JAVA获取当前年份，⽉份、⽇期、⼩时、分钟、秒等
import java.util.Calendar;
public class Main {
public static void main(String[] args) {
Calendar cal = Instance();
int day = (Calendar.DATE);
int month = (Calendar.MONTH) + 1;
int year = (Calendar.YEAR);
int dow = (Calendar.DAY_OF_WEEK);
int dom = (Calendar.DAY_OF_MONTH);
int doy = (Calendar.DAY_OF_YEAR);
int hour = (Calendar.HOUR_OF_DAY);
int minute = (Calendar.MINUTE);
int second = (Calendar.SECOND);
System.out.println("当期时间: " + Time());
System.out.println("⽇期: " + day);
System.out.println("⽉份: " + month);
System.out.println("年份: " + year);
System.out.println("⼀周的第⼏天: " + dow);  // 星期⽇为⼀周的第⼀天输出为 1，星期⼀输出为 2，以此类推
System.out.println("⼀⽉中的第⼏天: " + dom);
System.out.println("⼀年的第⼏天: " + doy);
System.out.println("⼩时: " + hour);
System.out.println("分钟: " + minute );
System.out.println("秒: " + second );java64位
