varags. If a method signature is method(Param param, String... x) it will take one Param type of object and any number of String objects.
There are couple if cool things about it:
It's nothing special. It's just sugared array. So,
method(MyObject... o)is same asmethod(MyObject[] o).Vararg has to be the last parameter in argument list.
There is this funny thing that bit me once.
method(MyObject... o)can be called asmethod()without any compilation error. Java will internally convert the no-arg call tomethod(new MyObject[0]). So, be aware of this.
