我通过这意味着“添加日期”来添加日期， 这是标准程序，但不幸的是我的 Pentaho 应用程序中断了c.setTime(dt);，我显然不知道原因，因为异常没有任何意义。
所以另一种选择是解析日期并提取月、年、日和 +1 到当天，但我必须处理Feburaryand odd months。我脑子里只有这两个选项。

谁能指导我其他选择？

此外，如果您使用的是 Kettle/Pentaho 数据集成，则可以使用该Calculator步骤。提供的计算之一是“日期 A + B 天”。我经常使用它，它对我来说一直很有效。

我遇到了同样的问题，这是对我有用的解决方案..

这是用户定义的 Java 类中的一个问题

这是在尝试访问在 try/catch 块之外的 try/catch 块中设置的变量时引起的（即，即使事先声明，但直到在 try/catch 中才设置，仍然会出现此错误）。

另一种方法是使用Joda time

DateTime dateTime = new DateTime(date);
dateTime = dateTime.plusDays(1);

尝试。

Calender cal=Calender.getInstance();

cal.add(Calender.DATE,1);

一个例子

    Calendar cal = Calendar.getInstance();
    System.out.println(cal.getTime());// out put Thu Aug 22 16:31:56 IST 2013
    cal.add(Calendar.DATE,1);
    System.out.println(cal.getTime());// out put Fri Aug 23 16:31:56 IST 2013

检查这个演示。

如果您以这种方式尝试，这应该可以正常工作。请留下评论或在此处发布您的代码，并带有例外。
