How to create generic array of class with two type parameter and constrain?

Question

I'm trying to create generic array in java but it results in error. Can any one help me on this?

Please find my code below:

public class GenericArrayTest<TKey extends Comparable,TValue>
                                   implements Iterable<Map.Entry<TKey,TValue>> {
  private TKey[] _arrayCOll;

  public void test(){
    _arrayCOll = new TKey[10];//error "Cannot create a generic array of TKey"
  }

  @Override
  public Iterator<Entry<TKey, TValue>> iterator() {
        // TODO Auto-generated method stub
        return null;
  }

}

Note: I could not know the class type so that i could not use the below solution How to create a generic array in Java?

Thanks in advance. Sarath
