hi.
i have not been able to understand the var-args syntax and in what way should the var arg be the last of a method's argument.
could you explain with an example.
thanks

you can declare

public void static main(String... a){

}
thats means you can pass variable number of Strings each time you call main.
Is that clear.

like
java SampleProgram one two three
java SampleProgram write until you satisfy
 
It is sorta covered in the JavaRanch Style Guide.
