Java ChronoLocalDateTime toLocalTime()方法及示例

ChronoLocalDateTime 接口的 toLocalTime() 方法用于将这个ChronoLocalDateTime转换成LocalTime。该方法返回该ChronoLocalDateTime的LocalTime部分。

语法

default LocalTime toLocalTime()

参数： 该方法不接受任何参数。

返回值： 该方法返回 LocalTime ，即该ChronoLocalDateTime的LocalTime。

以下程序说明了toLocalTime()方法。

程序1 :

// Java program to demonstrate
// ChronoLocalDateTime.toLocalTime() method
  
import java.time.*;
import java.time.chrono.*;
  
public class GFG {
    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("LocalTime: "
                           + time.toLocalTime());
    }
}

输出:

ChronoLocalDateTime: 2019-12-31T19:15:30
LocalTime: 19:15:30

程序2

// Java program to demonstrate
// ChronoLocalDateTime.toLocalTime() 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("LocalTime: "
                           + time.toLocalTime());
    }
}

输出:

ChronoLocalDateTime: 2018-10-25T23:12:31.123
LocalTime: 23:12:31.123
