java check if list of object contains object with concrete name

I have list of objects:

List<City> cities = city.getList();

I would like to remove duplicates (where duplicates mean objects with the same value of parameter name and different (id, and other parameters);

I have code for that:

for(City c: cities) {
    System.out.println("analise " + c.name);
    if(!temp.contains(c)) {
        temp.add(c);
    }
}

I've wrote for that hashCode() and equals() method:

@Override
public int hashCode() {
    return id.hashCode();
}

...

  @Override
    public boolean equals(Object other) {
        if (other == null) return false;
        if (other == this) return true;
        if (!(other instanceof GenericDictionary))return false;
        GenericDictionary otherMyClass = (GenericDictionary) other;
        if(this.name == otherMyClass.name) {
            return true;
        } else {
            return false;
        }
    }

But it dosnt apply it. It use object.equals() method instead of mine
