java - 将字符串数组转换为 BigDecimal 数组

Question

我正在尝试将 String[] 转换为 BigDecimal[] 但出现 java.lang.NumberFormatException

这是我的代码

BigDecimal montanttt[] = new BigDecimal[montantt.length];
        for (int i = 0; i < montantt.length; i++) {
            montanttt[i] = new BigDecimal(montantt[i]);
            System.out.println(montanttt[i]);
        }

Answer 1

您应该在 for 循环中使用 try/catch 检查异常:

for (int i = 0; i < montantt.length; i++) {
    try {
        montanttt[i] = new BigDecimal(montantt[i]);
        System.out.println(montanttt[i]);
    } catch (NumberFormatException e) {
        System.out.println("Exception while parsing: " + montantt[i]);
    }
}
