String inOrder(String str1, String str2, String str3): Given 3 input strings, return a single string with the 3 input strings in alphabetical order separated by commas. HINT 1: See the compareTo and compareToIgnoreCase methods in the Help section (Strings). Read the documentation carefully. str1.compareTo(str2) returns zero if the two strings are equal, a negative number (NOT -1) if str1 precedes str2 alphabetically, and a positive number (NOT +1) if str1 follows str2 alphabetically. HINT 2: You know how to swap two values to put them in the proper order. Here you have to figure out how to swap three values. RUBRIC: It is not enough to just solve the problem. Make sure you use PROPER INDENTATION. You MUST use CURLY BRACKETS for all loops and if/else statements. Also, the more EFFICIENT your solution, the higher your grade. If you have extraneous (superfluous / unnecessary) code, deductions will be taken.
