Java 中的 ZoneOffsetTransition getOffsetBefore()方法，示例
原文:https://www . geeksforgeeks . org/zoneoffsettransition-getoffsetbefore-method-in-Java-with-example/
Java . time . zoneoffsettransition类的 getOffsetBefore() 方法用于获取作为参数传递的第一个区域偏移对象的偏移值。
语法:
public ZoneOffset getOffsetBefore()
参数:此方法不接受任何参数。
返回值:该方法返回作为参数传递的第一个区域偏移对象的偏移值。
下面是举例说明 getOffsetBefore() 方法的例子:
例 1:
// Java program to demonstrate
// getOffsetBefore() 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);
// getting the offset before value
// by using getOffsetBefore() method
ZoneOffset off
= zonetrans1.getOffsetBefore();
// display the result
System.out.println(
"Zoneoffset before transition : "
+ off);
}
}
输出:
Zoneoffset before transition : +00:00:08
例 2:
// Java program to demonstrate
// getOffsetBefore() 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(12);
// creating and initializing
// the object of ZoneOffset
ZoneOffset off2
= ZoneOffset.ofTotalSeconds(8);
// creating and initializing
// ZoneOffsetTransition Object
ZoneOffsetTransition zonetrans1
= ZoneOffsetTransition.of(
loc, off1, off2);
// getting the offset before value
// by using getOffsetBefore() method
ZoneOffset off
= zonetrans1.getOffsetBefore();
// display the result
System.out.println(
"Zoneoffset before transition : "
+ off);
}
}
输出:
Zoneoffset before transition : +00:00:12
