我的课.
class MyLoan {
private Long loanId;
private BigDecimal loanAmount;
private BigDecimal totalPaid;
....
}
class Customer {
private Long loanId;
private List<MyLoan> myLoan;
}
我想迭代Customer中的myLoan，然后计算totalPaid.
我的逻辑是"如果loanId是23491L或23492L，那么将这两个loanId中的loanAmount相加，并将totalPaid的值设置为loanId 23490L".totalPaid的值是always showing as zero，我的逻辑如下.
想要使用Java8流，但在使用流时无法写入多个条件.
BigDecimal spreadAmount;
for (MyLoan myloan: customer.getMyLoan()) {
if (myloan.getLoanId() == 23491L || myloan.getLoanId() == 23492L) {
spreadAmount = spreadAmount.add(myloan.getLoanAmount());
}
if (myloan.getLoanId() == 23490L) {
myloan.setTotalPaid(spreadAmount);
}
}
