输入数字时的NumberFormatException

Question

我想从我的提案类中获取数据并将其显示在我的购物车类中，但我一直收到NumberFormatException的错误。

我尝试通过输入文字或数字来解决它，但我仍然得到同样的错误。请帮助。

Answer 1

你要

java.lang.NumberFormatException: For input string: ""

这意味着您正在尝试将空字符串转换为整数

中的order.getTotalPremium()或order.getProposalId()为空

total+=(Integer.parseInt(order.getTotalPremium()))* (Integer.parseInt(order.getProposalId()));

在日志中打印并调试它们。

Answer 2

可能这些order.getTotalPremium（）或order.getProposalId（）返回空字符串 所以请检查以下代码
