java - Type Set does not take parameters - 


package set;  import java.util.*;  public class set  {    public static void main(string[] args)   {     string [] things = {"appple", "bob", "ham", "bob", "bacon"};     list<string> list = arrays.aslist(things);      system.out.printf("%s ", list);     system.out.println();      set<string> set = new hashset<string>(list);     system.out.printf("%s ", set);    }  }

when try run program keep getting error set declaration. doing wrong?

rename public class set class name doesn't hide java.util.set.

your custom set class doesn't take type parameters. that's why set<string> doesn't pass compilation.

for example:

package set;  import java.util.*;  public class settest  {     public static void main(string[] args)     {         string [] things = {"appple", "bob", "ham", "bob", "bacon"};         list<string> list = arrays.aslist(things);          system.out.printf("%s ", list);         system.out.println();          set<string> set = new hashset<string>(list);         system.out.printf("%s ", set);       }  }

Using Java 8 lambdas/transformations to combine and flatten two Maps -

i have 2 maps: map<a, collection<b>> mapab map<b, collection<c>> mapbc i transform them map<a, collection<c>> mapac , i'm wondering if there's smooth way lambdas , transformations. in particular case, collections sets, i'd solve problem collections in general. one thought had first combine 2 maps map<a, map<b, collection<c>>> , flatten it, i'm open approach. data notes: b should occur in value collection associated 1 a , , same true mapbc (a given c mapped 1 b ). result, there should 1 path given a given c , although there may a -> b mappings there no b -> c mappings , there may b -> c mappings there no corresponding a -> b mappings. these orphans don't appear in resulting mapac . for sake of comparison, here's example of purely imperative approach same problem: map<a, collection<c>> mapac = new hashmap<>(); (entry<a, collection<b>> entry...
