    public static void main(String[] args) 
    { 
  
        // create ChronoLocalDateTime object 
        ChronoLocalDateTime time 
            = LocalDateTime 
                  .parse("2019-12-31T19:15:30"); 
  
        // print ChronoLocalDateTime 
        System.out.println("ChronoLocalDateTime: "
                           + time); 
  
        // print result 
        System.out.println("String: "
                           + time.toString()); 
    } 
}

輸出：

ChronoLocalDateTime: 2019-12-31T19:15:30
String: 2019-12-31T19:15:30

示例2:

// Java program to demonstrate 
// ChronoLocalDateTime.toString() method 
  
import java.time.*; 
import java.time.chrono.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create ChronoLocalDateTime object 
        ChronoLocalDateTime time 
            = LocalDateTime.parse( 
                "2018-10-25T23:12:31.123"); 
  
        // print ChronoLocalDateTime 
        System.out.println("ChronoLocalDateTime: "
                           + time); 
  
        // print result 
        System.out.println("String: "
                           + time.toString()); 
    }
