Convert LocalDateTime to String in Java

In Java, you can use the DateTimeFormatter class to convert a LocalDateTime object into a string. Here is an example code:

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

public class Main {
    public static void main(String[] args) {
        LocalDateTime now = LocalDateTime.now();
        
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
        String formattedDateTime = now.format(formatter);
        
        System.out.println("Formatted LocalDateTime: " + formattedDateTime);
    }
}

In the code above, we begin by creating a LocalDateTime object that represents the current date and time. Then, we use the DateTimeFormatter class to create a formatting template. Finally, we call the format method of the LocalDateTime object to convert it into a string and print it out.
