ZoneOffsetTransition 是 Java 中的一个有效的 Offset()方法，示例
原文:https://www . geeksforgeeks . org/zoneoffsettransition-is valid offset-method-in-Java-with-example/
Java . time . zone . zoneoffset transition类的 isValidOffset() 方法用于检查在转换过程中特定的区域偏移是否有效。
语法:
public boolean isValidOffset(ZoneOffset offset)
参数:该方法用于将区域偏移对象的类型作为参数。
返回值:如果在转换期间特定区域偏移有效或无效，则该方法返回真，否则返回假。
以下是说明 isValidOffset() 方法的示例:
例 1:
// Java program to demonstrate
// isValidOffset() 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
// isValidOffset() method
boolean status
= zonetrans1
.isValidOffset(
ZoneOffset
.ofTotalSeconds(24));
// display the result
if (status)
System.out.println("zoneoffset is valid");
else
System.out.println("zoneoffset is invalid");
}
}
输出:
zoneoffset is invalid
例 2:
// Java program to demonstrate
// isValidOffset() 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(12);
// creating and initializing
// ZoneOffsetTransition Object
ZoneOffsetTransition zonetrans1
= ZoneOffsetTransition.of(
loc, off1, off2);
// comparing both object using
// isValidOffset() method
boolean status
= zonetrans1.isValidOffset(off1);
// display the result
if (status)
System.out.println("zoneoffset is valid");
else
System.out.println("zoneoffset is invalid");
}
}
输出:
zoneoffset is valid
输出:
zoneoffset is valid
