Converting Range Statements To Sets In Java

I am trying to Extract the ranges of Variables from a Text File. I extracted lines of the forms X in 1..10 Y in 12..50 Z in 0..19 / 66/ 95..100 Where X in 1 ..10 states that X takes values from set 1 to 10 Similarly for Y and for Z its a Union of different ranges of the values (0 to 19, union 66,union 95 to 100)

I want to Map these Variables to their respective sets using Hashmap where Key is Variable name and value will be a Set. My Hashmap Signature is HashMap> hm=new HashMap>();

Java Code:

while((line=br.readLine())!=null) {
Matt=Patt.matcher(line);
if(Matt.find()) {
//System.out.println(line);
String []s=line.split(" ");

[Code] .....

I am stuck at extracting the variables ranges from these plain strings.
