Java YearMonth equals()用法及代碼示例

Java中Yearyearth類的equals()方法用於比較兩個YearMonth對象。它將這個YearMonth對象與作為參數傳遞給它的YearMonth對象進行比較，並檢查兩個YearMonth實例是否相等。

用法：

public boolean equals(Object otherYearMonth)

參數：此方法接受單個參數otherYearMonth，該參數是與此YearMonth進行比較的另一個YearMonth實例。

返回值：如果Yearyear等於otherYearMonth，則返回true，否則返回False。

以下程序說明了Java中YearMonth的equals()方法：
示例1:：

// Program to illustrate the equals() method 
  
import java.util.*; 
import java.time.*; 
  
public class GfG { 
    public static void main(String[] args) 
    { 
  
        // Creates first YearMonth object 
        YearMonth firstYearMonth = YearMonth.of(2017, 8); 
  
        // Creates second YearMonth object 
        YearMonth secondYearMonth = YearMonth.of(2016, 11); 
  
        // check if the two YearMonth instances are equal 
        System.out.println(firstYearMonth.equals(secondYearMonth)); 
    } 
}

輸出：

false

示例2:：

// Program to illustrate the equals() method 
  
import java.util.*; 
import java.time.*; 
  
public class GfG { 
    public static void main(String[] args) 
    { 
        // Creates first YearMonth object 
        YearMonth firstYearMonth = YearMonth.of(2017, 8); 
  
        // Creates second YearMonth object 
        YearMonth secondYearMonth = YearMonth.of(2017, 8); 
  
        // check if the two YearMonth instances are equal 
        System.out.println(firstYearMonth.equals(secondYearMonth)); 
    } 
}

輸出：

true
