printDashed

Language/Type: Java recursion recursive programming
Author: Stuart Reges (on 2014/02/13)

Write a recursive method called printDashed that takes an integer as a parameter and that prints the integer with dashes in between the digits.

The table below shows sample calls and the output that should be produced: 

        Method call            Output       Method call             Output
        ------------------------------      ---------------------------------
        printDashed(-834)       -8-3-4      printDashed(6)          6
        printDashed(-17)        -1-7        printDashed(42)         4-2
        printDashed(-4)         -4          printDashed(983)        9-8-3
        printDashed(0)          0           printDashed(29348)      2-9-3-4-8

Notice that no dashes are printed for positive one-digit numbers and that a leading dash is printed only for negative numbers. You are not allowed to construct any structured objects (no array, ArrayList, String, StringBuilder, etc) and you may not use a while loop, for loop, or do/while loop to solve this problem; you must use recursion.

This is a method problem. Write a Java method as described. Do not write a complete program or class; just the method(s) above.
