SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
Date beginDate = sdf.parse(begin);
Date endDate = sdf.parse(end);利用SimpleDateFormat类可以把String转换成Date,即问题转换成判断时间是否在两个Date之间。
两种方法:
1用Date类的compareTo方法
2把时间统一转换为long型判断(Date类有getTime方法)
int month,
int date,
int hrs,
int min)
before
public boolean before(Date when)
Tests if this date is before the specified date. Parameters:
when - a date.
Returns:
true if and only if the instant of time represented by this Date object is strictly earlier than the instant represented by when; false otherwise.--------------------------------------------------------------------------------after
public boolean after(Date when)
Tests if this date is after the specified date. Parameters:
when - a date.
Returns:
true if and only if the instant represented by this Date object is strictly later than the instant represented by when; false otherwise.
