fatherazrael :
Initially code was :
if(!Objects.equals(src.getApplicationItemCost(), dest.getApplicationItemCost())){
log.info("Difference")
}
Output:
getApplicationItemCost: src:0.0| dest:0
Difference
ApplicationItemCost is of type BigDecimal.
If I use compareTo then I have to explicitly check nulls like :
LOG.info("getApplicationItemCost: src:" + src.getApplicationItemCost() + "| dest:" + dest.getApplicationItemCost());
if((src.getApplicationItemCost()==null && dest.getApplicationItemCost()!=null)
|| (src.getApplicationItemCost()!=null && dest.getApplicationItemCost()==null)
|| !Objects.equals(src.getApplicationItemCost(), dest.getApplicationItemCost())
|| src.getApplicationItemCost().compareTo(dest.getApplicationItemCost())!=0 )
Any suggestion to compare 0.0 and 0. Why is this difference? (May be database has Number field and when converted to big decimal it does not show 0.0?)
Andy Turner :
Build a comparator:
Comparator<BigDecimal> c = Comparator.nullsFirst(Comparator.naturalOrder());
(Or nullsLast, it doesn't matter if you're only ever comparing to zero).
Then:
if (c.compare(first, second) != 0) {
// ...
}
