In Java, the DateFormat class is an abstract class used for formatting dates and times. It provides methods for converting date objects into string representations and parsing string representations into date objects.<\/p>\n

The main steps to use the DateFormat class are as follows:<\/p>\n

    \n
  1. Create a DateFormat object, which can be used with its subclass SimpleDateFormat to specify the date format.<\/li>\n
  2. Create a date format by using the SimpleDateFormat class, with the pattern “yyyy-MM-dd HH:mm:ss”.<\/li>\n
  3. In the above example, the date format is “yyyy-MM-dd HH:mm:ss”, where:<\/li>\n
  4. yyyy: A four-digit year.<\/li>\n
  5. MM: Months in double digits<\/li>\n
  6. dd: Date in two digits<\/li>\n
  7. HH: Double-digit hour (in the 24-hour clock)<\/li>\n
  8. mm: minutes in two digits<\/li>\n
  9. ss: double-digit seconds<\/li>\n
  10. Format the date object as a string.<\/li>\n
  11. Create a new instance of Date to obtain the current date and time. Format the date using the specified date format and then print it out.<\/li>\n
  12. The examples above format the current date and time into a string, and print it out.<\/li>\n
  13. Parse the string into a date object.<\/li>\n
  14. Convert the string “2021-01-01 12:00:00” to a date format and print the parsed date.<\/li>\n
  15. The above example parses the string “2021-01-01 12:00:00” into a date object and prints it out.<\/li>\n<\/ol>\n

    It should be noted that the DateFormat class is not thread-safe, so it is recommended to avoid sharing DateFormat objects in a multi-threaded environment.<\/p>\n","protected":false},"excerpt":{"rendered":"
