Sarvar Nishonboev :
I have the following class:
public class Transfer {
private String fromAccountID;
private String toAccountID;
private double amount;
}
and a List of Transfers:
....
private List<Transfer> transfers = new ArrayList<>();
I know how to get one transfer history:
transfers.stream().filter(transfer ->
transfer.getFromAccountID().equals(id)).findFirst().get();
But I want to get by fromAccountID and toAccountID, so the result will be a List of Transfers. How can I do that with Java8 Stream filter functions?
Ousmane D. :
filter by the two properties and collect into a list.
List<Transfer> resultSet =
transfers.stream().filter(t -> id.equals(t.getFromAccountID()) ||
id.equals(t.toAccountID()))
.collect(Collectors.toList());
