In LocalDateTime class, there are two types of parse() method depending upon the parameters passed to it.
parse(CharSequence text)
parse() method of a LocalDateTime class used to get an instance of LocalDateTime from a string such as ‘2018-10-23T17:19:33’ passed as parameter.The string must have a valid date-time and is parsed using DateTimeFormatter.ISO_LOCAL_DATE_TIME. Syntax:
public static LocalDateTime parse(CharSequence text)
Parameters: This method accepts only one parameter text which is the text to parse in LocalDateTime. It should not be null. Return value: This method returns LocalDateTime which is the parsed local date-time. Exception: This method throws DateTimeParseException if the text cannot be parsed. Below programs illustrate the parse() method: Program 1:
Java
// Java program to demonstrate// LocalDateTime.parse() methodimport java.time.*;public class GFG { public static void main(String[] args) { // create an LocalDateTime object LocalDateTime lt = LocalDateTime .parse("2018-12-30T19:34:50.63"); // print result System.out.println("LocalDateTime : " + lt); }} |
LocalDateTime : 2018-12-30T19:34:50.630
parse(CharSequence text, DateTimeFormatter formatter)
parse() method of a LocalDateTime class used to get an instance of LocalDateTime from a string such as ‘2018-10-23T17:19:33’ passed as parameter using a specific formatter.The date-time is parsed using a specific formatter. Syntax:
public static LocalDateTime parse(CharSequence text,
DateTimeFormatter formatter)
Parameters: This method accepts two parameters text which is the text to parse and formatter which is the formatter to use. Return value: This method returns LocalDateTime which is the parsed local date-time. Exception: This method throws DateTimeParseException if the text cannot be parsed. Below programs illustrate the parse() method: Program 1:
Java
// Java program to demonstrate// LocalDateTime.parse() methodimport java.time.*;import java.time.format.*;public class GFG { public static void main(String[] args) { // create a formatter DateTimeFormatter formatter = DateTimeFormatter.ISO_LOCAL_DATE_TIME; // create an LocalDateTime object and LocalDateTime lt = LocalDateTime .parse("2018-12-30T19:34:50.63", formatter); // print result System.out.println("LocalDateTime : " + lt); }} |
LocalDateTime : 2018-12-30T19:34:50.630
