In Java, dates can be represented using the Date class, which is a part of the java.util package. Here are some examples of how to use the Date class in Java 20:
1. Creating a Date object:
Date currentDate = new Date(); // creates a new Date object with the current date and time
2. Formatting a date:
SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy"); // create a date format
String formattedDate = dateFormat.format(currentDate); // format the current date in the desired format
System.out.println("Formatted Date: " + formattedDate); // print the formatted date
3. Parsing a date string:
String dateStr = "01/01/2020"; // create a date string
SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy"); // create a date format to match the string format
Date parsedDate = dateFormat.parse(dateStr); // parse the date string using the date format
System.out.println("Parsed Date: " + parsedDate); // print the parsed date
4. Comparing dates:
Date earlierDate = new Date(119, 0, 1); // create a date for Jan 1, 2019
Date laterDate = new Date(); // create a date object for the current date and time
if (earlierDate.compareTo(laterDate) < 0) {
System.out.println(earlierDate + " is earlier than " + laterDate);
} else if (earlierDate.compareTo(laterDate) > 0) {
System.out.println(earlierDate + " is later than " + laterDate);
} else {
System.out.println(earlierDate + " and " + laterDate + " are equal");
}
These are just a few examples of how to use the
Date class in Java. There are many more ways to work with dates, such as adding and subtracting time, managing time zones, and more. It's important to be familiar with the Date class and its methods if you want to work with dates in Java.
