The GregorianCalendar is not displayed correctly inside the cells of the tablecolumn. When i use Strings, ints and doubles it works fine. When i run the application the cells containing dates show this java.util.GregorianCalendar[time=?,areFieldsSet=false,areAllFieldsSet=false,lenient=true,zone=sun.util.calendar.ZoneInfo[id="Europe/Berlin",offset=3600000,dstSavings=3600000,.. But
GregorianCalendar在表列的单元格内无法正确显示。 当我使用字符串，整数和双打时，它工作正常。 当我运行应用程序时，包含日期的单元显示了这一点 java.util.GregorianCalendar[time=?,areFieldsSet=false,areAllFieldsSet=false,lenient=true,zone=sun.util.calendar.ZoneInfo[id="Europe/Berlin",offset=3600000,dstSavings=3600000,.. 但我希望它在年 - 月 - 日显示 public class ProjectenController imple

How do I find the fractional difference in Days between two Joda-Time DateTime instances? Days.daysBetween(start, end).getDays() gives me a round number like 10/15 etc. What i need to get is exact value like 10.15 or 15.78 You might miss minutes due to the round off, if you use Hours.hoursBetween . Try this : (end.getMillis - start.getMillis() )/(1000*3600*24) Subtract the time in millis
如何找到两个Joda-Time DateTime实例之间天数的小数差异？ Days.daysBetween（开始，结束）.getDays（）给我一个像10/15等的整数。我需要得到的是像10.15或15.78的精确值 如果您使用Hours.hoursBetween，则可能会由于四舍五入而错过分钟。 试试这个：（end.getMillis - start.getMillis（））/（1000 * 3600 * 24） 以毫秒为单位减去时间并按每天毫秒数除数： double diff = (end.getMillis() - start.getMillis()) /

I trying to parse a data in a MySql Format, I ran across SimpleDateFormat . I can get the proper day and month, but I got a strange result for the year : date = 2009-06-22; SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd"); Date d = sdf.parse(date); System.println(date); System.println(d.getDate()); System.println(d.getMonth()); System.println(d.getYear()); Outputs : 2009-06-22 22
我试图解析MySql格式的数据，我碰到了SimpleDateFormat 。 我可以得到适当的一天和一个月，但是我在这一年得到了一个奇怪的结果： date = 2009-06-22; SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd"); Date d = sdf.parse(date); System.println(date); System.println(d.getDate()); System.println(d.getMonth()); System.println(d.getYear()); 产出： 2009-06-22 22 OK 5 Hum...

It has always bothered me that the only way to copy a file in Java involves opening streams, declaring a buffer, reading in one file, looping through it, and writing it out to the other steam. The web is littered with similar, yet still slightly different implementations of this type of solution. Is there a better way that stays within the bounds of the Java language (meaning does not involve
它一直困扰着我，用Java复制文件的唯一方法就是打开流，声明一个缓冲区，读入一个文件，循环遍历它，并将它写入其他流。 网络上散布着类似的，但仍然稍有不同的这种类型的解决方案的实现。 是否有更好的方法保持在Java语言的范围之内（意思是不涉及执行特定于OS的命令）？ 也许在一些可靠的开源工具包中，这至少会掩盖这个潜在的实现并提供单线解决方案？ 正如上面提到的工具包一样，Apache Commons IO是要走的路，特别是F
I'm using the jsr166y ForkJoinPool to distribute computational tasks amongst threads. But I clearly must be doing something wrong. My tasks seem to work flawlessly if I create the ForkJoinPool with parallelism > 1 (the default is Runtime.availableProcessors(); I've been running with 2-8 threads). But if I create the ForkJoinPool with parallelism = 1, I see deadlocks after an unpred
我使用jsr166y ForkJoinPool在线程之间分配计算任务。 但我显然一定会做错事。 我的任务似乎完美地工作，如果我创建并行度大于1的ForkJoinPool（默认是Runtime.availableProcessors（）;我已经使用2-8个线程运行）。 但是，如果我创建并行度= 1的ForkJoinPool，则会在无法预测的迭代次数后看到死锁。 是的 - 设置并行度= 1是一种奇怪的做法。 在这种情况下，随着线程数量的增加，我正在分析并行算法，并且我想将并行版本
I have a webservice I am trying to build a client for. I have the following wsdl: http://www.cmicdataservices.com/datacenter/service.asmx?wsdl It requires authentication. Looking at the WSDL description I see no method that takes an authentication object, nor username and passwords as arguments. Using Netbeans I have generated jax-ws sources for the WSDL. I however can not figure out what
我有一个web服务，我正在尝试构建一个客户端。 我有以下wsdl： http://www.cmicdataservices.com/datacenter/service.asmx?wsdl 它需要认证。 查看WSDL描述，我看不到任何采用身份验证对象的方法，也不会将用户名和密码作为参数。 使用Netbeans我已经为WSDL生成了jax-ws源代码。 然而，我不知道在那之后要做什么。 使用soapui我可以连接到webservice并运行所有的方法。 但是，我想再次将其构建到可以在没有我的交互的

I am trying to create a server - client bundle that will let me send simple messages with ssl support. I am quite new at java and i can't figure out what my problem is. I am running the server and client programs at 2 computers at the same network and i can send messages. My problem is that when i capture the messages with wireshark the protocol is TCP and i can read the messages About the
我正在尝试创建一个服务器 - 客户端软件包，它允许我发送带有SSL支持的简单消息。 我在java中很新，我无法弄清楚我的问题是什么。 我在同一网络的两台电脑上运行服务器和客户端程序，我可以发送消息。 我的问题是，当我用wireshark捕获邮件的协议是TCP，我现在可以读取关于证书的消息，我已经用openssl创建了所有的证书，并且已经使用keytool将它们转换为.jks。 Myca.jks是自签名ca的证书，我用这个证书签署了服务器和客户端
