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"); }} |
Output:
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"); }} |
Output:
zoneoffset is valid
Output:
zoneoffset is valid
