Short solution:

xxxxxxxxxx
 
// solution 1
String strDate = "24/12/2019";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd/MM/yyyy");
LocalDate localDate = LocalDate.parse(strDate, formatter); // 2019-12-24

Below we have examples showing how we can convert string date in different formats to LocalDate. LocalDate class was introduced in Java 8.

1. Using DateTimeFormatter and LocalDate.parse()

Edit

xxxxxxxxxx
 
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
​
public class Example1 {
​
    public static void main(String[] args) {
        String strDate = "24/12/2019";
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd/MM/yyyy");
        LocalDate localDate = LocalDate.parse(strDate, formatter);
        System.out.println(localDate); // 2019-12-24
    }
}

2. Format - yyyy-mm-dd

Edit

String to LocalDate with date format yyyy-mm-dd - ISO_LOCAL_DATE

xxxxxxxxxx
 
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
​
public class LocalDateExample1_ISO_LOCAL_DATE {
​
    public static void main(String[] args) {
​
        DateTimeFormatter formatter = DateTimeFormatter.ISO_LOCAL_DATE;
        String date = "2019-10-12";
        LocalDate localDate = LocalDate.parse(date, formatter);
​
        System.out.println(date);
        System.out.println(localDate);
        System.out.println(formatter.format(localDate));
    }
}

Output:

xxxxxxxxxx
 
2019-10-12
2019-10-12
2019-10-12

3. Format - yyyymmdd

Edit

String to LocalDate with date format yyyymmdd - BASIC_ISO_DATE

xxxxxxxxxx
 
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
​
public class LocalDateExample2_BASIC_ISO_DATE {
​
    public static void main(String[] args) {
​
        DateTimeFormatter formatter = DateTimeFormatter.BASIC_ISO_DATE;
        String date = "20191012";
        LocalDate localDate = LocalDate.parse(date, formatter);
​
        System.out.println(localDate);
        System.out.println(formatter.format(localDate));
    }
}

Output:

xxxxxxxxxx
 
2019-10-12
20191012

4. Format - E, MMM dd yyyy

Edit

String to LocalDate with date format E, MMM dd yyyy

xxxxxxxxxx
 
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
​
public class LocalDateExample3 {
​
    public static void main(String[] args) {
​
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("E, MMM dd yyyy");
        String date = "Sat, Oct 12 2019";
        LocalDate localDate = LocalDate.parse(date, formatter);
​
        System.out.println(localDate);
        System.out.println(formatter.format(localDate));
    }
}

Output:

xxxxxxxxxx
 
2019-10-12
Sat, Oct 12 2019

5. Format - EEEE, MMM dd yyyy

Edit

String to LocalDate with date format EEEE, MMM dd yyyy

        LocalDate localDate = LocalDate.parse(date, formatter);
​
        System.out.println(localDate);
        System.out.println(formatter.format(localDate));
    }
}
