public boolean isAcontains(BitSet H){
  BitSet M=((BitSet)A.clone());
  M.and(H);
  return M.cardinality() == H.cardinality();
}

public boolean isAcontains ( BitSet H ) { BitSet M = ( ( BitSet ) A . clone ( ) ) ; M . and ( H ) ; return M . cardinality ( ) == H . cardinality ( ) ; }
does a part contain set h ?
