Could anyone explain what the feature of invoke, why do we need
invoke?
Thanks in advance.

You have stumbled on one of the most subtle features of Java called
reflection. Basically it allows you to call methods at run time that
were not written at compile time, and further whose structure too was
unknown, e.g. the names of the methods and the types of the
parameters.

You create call lists of parameters on the fly and invoke methods.
You can probe to find out what methods are available and what parms
they want.

see http://mindprod.com/jgloss/reflection.html

It is a tool to allow java code to use arbitrary class files handed to
it at run time.

You can usually get what you want without resorting to reflection
using dynamic loading.
