About the Java method in object ... the meaning of the args parameter

When I read the volley source code from Google, I suddenly saw a way to do that, such as:V (String format, Object ... args)

do not understand what meaning, wondering why to write like this, with object[] args is a meaning? Why use three points instead? Later, this is the JDK1.5 new syntax, new features, dynamic Parameters , or variable parameter meaning.


Example:
There is a method v, which calls the v method
v (How many parameters are written in the line);

Like what:

V (1, "s"); V ("s"); V ("s");


When using this parameter inside a method, there is no difference from object[] args.

However, they are different when called.

void V (Object ... objs) {}v (obj1, Obj2, obj3);
