The java.util.GregorianCalendar.getTimeZone() method is an in-built method in Java which fetches the time zone and returns the TimeZone object associated with this calendar.

Syntax: 

public TimeZone getTimeZone()

Parameters: This method does not accept any parameter.
Return Values: This method returns a TimeZone object which denotes the time zone of this calendar.

Examples:  

Input : Mon Jul 23 19:45:33 UTC 2018
Output : Coordinated Universal Time

Input : Wed Oct 23 20:02:52 UTC 2019
        cal.setTimeZone(TimeZone.getTimeZone("CST"));
Output : Central Standard Time

Below programs illustrate the java.util.GregorianCalendar.getTimeZone() function in Java:

Program 1: 

Java




// Java Program to  illustrate
// GregorianCalendar.getTimeZone()
// function
 
import java.io.*;
import java.util.*;
 
class GFG {
     public static void main(String[] args) {
     
      // Create a new calendar
      GregorianCalendar cal = (GregorianCalendar)
                        GregorianCalendar.getInstance();
 
      //Display the current date and time
      System.out.println("Current Date and Time : "
                            + cal.getTime());
       
      /* Creating a Time Zone object and
         storing this TimeZone */
      TimeZone t = cal.getTimeZone();
 
      // Display the time zone
      System.out.println("Time Zone : " +
                        t.getDisplayName());
   }
}

Output: 

Current Date and Time : Wed Jul 25 11:25:16 UTC 2018
Time Zone : Coordinated Universal Time

 

Program 2: In this program, we use setTimeZone() to change the current time zone and then fetch the new time zone using getTimeZone() method.

Java




// Java Program to  illustrate
// GregorianCalendar.getTimeZone()
// function
 
import java.io.*;
import java.util.*;
 
class GFG {
     public static void main(String[] args) {
     
      // Create a new calendar
      GregorianCalendar cal = (GregorianCalendar)
                        GregorianCalendar.getInstance();
 
      // Display the current date and time
      System.out.println("Current Date and Time : "
                            + cal.getTime());
      // Changing the current time zone                    
      cal.setTimeZone(TimeZone.getTimeZone("CST"));
     
      /* Creating a Time Zone object and
         storing the TimeZone */
      TimeZone t = cal.getTimeZone();
       
      // Display the time zone
      System.out.println("Time Zone : " +
                        t.getDisplayName());
   }
}

Output: 

Current Date and Time : Wed Jul 25 11:25:22 UTC 2018
Time Zone : Central Standard Time
