Setting hashmap value via forloop from array of strings (first value to key, second to value and so on..)

Java

I have three "sets" of `String` in a form:
1. Set<string> genderSet
sort:bestsellerRating:gender:Female,:bestsellerRating:gender:Male
2. Set<string> ageSet
sort:bestsellerRating:age:0 - 6 Months, :bestsellerRating:age:6 - 12 Months :bestsellerRating:age:12 - 14 Months
3. Set<string> priceSet
sort:bestsellerRating:price:£0-£19.99, :bestsellerRating:price:£200-£299.9

Want to create a function which returns a `string` similar to following:

Output: sort:bestsellerRating:gender:Female:gender:Male:age:0 - 6 Months:age:6 - 12 Months:age:12 - 14 Months:price:£0-£19.99:price:£200-£299.9

Dont want to play with string as its not a good approach.
Reason: genderSet, ageSet and priceSet can be anything which is : seperated

Wish to achieve this using `HashMap`



**Help Needed**: Need the map to be formed like this: queryMap(sort, bestSelling), queryMap(gender, [Male,Female]), queryMap(age, [0 - 6 Months, 6 - 12 Months, 12 - 14 Months]), queryMap(price, [£0-£19.99,£200-£299.9]) from genderList[sort,bestseller,gender,male,gender,female] ageList[sort,bestselling,age,0 - 6 Months,age,6 - 12 Months,age,12 - 14 Months] and priceList[sort,bestselling,price,£0-£19.99,price,£200-£299.9]

What I have tried:

public String getQuery(final Form Form)
{
private static final String FACET_SEPARATOR = ":";

final Map<string, set<string="">> queryMap = new HashMap<string, set<string="">>();

final Set<string> giftFinderQuerySet = new HashSet<string>();

final Set<string> valueSet = new HashSet<string>();

final Set<string> genderSet = form.getGenderSet();

final Set<string> ageSet = form.getAgeSet();

final Set<string> priceSet = form.getPriceSet();


for (final String gender : genderSet)
{
final String[] genderList = gender.split(FACET_SEPARATOR);// This will bring first- [sort, bestsellerRating, gender, Female] at one time, then [bestsellerRating, gender, Male] later in the next loop

for (final String genderSplittedValue : genderList)
{
//valueSet.add(genderList[+1]);
queryMap.put(genderSplittedValue, valueSet); // Issue here: Need the map to be formed like this: queryMap(sort, bestSelling), queryMap(gender, [Male,Female])

}


}

for (final String age : ageSet)
{
final String[] ageList = age.split(FACET_SEPARATOR);//Similar list like genderList

for (final String ageSplittedValue : ageList)
{
queryMap.put(genderSplittedValue, ageList[+1]); // Similar issue like above

}


}

for (final String price : priceSet)
{
final String[] priceList = price.split(FACET_SEPARATOR);//Similar list like genderList

for (final String priceSplittedValue : priceList)
{
queryMap.put(priceSplittedValue, priceList[+1]); // Similar issue like above

}


}

Now once we have the map ready, then there is no issue in further code

for (Map.Entry<string,key> entry : queryMap.keySet())
{
String key = entry.getKey();
String value = entry.getValue();
giftFinderQuerySet.add(key+FACET_SEPARATOR+value);
}

for (final String query : giftFinderQuerySet)
{
searchQuery = searchQuery.concat(query);
}
return searchQuery;
}//End of method
