Java : How to convert String to Date?

 Introduction In this post, we will learn how to convert Java String to Date  Example: import java.util.Date; public class DateConversion { public static void main(String[] args) {      SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");      try { Date date = sdf.parse("19-09-2020"); System.out.println(date);      } catch (Exception ex) { ex.printStackTrace();      } } } In Java 8 and onward versions, we can use the LocalDate and DateTimeFormatter class to convert a String to a LocalDate object. We will use the parse method of the LocalDate class to perform this conversion Example (using Java 8+ versions) import java.time.LocalDate; import java.time.format.DateTimeFormatter; public class DateConversion { public static void main(String[] args) { DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd-MM-yyyy"); try { LocalDate date = LocalDate.parse("19-09-2020",formatter); System.out.println(da

Java : How to convert java.util.Date to java.sql.Date?
