要使用Calendar类,请导入以下程序包。
import java.util.Calendar;
使用Calendar类,创建一个对象。
Calendar calendar = Calendar.getInstance();
现在,创建一个包含日期名称的字符串数组。
String[] days = new String[] { "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" };
显示日期名称。
days[calendar.get(Calendar.DAY_OF_WEEK) - 1]
以下是最后一个示例。
import java.util.Calendar; public class Demo { public static void main(String[] args) { Calendar calendar = Calendar.getInstance(); System.out.println("Day: " + (calendar.get(Calendar.DATE))); System.out.println("Month: " + (calendar.get(Calendar.MONTH) + 1)); System.out.println("Year: " + (calendar.get(Calendar.YEAR))); String[] days = new String[] { "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" }; System.out.println("Current day = " + days[calendar.get(Calendar.DAY_OF_WEEK) - 1]); } }
输出结果
Day: 19 Month: 11 Year: 2018 Current day = Monday
