how can you write one java method that prints out the contents of any type of array with out knowing what type of array it is? for example, it could be an int[], an object[], a boolean[] and so on. What parameter do you give the method?

I've searched through a few of the "master the vi editor" sites but can't seem to find out how to use the tabbed functionality like I want to. Note: I'm not referring to the tab button or indenting, but the actual tabs for opening multiple files within a single vi command prompt.

Anyone know if there is a way to execute a program from a batch file and then continue executing the batch file?

I tried executing the program from a separate batch file and using "Call" to call that batch file, but the batch job just waits for this program to be closed before continuing.

I need the program to execute and remain running while the batch file continues...
