HashSet contains substring

Question

I have a HashSet of Strings in the format: something_something_name="value"

Set<String> name= new HashSet<String>();

Farther down in my code I want to check if a String "name" is included in the HashSet. In this little example, if I'm checking to see if "name" is a substring of any of the values in the HashSet, I'd like it to return true.

I know that .contains() won't work since that works using .equals(). Any suggestions on the best way to handle this would be great.

Answer 1

With your existing data structure, the only way is to iterate over all entries checking each one in turn.

If that's not good enough, you'll need a different data structure.
