Method:

public String format(DateTimeFormatter formatter)

Returns the formatted string as specified by the provided DateTimeFormatter.

This method is defined as "default" method in ChronoLocalDate interface.


Examples:


package com.logicbig.example.localdate;

import java.time.LocalDate;
import java.time.Month;
import java.time.format.DateTimeFormatter;

public class FormatExample {
    public static void main (String[] args) {
        LocalDate localDate = LocalDate.of(1990, Month.MAY, 20);

        String s = localDate.format(DateTimeFormatter.BASIC_ISO_DATE);
        System.out.println("BASIC_ISO_DATE: " + s);

        s = localDate.format(DateTimeFormatter.ISO_DATE);
        System.out.println("ISO_DATE: " + s);

        s = localDate.format(DateTimeFormatter.ISO_LOCAL_DATE);
        System.out.println("ISO_LOCAL_DATE: " + s);

        s = localDate.format(DateTimeFormatter.ISO_ORDINAL_DATE);
        System.out.println("ISO_ORDINAL_DATE: " + s);

        s = localDate.format(DateTimeFormatter.ISO_WEEK_DATE);
        System.out.println("ISO_WEEK_DATE: " + s);
    }
}

Output

BASIC_ISO_DATE: 19900520
ISO_DATE: 1990-05-20
ISO_LOCAL_DATE: 1990-05-20
ISO_ORDINAL_DATE: 1990-140
ISO_WEEK_DATE: 1990-W20-7
