java 获取当前年份 月份 日期

import java.util.Calendar;

System.out.println("Current Date: " + cal.getTime());
System.out.println("Day: " + day);

System.out.println("Year: " + year);
System.out.println("Day of Week: " + dow);
System.out.println("Day of Month: " + dom);

}
}

int year = currTime.getYear();//年

int month = currTime.getMonth()+1;//月

int week = currTime.getDay(); //星期几

int day = currTime.getDate();//日

String curTime = formatter.format(currTime);
