java.time.ZoneOffset Class in Java

A time-zone offset is that the amount of your time that a time-zone differs from Greenwich/UTC. This is often usually a hard and fast number of hours and minutes. From the time package of java, ZoneOffset class is employed to represent the fixed zone offset from UTC zone and inherits the ZoneId class and implements the Comparable interface.

public final class ZoneOffset extends ZoneId    

implements TemporalAccessor, TemporalAdjuster, Comparable<ZoneOffset>, Serializable  

ZoneOffset class has three fields:

• MAX: It is the maximum supported zone offsets.
• MIN: It is the minimum supported zone offsets.
• UTC: It is the time zone offset constant for UTC.

Method of ZoneOffset class

1. ofHoursMinutes() Method:

syntax:

public static ZoneOffset ofHoursMinutes(int Hours, int Minutes)

This method is used to obtain an instance of ZoneOffset using an offset in hours and minutes.

// Example of ofHoursMinutes() Method
import java.time.ZoneOffset;  
public class GFG {  
  public static void main(String[] args) {  
    ZoneOffset zone = ZoneOffset.ofHoursMinutes(7,15);  
    System.out.println(zone);  
  }  
}

2. ofHours() Method

syntax:

public static ZoneOffset ofHours(int hours)

Obtains an instance of ZoneOffset using an offset in hours.

//Example of ofHours() Method
import java.time.*; 
import java.time.ZoneOffset;  
public class GFG {  
  public static void main(String[] args) {  
    ZoneOffset zone = ZoneOffset.ofHours(4);  
    System.out.println(zone);  
  }  
}
