我试图将String值转换为long,并且得到：java.lang.NumberFormatException：对于输入字符串：“20110328094108069414”
我的代码：
String buyId = "PSFT_20110328114728073793";long bookId = Long.parseLong(buyId .replaceAll("PSFT_",""));
错误：
10:12:10,522 ERROR [STDERR] java.lang.NumberFormatException: For input string: "20110328094108069414"10:12:10,522 ERROR [STDERR] at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)10:12:10,522 ERROR [STDERR] at java.lang.Long.parseLong(Long.java:415)10:12:10,522 ERROR [STDERR] at java.lang.Long.parseLong(Long.java:461)10:12:10,522 ERROR [STDERR] at unilog.com.user.ejb.userDAOORCL.checkCWSUserReg(userDAOORCL.java:363)10:12:10,522 ERROR [STDERR] at unilog.com.user.ejb.userEJBBean.checkCWSUserReg(userEJBBean.java:141)10:12:10,522 ERROR [STDERR] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)10:12:10,523 ERROR [STDERR] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)10:12:10,523 ERROR [STDERR] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)10:12:10,523 ERROR [STDERR] at java.lang.reflect.Method.invoke(Method.java:585)10:12:10,523 ERROR [STDERR] at org.jboss.invocation.Invocation.performCall(Invocation.java:359)10:12:10,523 ERROR [STDERR] at org.jboss.ejb.StatelessSessionContainer$ContainerInterceptor.invoke(StatelessSessionContainer.java:237)10:12:10,523 ERROR [STDERR] at org.jboss.resource.connectionmanager.CachedConnectionInterceptor.invoke(CachedConnectionInterceptor.java:158)
最佳答案
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
