使用Java日历获取月份和年份的星期
要使用Calendar类，请导入以下程序包。
import java.util.Calendar;
创建一个Calendar类对象。
Calendar cal = Calendar.getInstance();
现在，使用以下字段获取月份和年份的星期。
Calendar.WEEK_OF_MONTH Calendar.WEEK_OF_YEAR
以下是一个示例。
示例
import java.util.Calendar;
public class Demo {
public static void main(String[] args) {
Calendar cal = Calendar.getInstance();
// current date and time
System.out.println(cal.getTime().toString());
// date information
System.out.println("\nDate Information..........");
System.out.println("Year = " + cal.get(Calendar.YEAR));
System.out.println("Month = " + (cal.get(Calendar.MONTH) + 1));
System.out.println("Date = " + cal.get(Calendar.DATE));
// week
System.out.println("Week of month = " + cal.get(Calendar.WEEK_OF_MONTH));
System.out.println("Week of year = " + cal.get(Calendar.WEEK_OF_YEAR));
// time information
System.out.println("\nTime Information..........");
System.out.println("Hour (24 hour format) : " + cal.get(Calendar.HOUR_OF_DAY));
System.out.println("Hour (12 hour format) : " + cal.get(Calendar.HOUR));
System.out.println("Minute : " + cal.get(Calendar.MINUTE));
System.out.println("Second : " + cal.get(Calendar.SECOND));
System.out.println("Millisecond : " + cal.get(Calendar.MILLISECOND));
}
}输出结果
Mon Nov 19 14:28:46 UTC 2018 Date Information.......... Year = 2018 Month = 11 Date = 19 Week of month = 4 Week of year = 47 Time Information.......... Hour (24 hour format) : 14 Hour (12 hour format) : 2 Minute : 28 Second : 46 Millisecond : 464
