Java ZoneOffsetTransition isGap()用法及代碼示例

java.time.zone.ZoneOffsetTransition類的isGap()方法用於檢查此區域偏移集轉換所代表的本地時間是否存在任何間隙。

用法:

public boolean isGap()

參數：此方法不接受任何參數。

返回值：如果轉換之間存在間隙，則此方法返回true，否則返回false。

下麵是說明isGap()方法的示例：

範例1：

// Java program to demonstrate 
// isGap() 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, 59, 0); 
  
        // creating and initializing 
        // the object of ZoneOffset 
        ZoneOffset off1 
            = ZoneOffset.ofHoursMinutes(0, 8); 
  
        // creating and initializing 
        // the object of ZoneOffset 
        ZoneOffset off2 
            = ZoneOffset.ofTotalSeconds(9); 
  
        // creating and initializing 
        // ZoneOffsetTransition Object 
        ZoneOffsetTransition zonetrans1 
            = ZoneOffsetTransition.of( 
                loc, off1, off2); 
  
        // comparing both object using 
        // equals() method 
        boolean status = zonetrans1.isGap(); 
  
        // display the result 
        if (status) 
            System.out.println("there is a gap"); 
        else
            System.out.println("no gap found"); 
    } 
}

輸出：

no gap found

範例2：

// Java program to demonstrate 
// isGap() 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, 59, 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); 
  
        // comparing both object using 
        // equals() method 
        boolean status = zonetrans1.isGap(); 
  
        // display the result 
        if (status) 
            System.out.println("there is a gap"); 
        else
            System.out.println("no gap found"); 
    } 
}

輸出：

there is a gap
