java - using varargs and Maps -

i want add object map gives error. maybe have use lists there getname() method used map. have check if has duplicate value , throw exception if found

public class handleapplications {      map<string,name> names = new hashmap<>();      public void addnames(string... names) throws exception{         name c = new name(names);          if(names.containsvalue(names)){             throw new applicationexception();         }          names.put(names,c) //this line gives error     }      public name getname(string name) {         return names.get(name);     } } 

i think need -

public void addnames(string... names) throws exception {     (string s : names) {         name c = new name(s);         this.names.put(s, c);     } } 

consider changing variable names. variable names same, had use this.names refer map.
