The runtime system always executes the statements within the finally block regardless of what happens within the try block. So it's the perfect place to perform cleanup.

whichReturns() needs to be declared as static for this code to compile, i.e. public static String whichReturns()
Once that's done then the program outputs "2"

In main, WhichReturns.whichReturns() can only work if whichReturns() is declared static
