Java YearMonth compareTo()用法及代碼示例


Java中Yearyearth類的compareTo()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。兩個YearMonth實例之間的比較首先是根據Year的值進行的,然後是對Month的比較。

用法

public int compareTo(YearMonth 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:根據同位格返回一個整數比較器值:

  • 如果Yearyear大於otherYearMonth,則返回1。
  • 如果Yearyear小於otherYearMonth,則返回-1。
  • 如果YearMonth等於otherYearMonth,則返回0。

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

// Program to illustrate the compareTo() 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); 
  
        // compare the two YearMonth instances 
        System.out.println(firstYearMonth.compareTo(secondYearMonth)); 
    } 
}
輸出:
1

示例2:

// Programt to illustrate the compareTo() method 
  
import java.util.*; 
import java.time.*; 
  
public class GfG { 
    public static void main(String[] args) 
    { 
  
        // Creates first YearMonth object 
        YearMonth firstYearMonth = YearMonth.of(2016, 11); 
  
        // Creates second YearMonth object 
        YearMonth secondYearMonth = YearMonth.of(2016, 11); 
  
        // compare the two YearMonth instances 
        System.out.println(firstYearMonth.compareTo(secondYearMonth)); 
    } 
}
輸出:
0
