In Java, if you want to convert a LocalDateTime to an array of strings, you can format the LocalDateTime into a string representation and then store it in an array. Here's a simple example demonstrating how to do this:
|
|
|
|
java
|
|
Code kopieren
|
|
import java.time.LocalDateTime;
|
|
import java.time.format.DateTimeFormatter;
|
|
|
|
public class LocalDateTimeToStringArray {
|
|
public static void main(String[] args) {
|
|
// Create a LocalDateTime instance
|
|
LocalDateTime dateTime = LocalDateTime.now();
|
|
|
|
// Define the desired format
|
|
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
|
|
|
|
// Convert LocalDateTime to a formatted string
|
|
String formattedDateTime = dateTime.format(formatter);
|
|
|
|
// Create an array of strings and store the formatted LocalDateTime
|
|
String[] dateTimeArray = new String[1]; // Adjust the size based on your needs
|
|
dateTimeArray[0] = formattedDateTime;
|
|
|
|
// Print the array
|
|
for (String dt : dateTimeArray) {
|
|
System.out.println(dt);
|
|
}
|
|
}
|
|
}
|
|
Explanation:
|
|
LocalDateTime Creation: We create a LocalDateTime instance using LocalDateTime.now() to get the current date and time.
|
|
|
|
Formatter: We define a DateTimeFormatter with the desired format (e.g., "yyyy-MM-dd HH:mm
|
|
").
|
|
|
|
Formatting: We format the LocalDateTime into a string using the format method.
|
|
|
|
Array Creation: We create a string array and store the formatted date-time string in it.
|
|
|
|
Printing: Finally, we print the contents of the array.
|
|
|
|
Customization:
|
|
If you want to store multiple LocalDateTime values, you can create a larger array or use a collection like ArrayList<String> for dynamic sizing.
|
|
You can change the date format by modifying the pattern passed to DateTimeFormatter. |
