Java YearMonth isBefore()用法及代码示例

Java中Year类的isBefore()方法用于检查当前的YearMonth对象是否在指定为该方法的参数YearMonth之前。

用法：

public boolean isBefore(Year otherYearMonth)

参数：它接受单个参数otherYearMonth，它将与当前YearMonth对象进行比较。

返回值：如果此YearMonth对象的值在指定为方法参数的YearMonth对象的值之前，则返回布尔True值，否则返回False。

以下程序说明了Java中的YearMonth.isBefore()方法：

示例1:：

// Program to illustrate the isBefore() method 
  
import java.util.*; 
import java.time.*; 
  
public class GfG { 
    public static void main(String[] args) 
    { 
        // Create first Year object 
        YearMonth yearMonth1 
            = YearMonth.of(2018, 3); 
  
        // Create second Year object 
        YearMonth yearMonth2 
            = YearMonth.of(1997, 4); 
  
        // Check if this year-month object's value is 
        // before the specified Year-month or not 
        System.out.println(yearMonth1 
                               .isBefore(yearMonth2)); 
    } 
}

输出：

false

示例2:：

// Program to illustrate the isBefore() method 
  
import java.util.*; 
import java.time.*; 
  
public class GfG { 
    public static void main(String[] args) 
    { 
        // Create first Year object 
        YearMonth yearMonth1 
            = YearMonth.of(1997, 3); 
  
        // Create second Year object 
        YearMonth yearMonth2 
            = YearMonth.of(2018, 4); 
  
        // Check if this year-month object's value is 
        // before the specified Year-month or not 
        System.out.println(yearMonth1 
                               .isBefore(yearMonth2)); 
    } 
}

输出：

true
