I want to count days between two date, I found some solutions on the net but the problem is in my NetBeans the GregorianCalendar is not available. So cant calculate the days. Can anyone help ?

推荐答案

在Java Micro Edition中，您没有GregorianCalendar，因此必须使用:

In Java Micro Edition you don't have GregorianCalendar, so you have to use:

Date startDate, endDate;
...
int days = (int) ((endDate.getTime() - startDate.getTime())  
    / (1000 * 60 * 60 * 24)); 

日期returns the number of milliseconds since January 1, 1970, 00:00:00 GMT
