class Bill {
    int billNo;
    double totalAmount;

    // Constructor, getters, and setters omitted for brevity
}

// Assuming bills is a List<Bill>
for (Bill bill : bills) {
    if (bill.getBillNo() == targetBillNo) {
        bill.setTotalAmount(newTotalAmount);
        break; // Exit loop once the bill is found and updated
    }
}
