Java version:

java.util.Date class

Get Date object, new comes out

Call getTime() method of Date object to get timestamp (millisecond value)

java.text.SimpleDateFormat class

Get SimpleDateFormat object, new out, construction parameters: "y-MM-dd hh:mm:ss"

Call format() method of SimpleDateFormat object to get date of String type, parameter: Date object

For example:

Date date=new Date(); SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd hh:mm:ss"); System.out.println(format.format(date)); This is where the content of "Comparative analysis of PHP and Java date-time function examples" is introduced.
