下面是说明localDateTime()方法的示例：

范例1：

// Java program to demonstrate 
// localDateTime() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*; 
import java.time.chrono.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
            // creating and initializing 
            // JapaneseDate Object 
            JapaneseDate hidate 
                = JapaneseDate.now(); 
  
            // getting JapaneseChronology 
            // used in JapaneseDate 
            JapaneseChronology crono 
                = hidate.getChronology(); 
  
            // creating and initializing 
            // TemporalAccessor object 
            ZonedDateTime zonedate 
                = ZonedDateTime.parse( 
                    "2018-10-25T23:12:31."
                    + "123+02:00[Europe/Paris]"); 
  
            // getting JapaneseDate for the 
            // given TemporalAccessor object 
            // by using localDateTime() method 
            ChronoLocalDateTime<JapaneseDate> date 
                = crono.localDateTime(zonedate); 
  
            // display the result 
            System.out.println("JapaneseDate is:"
                               + date); 
        } 
        catch (DateTimeException e) { 
            System.out.println( 
                "passed parameter can"
                + " not form a date"); 
            System.out.println( 
                "Exception thrown:" + e); 
        } 
    } 
}

输出：

JapaneseDate is:Japanese Heisei 30-10-25T23:12:31.123

范例2：

// Java program to demonstrate 
// localDateTime() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*; 
import java.time.chrono.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
            // creating and initializing 
            // JapaneseDate Object 
            JapaneseDate hidate 
                = JapaneseDate.now(); 
  
            // getting JapaneseChronology 
            // used in JapaneseDate 
            JapaneseChronology crono 
                = hidate.getChronology(); 
  
            // creating and initializing 
            // TemporalAccessor object 
            LocalDateTime localdate 
                = LocalDateTime 
                      .parse("2018-12-30T19:34:50.63"); 
  
            // getting JapaneseDate for the 
            // given TemporalAccessor object 
            // by using localDateTime() method 
            ChronoLocalDateTime<JapaneseDate> date 
                = crono.localDateTime(localdate); 
  
            // display the result 
            System.out.println("JapaneseDate is:"
                               + date); 
        } 
        catch (DateTimeException e) { 
            System.out.println("passed parameter can"
                               + " not form a date"); 
            System.out.println("Exception thrown:" + e); 
        } 
    } 
}

输出：

JapaneseDate is:Japanese Heisei 30-12-30T19:34:50.630
