Java中的 Period ofWeeks() 方法及示例

Period 类的ofWeeks()方法用于从给定的周数中获取周期作为参数。此参数以整数形式接受。此方法返回具有给定周数的 Period。

句法：

public static Period ofWeeks(int numberOfWeeks)

参数：此方法接受单个参数numberOfWeeks ，它是要解析为 Period 对象的周数。

返回：此函数返回周期，它是使用给定周数解析的 Period 对象。

下面是 Period.ofWeeks() 方法的实现：

示例 1：

// Java code to demonstrate ofWeeks() method
  
import java.time.Period;
  
class GFG {
    public static void main(String[] args)
    {
  
        // Get the number of Weeks
        int numberOfWeeks = 5;
  
        // Parse the numberOfWeeks into Period
        // using ofWeeks() method
        Period p = Period.ofWeeks(numberOfWeeks);
  
        System.out.println(p.getYears() + " Years\n"
                           + p.getMonths() + " Months\n"
                           + p.getDays() + " Days");
    }
}

输出：

0 Years
0 Months
35 Days

示例 2：

// Java code to demonstrate ofWeeks() method
  
import java.time.Period;
  
class GFG {
    public static void main(String[] args)
    {
  
        // Get the number of Weeks
        int numberOfWeeks = -5;
  
        // Parse the numberOfWeeks into Period
        // using ofWeeks() method
        Period p = Period.ofWeeks(numberOfWeeks);
  
        System.out.println(p.getYears() + " Years\n"
                           + p.getMonths() + " Months\n"
                           + p.getDays() + " Days");
    }
}

输出：

0 Years
0 Months
-35 Days
