Need help writing four short recursive programs: Write a program called Permutations.java that takes an integer command-line argument, n, and enumerates all permutations of the first n letters in the English alphabet. Be sure to handle exceptions of the types: i) bad user input (i.e., double, string), ii) n > 26 or n < 0. Write a program called PermutationsK.java that takes two integers, n and k, as command-line arguments and prints out all P(n,k) permutations that contain exactly k...
