Question

JAVA

Overview

Create a method public static void spongeBobify(String inputPath, String outputPath, Mode mode) that will convert a file to Mocking Sponge Bob text in 3 different modes.

• EveryOther
  • capitalize the first letter of the string
  • capitalize every other letter (ignoring non-letter character like punctuation and spaces).
  • non-letter characters don't count toward the every other count
  • Example: mocking sponge bob! → MoCkInG sPoNgE bOb!
• Vowels
  • capitalize every vowel (not including y)
• Random
  • capitalize each letter with a probability of 35%.

The enum definition is shown below.

enum ConversionMode { EveryOther, Vowels, Random }

Input File Format

The input file will be a text on multiple lines that may contain letters, numbers, and punctuation.

Output File Format

The output file will contain the same number of lines but each line will be SpongeBob-ified.
