日曆API來顯示日期單獨

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()); 
      } 
     } 
    }

上述碼產生以下輸出 Date_Of_Joining java.util.GregorianCalendar中[時間= 1291275522078，areFieldsSet =真，areAllFieldsSet =真，寬大=真，區= sun.util。 calendar.ZoneInfo [ID = 「亞洲/加爾各答」，偏移= 19800000，dstSavings = 0，useDaylight =假，過渡= 6，lastRule =空]，Firstdayofweek可= 1，minimalDaysInFirstWeek = 1，ERA = 1，YEAR = 2010，MONTH = 11，WEEK_OF_YEAR = 49，WEEK_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]日曆API來顯示日期單獨

我只需要單獨打印日期。我應該如何更改代碼？

嗯，我個人會使用Joda Time（及其LocalDate類，如果你真的只是想保持日期），而不是java.util.Calendar，但如果你做想使用Calendar，你需要一個SimpleDateFormat。

java.util.Calendar中的示例：

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())); 
    } 
}

喬達時間樣本：

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)); 
    } 
}
