I have to model this table: ————————————– | range | X<10 | 10<X<30 |

  • 0

I have to model this table:

--------------------------------------
| range  | X<10  | 10<X<30 | 30<X<50 |
|--------|---------------------------|
|  Y<5   |  HIGH |  MIDDLE | LOW     |
|------------------------------------|   
| 5<Y<10 | MIDDLE|  LOW    | HIGH    |
|____________________________________|

So I have to model it in a method that takes 2 parameters (X and Y) and return the correct value based on this table.

I thought on a map based implementation, but maybe this is not the best way.
How would you model it?

Kind regards
Massimo

    How about two maps?

    Map<Range, Map<Range, String>>()

    The Range will hold 2 integers (lower and upper bounds) , you will need to implement equals() and hashcode() in order for the Range to fit the `Map’ nature.

    So, the first Map will filter by X and the 2nd Map fill get the value (HIGH, LOW, etc)
