Can I pass an array as arguments to a method with variable arguments in Java?

Question

I\'d like to be able to create a function like:

class A {
  private String extraVar;
  public String myFormat(String format, Object ... args){
    return Str

It's ok to pass an array - in fact it amounts to the same thing

String.format("%s %s", "hello", "world!");

is the same as

String.format("%s %s", new Object[] { "hello", "world!"});

It's just syntactic sugar - the compiler converts the first one into the second, since the underlying method is expecting an array for the vararg parameter.
