A simple format for Java data The need to obtain the current system time is often used in the programming process, and may be used to detect system performance or for other considerations.Normally we need to format the current system time, and the process is rather annoying, but Java has a class that helps us solve the problem simply. Java.text.DateFormat class is very convenient for us to deal with the format of the time DateFormat is an abstract cl

And our

Then he seals monkeys and adds them to his team, this is "open", on the other hand This practice avoids monkeys from damaging the order of heaven, which is "closed". 3. Application of simple factory mode in Java A typical example is the DateFormat class that we usually use to format dates. Read a piece of code: import java.text.DateFormat;import java.
