenty of workarounds though. Did you try anything Google suggested?
