Java YearMonth isBefore()用法及代碼示例

Java中Year類的isBefore()方法用於檢查當前的YearMonth對象是否在指定為該方法的參數YearMonth之前。

用法：

public boolean isBefore(Year otherYearMonth)

參數：它接受單個參數otherYearMonth，它將與當前YearMonth對象進行比較。

返回值：如果此YearMonth對象的值在指定為方法參數的YearMonth對象的值之前，則返回布爾True值，否則返回False。

以下程序說明了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)); 
    } 
}

輸出：

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)); 
    } 
}
