Example 1: Convert String to Date using predefined formatters
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
public class TimeString {
public static void main(String[] args) {
// Format y-M-d or yyyy-MM-d
String string = "2017-07-25";
LocalDate date = LocalDate.parse(string, DateTimeFormatter.ISO_DATE);
System.out.println(date);
}
}
Output
2017-07-25
In the above program, we've used the predefined formatter ISO_DATE that takes date string in the format 2017-07-25 or 2017-07-25+05:45'.
The LocalDate's parse() function parses the given string using the given formatter. You can also remove the ISO_DATE formatter in the above example and replace the parse() method with:
LocalDate date = LocalDate.parse(string, DateTimeFormatter);
Example 2: Convert String to Date using pattern formatters
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
import java.util.Locale;
public class TimeString {
public static void main(String[] args) {
String string = "July 25, 2017";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("MMMM d, yyyy", Locale.ENGLISH);
LocalDate date = LocalDate.parse(string, formatter);
System.out.println(date);
}
}
Output
2017-07-25
In the above program, our date is in the format MMMM d, yyyy. So, we create a formatter of the given pattern. Check all DateTimeFormatter patterns, if you're interested.
Now, we can parse the date using LocalDate.parse() function and get the LocalDate object.
