Java Data Type - 如何格式化日期为"23/06/2015"

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

public class Main {

  public static void main(String[] args) {
    System.out.println(toString(LocalDate.now()));
  }

  public static String toString(LocalDate date) {
      DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd/MM/yyyy");
      return date.format(formatter);
  }
}
