java.lang.NumberFormatException:对于输入字符串:"20110328094108069414"

Question

我试图将String值转换为long,并得到: java.lang.NumberFormatException: For input string: "20110328094108069414"

我的代码:

  String buyId  = "PSFT_20110328114728073793";
  long bookId  = Long.parseLong(buyId  .replaceAll("PSFT_",""));

错误:

Answer 1

允许的最大值long是

  9223372036854775807L

你的价值是:

  20110328094108069414L

你不能用long这个.您可以使用BigInteger,但考虑到用例,我认为这String将是最合适的类型.(我无法想象您需要对book id进行整数运算,如果需要进行数值比较,您可以轻松实现自定义Comparator来对十进制字符串执行此操作.)

Answer 2

我认为你需要使用BigInteger或BigDecimal

例如:

BigInteger bi;

String buyId  = "PSFT_20110328114728073793";
bi  = new BigInteger(buyId.replaceAll("PSFT_",""));

使用NumberFormatException添加try-catch块
