2. Java format LocalDateTime to yyyy/MM/dd HH:mm:ss
3. Java format LocalDateTime to dd/MM/yyyy HH:mm:ss
4. Java format LocalDateTime to dd-MM-yyyy HH:mm:ss

Java format LocalDateTime to yyyy-MM-dd HH:mm:ss

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

public class Main {

    public static void main(String[] args) {

        // yyyy-MM-dd HH:mm:ss
        LocalDateTime localDateTime = LocalDateTime.now();
        DateTimeFormatter formatterLocalDateTime = 
                DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
        String ldt1 = formatterLocalDateTime.format(localDateTime);

        // or shortly
        String ldt2 = LocalDateTime.now()
                .format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
        
        System.out.println(ldt1);
        System.out.println(ldt2);
