如何比较日期是否大于其他日期？

Question

I am taking the current date in ymd format as below :

  String date = new SimpleDateFormat("yyyy-MM-dd", Locale.getDefault()).format(new Date());

I also have a date as String as below :

String futureDate = "2022-03-07"

How can I know if the current date is less than or greater than future date ?

I tried to use compareTo() function, but was unable to compare the two dates.

要比较日期，您可以转换为 Date 并使用：

final Date other = simpleDateFormat.parse("2022-03-07");
final Date now = new Date();

if (other.after(now)) {
    // In the future!
} else if(other.before(now)) {
    // In the past!
} else {
    // In the present!
}
