SimpleDateFormat outputFormat = new SimpleDateFormat("yyyy-MM-dd") SimpleDateFormat inputFormat = new SimpleDateFormat("dd-MM-yyyy") Here’s an example of how to create a SimpleDateFormat object: You’ll use this object to specify the input format and the output format. The first step in converting dates is to create a “SimpleDateFormat” object. Converting Dates from one Format to Another in Java Step 1 : Creating a SimpleDateFormat Object In this post, we’ll look at how to use the “SimpleDateFormat” class to convert dates from one format to another. It allows you to control the display and interpretation of date and time values by defining patterns that align with your desired format.In Java, you may need to convert dates from one format to another, whether it be for display purposes or to store the dates in a database. SimpleDateFormat provides a convenient way to format and parse dates in Java. If you plan to use SimpleDateFormat concurrently in a multi-threaded environment, you should either synchronize access to the SimpleDateFormat instance or consider using alternative thread-safe date formatting libraries like introduced in Java 8. It's worth noting that SimpleDateFormat is not thread-safe. It's important to handle this exception to gracefully manage invalid or unexpected date formats. ParseException is a checked exception that can be thrown when parsing a date string that doesn't match the specified pattern. When working with SimpleDateFormat, it's crucial to handle potential exceptions. For instance, if you want to display the date as "June 29, 2023," you can create a custom pattern like "MMMM dd, yyyy". You can create patterns that suit your specific requirements and match the desired date format. One of the strengths of SimpleDateFormat is its flexibility to define custom patterns. (stringDate6 + " : " + date6.format(nDate6)) (stringDate5 + " : " + date5.format(nDate5)) (stringDate4 + " : " + date4.format(nDate4)) (stringDate3 + " : " + date3.format(nDate3)) ![]() (stringDate2 + " : " + date2.format(nDate2)) (stringDate + " : " + date.format(nDate1)) String stringDate2 = "02-09-1995 23:37:50" ĭateFormat date = new SimpleDateFormat("dd/MM/yyyy") ĭateFormat date2 = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss") ĭateFormat date3 = new SimpleDateFormat("dd-MMM-yyyy") ĭateFormat date4 = new SimpleDateFormat("MM dd, yyyy") ĭateFormat date5 = new SimpleDateFormat("E, MMM dd yyyy") ĭateFormat date6 = new SimpleDateFormat("E, MMM dd yyyy HH:mm:ss") You specify a pattern that matches the structure of the date string you want to parse, and SimpleDateFormat converts it into a Date object. Parsing refers to the process of converting a date string into a Date object, which can be used for further manipulation or calculations. ![]() In addition to formatting, SimpleDateFormat also allows you to parse dates. "h" represents the hour in 12-hour format."H" represents the hour in 24-hour format.Here are some common pattern characters used in SimpleDateFormat: For example, the pattern "yyyy-MM-dd" represents a date in the format "year-month-day", such as "". The pattern consists of a combination of specific characters that represent different elements of a date, such as the year, month, day, hour, minute, and second. You can specify a pattern that defines how the date should be displayed. One of the key features of SimpleDateFormat is its ability to format dates. ![]() It provides a straightforward and flexible way to handle date and time values in various formats. ![]() The SimpleDateFormat class in Java, which belongs to the java.text package, is a powerful tool for formatting and parsing dates according to specified patterns.
