Java 日历 getMinimum()方法及示例

Calendar类中的 getMinimum(int calndr_field )方法用于返回这个Calendar实例的给定日历字段(int calndr_field)的最小值。

语法

public abstract int getMinimum(int calndr_field)

参数： 该方法需要一个参数calndr_field，指的是要操作的日历字段。

返回值： 该方法返回传递的日历字段的最小值。

下面的程序说明了日历类的getMinimum()方法的工作原理：

示例1 :

// Java code to illustrate
// getMinimum() method
  
import java.util.*;
  
public class Calendar_Demo {
    public static void main(String args[])
    {
  
        // Creating a calendar
        Calendar calndr
            = Calendar.getInstance();
  
        // Getting the required months
        System.out.println("Required days: "
                           + calndr.get(
                                 Calendar.DAY_OF_WEEK));
  
        // Getting the Minimum month
        int max_day
            = calndr.getMinimum(
                Calendar.DAY_OF_WEEK);
  
        // Displaying the results
        System.out.println("The Minimum"
                           + " days: "
                           + max_day);
    }
}

输出:

Required days: 3
The Minimum days: 1

例2 :

// Java code to illustrate
// getMinimum() method
  
import java.util.*;
  
public class Calendar_Demo {
    public static void main(String args[])
    {
  
        // Creating a calendar
        Calendar calndr
            = new GregorianCalendar(2018, 6, 10);
  
        // Getting the required months
        System.out.println("Required Months: "
                           + calndr.get(
                                 Calendar.MONTH));
  
        // Getting the Minimum month
        int max_month
            = calndr.getMinimum(Calendar.MONTH);
  
        // Displaying the results
        System.out.println("The"
                           + " Minimum months: "
                           + max_month);
    }
}

输出:

Required Months: 6
The Minimum months: 0
