Java GregorianCalendar getMinimum()用法及代码示例

java.util.GregorianCalendar.getMinimum()方法是Java中的内置函数，它返回作为参数传递给该函数的特定日历字段的最小值。对于任何可能的时间值，它也是get()方法返回的最小值，同时考虑getFirstDayOfWeek()，getMinimalDaysInFirstWeek()，getGregorianChange()和getTimeZone()方法的当前值。

用法:

public int getMinimum(int calendarfield)

参数：该函数接受一个整数类型的强制性参数calendarfield，该函数的该GregorianCalender实例的最小值将返回。

返回值：
此方法为此GregorianCalender实例返回指定日历字段的最小值。

例子：

Input : DAY_OF_MONTH
Output : 1

Input : WEEK_OF_MONTH
Output : 0

以下程序说明了java.util.GregorianCalendar.getMinimum()函数的用法：

示例1:

// Java Program to illustrate getMinimum() function  
// GregorianCalender 
  
import java.io.*; 
import java.util.*; 
  
class GFG { 
     public static void main(String[] args) { 
      
      // Create a new calendar 
      GregorianCalendar cal = (GregorianCalendar)  
                        GregorianCalendar.getInstance(); 
  
      // Display the current date and time 
      System.out.println("Current Date and Time : "
                                    + cal.getTime()); 
  
      // Display minimum for WEEK_OF_MONTH 
      int minm = cal.getMinimum(GregorianCalendar.WEEK_OF_MONTH); 
      System.out.println("Minimum for WEEK_OF_MONTH field :"
                                                   + minm); 
  
      // Display minimum for DAY_OF_MONTH 
      minm = cal.getMinimum(GregorianCalendar.DAY_OF_MONTH); 
      System.out.println("Minimum for DAY_OF_MONTH field:"
                                                  + minm); 
   } 
}

输出：

Current Date and Time : Fri Jul 27 11:40:24 UTC 2018
Minimum for WEEK_OF_MONTH field :0
Minimum for DAY_OF_MONTH field:1

示例2:

// Java Program to illustrate getMinimum() function  
// GregorianCalender 
  
import java.io.*; 
import java.util.*; 
  
class GFG { 
     public static void main(String[] args) { 
      
      // Create a new calendar 
      GregorianCalendar cal = (GregorianCalendar)  
                        GregorianCalendar.getInstance(); 
  
      // Display the current date and time 
      System.out.println("Current Date and Time : "
                                         + cal.getTime()); 
  
      // Display minimum for YEAR 
      int minm = cal.getMinimum(GregorianCalendar.YEAR); 
      System.out.println("Minimum for YEAR field :"
                                          + minm); 
  
      // Display minimum for HOUR_OF_DAY 
      minm = cal.getMinimum(GregorianCalendar.HOUR_OF_DAY); 
      System.out.println("Minimum for HOUR_OF_DAY field :"
                                                  + minm); 
   } 
}

输出：

Current Date and Time : Fri Jul 27 11:40:28 UTC 2018
Minimum for YEAR field :1
Minimum for HOUR_OF_DAY field :0
