Question

我需要有关如何在更新数据库之前从字符串中删除$符号的帮助目前在我的应用程序中，默认情况下从结尾添加$作为第一个字符。我需要知道如何删除它，因为我在更新数据库时遇到了Big Decimal错误。

String postagePaid = (String) request.getParameter("tPostagePaid");
            String insuranceFees = (String) request.getParameter("tInsuranceFees");
            String registeredFees = (String) request.getParameter("tRegisteredFees");
            String codFees = (String) request.getParameter("tCODFees");
            String insRegisteredCODFees = (String) request.getParameter("tInsuranceFees");
            System.out.println("insurance Fee: " + insuranceFees);
            if (postagePaid != null && !insuranceFees.isEmpty()) { // postage paid amount
                claim.setClPostagePaidAmt(new BigDecimal(postagePaid));
            }
            if (insuranceFees != null && !insuranceFees.isEmpty()) { // Insurance Fees
                claim.setClInsuranceFee(new BigDecimal(insuranceFees));
            }
            if (registeredFees != null && !insuranceFees.isEmpty()) { // Registered Fees
                claim.setClRegisteredFee(new BigDecimal(registeredFees));
            }
            if (codFees != null && !insuranceFees.isEmpty()) { // COD Fees
                claim.setClCodFee(new BigDecimal(codFees));
            }
            claim.setClInsRegCodAmt(null);

你可以尝试两件事。

str = str.replace("$","");

OR

str = str.substring(1);

原因
你只想删除第一个字符。
