Java 中的 ZoneOffsetTransition isGap()方法,示例

原文:https://www . geeksforgeeks . org/zoneoffsettransition-isgap-method-in-Java-with-example/

Java . time . zone . OffsetTransition类的 isGap() 方法用于检查该区域 offset transition 所代表的本地时间是否有间隙。

语法:

public boolean isGap()

参数:该方法不接受任何参数。

返回值:如果过渡中有间隙,该方法返回真,否则返回假。

以下是说明 isGap() 方法的例子:

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");
    }
}

输出:

no gap found

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");
    }
}

输出:

there is a gap
