日历api单独显示日期

    import java.util.Calendar;

    public class Employee {
        private Calendar doj; 
        public Employee(Calendar date) {
            // TODO Auto-generated constructor stub
            this.doj=date;
        }
        public Calendar getDoj() 
        { 
        return doj; 
        } 

    }



import java.util.ArrayList;
import java.util.Calendar;
import java.util.List;


public class TestEmployeeSort {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        List<Employee> coll = getEmployees();
        printList(coll);
    }
        public static List<Employee> getEmployees() 
        { 
            List<Employee> col = new ArrayList<Employee>();

            col.add(new Employee(Calendar.getInstance()));
            return col;
        } 
        private static void printList(List<Employee> list) { 
            System.out.println("Date_Of_Joining"); 

            for (int i = 0; i < list.size(); i++) { 
                Employee e = list.get(i); 
                System.out.println(e.getDoj()); 
            } 
        } 
    }

以上代码产生以下输出Date_Of_Joining java.util.GregorianCalendar [time = 1291275522078，areFieldsSet = true，areAllFieldsSet = true，lenient = true，zone = sun.util.calendar.ZoneInfo [id =“Asia / Calcutta”，offset = 19800000，dstSavings = 0，useDaylight =假，过渡= 6，lastRule =空]，Firstdayofweek可= 1，minimalDaysInFirstWeek = 1，ERA = 1，YEAR = 2010，月= 11，WEEK_OF_YEAR = 49，WE​​EK_OF_MONTH = 1，DAY_OF_MONTH = 2 ，DAY_OF_YEAR = 336，DAY_OF_WEEK = 5，DAY_OF_WEEK_IN_MONTH = 1，AM_PM = 1，HOUR = 1，HOUR_OF_DAY = 13，MINUTE = 8，SECOND = 42，微差= 78，ZONE_OFFSET = 19800000，DST_OFFSET = 0]

我只需要单独打印日期。 我应该如何更改代码？

那么我个人会使用乔达时间（和它的LocalDate类，如果你真的只想维护日期）而不是java.util.Calendar ，但如果你想使用Calendar ，你需要一个SimpleDateFormat 。

java.util.Calendar示例：

import java.util.*;
import java.text.*;

public class Test
{
    public static void main(String[] args)
    {
        Calendar calendar = Calendar.getInstance();
        SimpleDateFormat format = new SimpleDateFormat("dd/MM/yyyy");
        System.out.println(format.format(calendar.getTime()));
    }
}

乔达时间样本：

import org.joda.time.*;
import org.joda.time.format.*;

public class Test
{
    public static void main(String[] args)
    {
        LocalDate today = new LocalDate();
        // Alternatively, use DateTimeFormat.mediumDate etc
        DateTimeFormatter formatter = DateTimeFormat.forPattern("dd/MM/yyyy");
        System.out.println(formatter.print(today));
    }
}

使用java.text.DateFormat而不是裸露的Calendar 。

使用返回Date的Caledar.getTime（）。 然后使用SimpleDateFormat根据需要对其进行格式化。
