SimpleDateFormat is sub flat of DateFormat in addition to render format() in addition to parse() method to convert Date to in addition to from String inward Java. Worth noting is that SimpleDateFormat is non thread-safe in addition to should non live on shared alongside others. Avoid using static SimpleDateFormat inward Java classes. If y'all desire to part SimpleDateFormat or desire to larn far thread-safe, y'all tin purpose ThreadLocal variable inward Java to avoid sharing SimpleDateFormat amidst multiple threads. parse() method of SimpleDateFormat throws ParseException if String input is non a valid engagement or tin non live on parsed into mentioned format.

How to format Date inward Java

public class DateFormatExample {

    public static void main(String args[]) {
     
        // This is how to larn today's engagement inward Java
        Date today = new Date();
     
        //If y'all impress Date, y'all volition larn un formatted output
        System.out.println("Today is : " + today);
     
        //formatting engagement inward Java using SimpleDateFormat
        SimpleDateFormat DATE_FORMAT = new SimpleDateFormat("dd-MM-yyyy");
        String engagement = DATE_FORMAT.format(today);
        System.out.println("Today inward dd-MM-yyyy format : " + date);
     
        //Another Example of formatting Date inward Java using SimpleDateFormat
        DATE_FORMAT = new SimpleDateFormat("dd/MM/yy");
        engagement = DATE_FORMAT.format(today);
        System.out.println("Today inward dd/MM/yy designing : " + date);
     
        //formatting Date alongside fourth dimension information
        DATE_FORMAT = new SimpleDateFormat("dd-MM-yy:HH:mm:SS");
        engagement = DATE_FORMAT.format(today);
        System.out.println("Today inward dd-MM-yy:HH:mm:SS : " + date);
     
        //SimpleDateFormat illustration - Date alongside timezone information
        DATE_FORMAT = new SimpleDateFormat("dd-MM-yy:HH:mm:SS Z");
        engagement = DATE_FORMAT.format(today);
        System.out.println("Today inward dd-MM-yy:HH:mm:SSZ : " + date);
     
    }
 
}

Output:
Today is : Friday November 02 16:11:27 IST 2012
Today inward dd-MM-yyyy format : 02-11-2012
Today inward dd/MM/yy designing : 02/11/12
Today inward dd-MM-yy:HH:mm:SS : 02-11-12:16:11:316
Today inward dd-MM-yy:HH:mm:SSZ : 02-11-12:16:11:316 +0530

That's all on these SimpleDateFormat Example inward Java. We direct maintain seen How to format engagement alongside fourth dimension in addition to timezone information inward Java. Though using SimpleDateFormat is almost slow way to format Date inward Java but it too has its ain ready of problems. It's non thread-safe in addition to should live on used carefully. Avoid using DateFormat as static variable, don't part SimpleDateFormat betwixt multiple threads, resultant is unpredictable if it's shared amidst multiple threads.
