Java HashSet contains Object -

i made own class overridden equals method checks, if names (attributes in class) equal. store instances of class in hashset there no instances same names in hashset.

my question: how possible check if hashset contains such object. .contains() wont work in case, because works .equals() method. want check if same object.

edit:

package testprogram;  import java.util.hashset; import java.util.set;  public class example {     private static final set<example> set = new hashset<example>();     private final string name;     private int example;      public example(string name, int example) {         this.name = name;         this.example = example;         set.add(this);     }      public boolean isthisinlist() {         return set.contains(this);         //will return true if equal instance in list         //but should not         //it should return true if object in list     }      public boolean remove() {         return set.remove(this);     }      //override equals , hashcode } 

sorry, english skills not well. please feel free ask again if don't understand mean.

in situation, way tell if particular instance of object contained in hashset, iterate contents of hashset, , compare object identities ( using == operator instead of equals() method).

something like:

boolean isobjectinset(object object, set<? extends object> set) {    boolean result = false;     for(object o : set) {      if(o == object) {        result = true;        break;      }    }     return result; }
