get day month year from java.sql.date
提问by Tarounen
My question is simple my SQLquery from java returns a date and assign it to a java.sql.Datevariable.
我的问题很简单，我的SQLjava 查询返回一个日期并将其分配给一个java.sql.Date变量。
however i want to get each of the day, month and year as int. It seems that the methods getDay(),getMonth()are deprecated.
但是我想将每一天、每一个月和每一年都作为整数。似乎方法getDay(),getMonth()已被弃用。
Are there any other way to achieve this?
有没有其他方法可以实现这一目标？
what i tried for testing is:
我尝试测试的是：
String date = "2015-04-12";
java.sql.Date dat = java.sql.Date.valueOf(date);
now i want year, month and day in an int variable each.
现在我想要年、月和日在一个 int 变量中。

You can do the following:
您可以执行以下操作：
String date = "2015-04-12";
java.sql.Date dat = java.sql.Date.valueOf(date);
//create calander instance and get required params
Calendar cal = Calendar.getInstance();
cal.setTime(dat);
int month = cal.get(Calendar.MONTH);
int day = cal.get(Calendar.DAY_OF_MONTH);
int year = cal.get(Calendar.YEAR);

Since java.sql.Dateextends java.util.Dateyou could use its inherited toLocalDate()method to get instance of LocalDate(available since Java 8) which supports many get...()methods like
由于java.sql.Date扩展，java.util.Date您可以使用其继承的toLocalDate()方法来获取LocalDate支持许多get...()方法的实例（自 Java 8 起可用），例如
String date = "2015-04-12";
java.sql.Date dat = java.sql.Date.valueOf(date);
LocalDate localDate = dat.toLocalDate();
System.out.println(localDate.getDayOfMonth());
System.out.println(localDate.getMonthValue());
System.out.println(localDate.getYear());
Output:
输出：
12
