Java中的 Calendar getGreatestMinimum() 方法及示例
Calendar 类中的getGreatestMinimum(int calndr_field )方法用于返回此 Calendar 实例的给定日历字段 (int calndr_field) 的最大最小值。
句法:
public abstract int getGreatestMinimum(int calndr_field)
参数:该方法采用一个参数calndr_field ,该参数引用要操作的日历字段。
返回值:该方法返回此日历字段的最低最大值。
下面的程序说明了 Calendar 类的 getGreatestMinimum() 方法的工作原理:
示例 1:
// Java code to illustrate
// getGreatestMinimum() method
import java.util.*;
public class Java_Calendar_Demo {
public static void main(String[] args)
{
// Creating a calendar
Calendar calndr = new GregorianCalendar(2018, 6, 10);
// Calculating the highest min value
int rslt = calndr.getGreatestMinimum(Calendar.YEAR);
// Displaying the highest min value
System.out.println("The minimum year is: " + rslt);
}
}
输出:
The minimum year is: 1
示例 2:
// Java code to illustrate
// getGreatestMinimum() method
import java.util.*;
public class Java_Calendar_Demo {
public static void main(String[] args)
{
// Creating a calendar
Calendar calndr = Calendar.getInstance();
// Calculating the highest min value
int rslt = calndr.getGreatestMinimum(Calendar.MONTH);
// Displaying the highest min value
System.out.println("The minimum month is: " + rslt);
}
}
输出:
The minimum month is: 0
