I have a ArrayList whose one of the fields is BigDecimal . I can not do this sum iteratively with a loop. Can anyone give a tip on how to perform this operation?
If it were a% common%, it would do the following, but using the bigdecimal, I can not think of a solution:
for(..){
valorTotal += lista.get(i).getValorItem();
}
Adriano, in% with% it is impossible to use the BigDecimal operator. Use + :
valorTotal = BigDecimal.ZERO;
for (...) {
valorTotal = valorTotal.add(lista.get(i).getValorItem());
}
If you are in Java 8, you can use add() (very cool):
valorTotal = lista.stream()
.map(NomeDaSuaClasse::getValorItem)
.reduce(BigDecimal.ZERO, BigDecimal::add);
