method-declaration

I've seen some code written this way: @interface AViewController(Private) I wanted to know if that (Private) means something when submitting to the App Store? What does it mean in general? It's a category called 'Private'. Have a look in the Categories and Extensions chapter of the Objective-C programming reference What it means is that it is an addition to the AViewControler class that has been named 'Private' for convenience. It could have been called anything or even left blank to create a class extension. You can create private methods in your own code that your app can call. This is

I have not seen the particular thing before today when working on variable length argument For e.g., There is a method named prepared statement with declaration such that 1. String prepareStatement(String... columnNames,String... values) //String... columnNames(Eclipse shows error saying The variable argument type String of the method prepareStatement must be the last parameter) 2. Another method declaration String prepareStatement(int i,String... columnNames,String... values) //still the same result as above(The variable ...... parameter) Why does java not allow multiple variable length

In C#, if you want a method to have an indeterminate number of parameters, you can make the final parameter in the method signature a params so that the method parameter looks like an array but allows everyone using the method to pass as many parameters of that type as the caller wants. I'm fairly sure Java supports similar behaviour, but I cant find out how to do it. David Grant In Java it's called varargs , and the syntax looks like a regular parameter, but with an ellipsis ("...") after the type: public void foo(Object... bar) { for (Object baz : bar) { System.out.println(baz.toString()); }
