Trying to use Optional.ofNullalbe in java 8 to replace the below traditional if else code

String result = null;
if ( a!= null ) {
  result = a.getVal1();
  if(result == null) {
    result = a.getVal2();
  }
}

and ended up like below to achieve the result. Is there a better way of doing it.

result = Optional.ofNullable(a)
.map(A::getVal1)
.orElse(
  Optional.ofNullable(a)
  .map(A::getVal2)
  .orElse(null)
);
