Week numbers in Java
To get the current ISO 8601 week number in Java, use the following code snippet:
import java.time.LocalDate;
import java.time.temporal.IsoFields;
int week = LocalDate.now().get(IsoFields.WEEK_OF_WEEK_BASED_YEAR);
* Ensure your system or application regional settings are set to follow ISO 8601 standards (weeks start on Monday) if the output varies.
