How to compare two dates in Java by incrementing Date?
问题
String dt = "2008-01-01"; // 开始日期
String et = "2008-01-10";
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
Calendar c = Calendar.getInstance();
Date startDate = sdf.parse(dt);
Date endDate = sdf.parse(et);
Date incDate;
// dt 现在是新日期
do {
System.out.println("嘿，我被调用了......");
c.setTime(sdf.parse(dt));
c.add(Calendar.DATE, 1); // 要添加的天数
dt = sdf.format(c.getTime());
System.out.println("增加的日期：" + dt);
incDate = sdf.parse(dt);
} while (endDate.compareTo(incDate) >= 0);

首先，您应该开始使用像@TomStroemer指出的较新类。
我认为您想要获取两个日期之间的天数？
LocalDate startDate = LocalDate.parse("2008-01-01");
LocalDate endDate = LocalDate.parse("2008-01-10");
Period period = Period.between(startDate, endDate);
System.out.println(period.getDays());
应该输出8，因为它们之间有8天。尚未测试该代码。
请查阅以下文档：
Period: https://docs.oracle.com/javase/8/docs/api/java/time/Period.html
LocalDate: https://docs.oracle.com/javase/8/docs/api/java/time/LocalDate.html
同时请提供更多细节。

first you should start using the newer classes like @TomStroemer pointed out.
I think you want to get the number of days between the two dates ?
LocalDate startDate = LocalDate.parse("2008-01-01");
LocalDate endDate = LocalDate.parse("2008-01-10");
Period period = Period.between(startDate, endDate);
System.out.println(period.getDays());
Should print 8 because there are 8 days between. Haven't tested that code.
See the following docs:
Period: https://docs.oracle.com/javase/8/docs/api/java/time/Period.html
LocalDate: https://docs.oracle.com/javase/8/docs/api/java/time/LocalDate.html
And really provide more details.
