Java ZoneOffsetTransition equals()用法及代碼示例

java.time.zone.ZoneOffsetTransition類的equals()方法用於在ZoneOffsetTransition類型的兩個對象之間進行比較。

用法:

public boolean equals(Object other)

參數：此方法將其他zoneoffsetTransition的對象作為參數。

返回值：如果兩個對象相等，則此方法返回true，否則返回false。

下麵是說明equals()方法的示例：

範例1：

// Java program to demonstrate 
// equals() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*; 
import java.time.chrono.*; 
import java.time.zone.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
  
        // creating and initializing 
        // the object of LocalDateTime 
        LocalDateTime loc 
            = LocalDateTime.of( 
                1999, 04, 25, 03, 
                24, 45, 0); 
  
        // creating and initializing 
        // the object of ZoneOffset 
        ZoneOffset off1 
            = ZoneOffset.ofTotalSeconds(8); 
  
        // creating and initializing 
        // the object of ZoneOffset 
        ZoneOffset off2 
            = ZoneOffset.ofTotalSeconds(12); 
  
        // creating and initializing 
        // ZoneOffsetTransition Object 
        ZoneOffsetTransition zonetrans1 
            = ZoneOffsetTransition.of( 
                loc, off1, off2); 
  
        // creating and initializing 
        // ZoneOffsetTransition Object 
        ZoneOffsetTransition zonetrans2 
            = ZoneOffsetTransition.of( 
                loc, off1, off2); 
  
        // comparing both object using 
        // equals() method 
        boolean status 
            = zonetrans1.equals(zonetrans2); 
  
        // display the result 
        if (status) 
            System.out.println( 
                "zonetrans1 is equal to zonetrans2"); 
        else
            System.out.println( 
                "zonetrans1 is not equal to zonetrans2"); 
    } 
}

輸出：

zonetrans1 is equal to zonetrans2

範例2：

// Java program to demonstrate 
// equals() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*;

    { 
  
        // creating and initializing

        LocalDateTime loc 
            = LocalDateTime.of( 
                1999, 04, 25, 
                03, 24, 45, 0); 
  
        // creating and initializing 
        // the object of ZoneOffset 
        ZoneOffset off1 
            = ZoneOffset.ofTotalSeconds(8); 
  
        // creating and initializing 
        // the object of ZoneOffset 
        ZoneOffset off2 
            = ZoneOffset.ofTotalSeconds(12); 
  
        // creating and initializing 
        // ZoneOffsetTransition Object 
        ZoneOffsetTransition zonetrans1 
            = ZoneOffsetTransition.of( 
                loc, off1, off2); 
  
        // creating and initializing 
        // ZoneOffsetTransition Object 
        ZoneOffsetTransition zonetrans2 
            = ZoneOffsetTransition 
                  .of(LocalDateTime.of( 
                          1999, 04, 25, 03, 
                          24, 48, 0), 
                      off1, off2); 
  
        // comparing both object using 
        // equals() method 
        boolean status 
            = zonetrans1.equals(zonetrans2); 
  
        // display the result 
        if (status) 
            System.out.println( 
                "zonetrans1 is equal to zonetrans2"); 
        else
            System.out.println( 
                "zonetrans1 is not equal to zonetrans2"); 
    } 
}

輸出：

zonetrans1 is not equal to zonetrans2
