Java uses the Apache class library for time formatting
The Apache Commons Lang Library provides a time formatting class library. This class library provides some tool classes and methods that can be used to process and format dates and times.
The Maven coordinates of the dependent class library are:
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.12.0</version>
</dependency>
The following is a complete example of using Apache Commons Lang Library for time formatting, which is used to convert the current time to the specified format and output it to the console:
import org.apache.commons.lang3.time.DateFormatUtils;
import java.util.Date;
public class TimeFormattingExample {
public static void main(String[] args) {
Date currentDate = new Date();
String formattedDate = DateFormatUtils.format(currentDate, "yyyy-MM-dd HH:mm:ss");
System.out.println("Formatted Date: " + formattedDate);
}
}
In the above example, we first imported the 'org. apache. commons. lang3. time. DateFormatUtils' class and the' java. util. Date 'class. Then, we created a 'Date' object called 'currentDate', which contains the current date and time. Next, we use the 'DateFormatUtils. format()' method to convert the 'currentDate' object into a string in the specified format and store it in the 'formatedDate' variable. Finally, we print the formatted date string to the console.
Summary: The Apache Commons Lang Library in the Apache class library provides easy-to-use tool methods for easily formatting dates and times. Using this library, we can convert the date object into a specified formatted string. In this way, we can easily process and display dates and times in Java applications.
