TimeZone validation in Java

Question

I have a string, I need to check whether it is a standard time zone identifier or not. I am not sure which method I need to use.

String timeZoneToCheck = \"UTC\"         


        

Answer 1

it's simple just use ZoneId.of("Asia/Kolkata")

try {
    ZoneId.of("Asia/Kolkataa");
} catch (Exception e) {
    e.printStackTrace();
}

if your insert invalid time zone it will throw exception

**java.time.zone.ZoneRulesException: Unknown time-zone ID: Asia/Kolkataa**
