The isValidOffset() method of java.time.zone.ZoneOffsetTransition class is used to check if the particular zone offset is valid or not during the transition.
Syntax:
public boolean isValidOffset(ZoneOffset offset)
Parameter: this method used to take type of zone offset object as a parameter.
Return Value: This method returns true if the particular zone offset is valid or not during the transition otherwise false.
Below are the examples to illustrate the isValidOffset() method:
Example 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" ); } } |
zoneoffset is invalid
Example 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" ); } } |
zoneoffset is valid
zoneoffset is valid
