java.math.BigDecimal不能强制转换为java.lang.String吗? [英] java.math.BigDecimal cannot be cast to java.lang.String?

问题描述

我试图添加数据类型(货币)的行值，其中像这样在Jtable中自动形成十进制后的零 55.0000 28.0000 60.0000 20.0000 50.0000

I am trying to add row values of datatype(money) in which zeros after decimal are automatically formed in Jtable like these 55.0000 28.0000 60.0000 20.0000 50.0000

在运行时日志中显示此错误

on runtime log showing this error

java.math.BigDecimal无法转换为java.lang.String

java.math.BigDecimal cannot be cast to java.lang.String

这是来自Jtable的行添加代码

Here is the code for rows addition from Jtable

        double total = 0;
        for(int i = 0; i<table.getRowCount(); i++){
            double amount = Double.parseDouble((String) table.getValueAt(1, 6) );
            total+=amount;
        }
        totalSum.setText(String.valueOf(total));

推荐答案

尝试如下操作:

BigDecimal total = BigDecimal.ZERO;
for (int i = 0; i < table.getRowCount(); ++i) {
    final BigDecimal amount = (BigDecimal)table.getValueAt(i, 6);
    total = total.add(amount);
}
totalSum.setText(total.toString());
