Question

In your first program, write a recursive methodcalled doubleDigits that accepts an integer n as a parameter and returns the integer obtained by replacing every digit of n with two of that digit. For example, doubleDigits(348) should return 334488. The call doubleDigits(0) should return 0. Calling doubleDigits on a negative number should return the negation of calling doubleDigits on the corresponding positive number; for example, doubleDigits(–789) should return –778899. 2. Write a recursive method called writeChars that accepts an integer parameter n and that prints out a total of n characters. The middle character of the output should always be an asterisk ("*"). If you are asked to write out an even number of characters, then there will be two asterisks in the middle ("**"). Before the asterisk(s) you should write out less-than characters ("<"). After the asterisk(s) you should write out greater-than characters (">"). Your method should throw an IllegalArgumentException if it is passed a value less than 1. Test your method in the program 2. For example, the following calls produce the following output:writeChars(1); *
