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

jasonmp85 is right about passing a different array to String.format. The size of an array can't be changed once constructed, so you'd have to pass a new array instead of modifying the existing one.

Object newArgs = new Object[args.length+1];
System.arraycopy(args, 0, newArgs, 1, args.length);
newArgs[0] = extraVar; 
String.format(format, extraVar, args);
