Text message abbreviation decoder (Java)

(1) Complete the following method:

/** * Decodes the text abbreviation. * * @param textAbbr Text abbreviation. * @return The decoded abbreviation if known. Otherwise, returns Unknown. */ public static String decTextAbbr(String textAbbr) { // FILL IN BODY }

If the parameter matches a known text message abbreviation, return the unabbreviated form, else return: Unknown. Support two abbreviations:

LOL -- laughing out loud, and

IDK -- I don't know.

For example:

decTextAbbr("LOL") 

returns

laughing out loud

(2) Write a testing method to verify this method works for all expected inputs:

/** * Runs tests on the decTextAbbr method. */ public static void testDecTextAbbr() { System.out.println( "decTextAbbr(\"LOL\") expected 'laughing out loud', actual '" + decTextAbbr("LOL") + "'"); System.out.println( /* FIX ME */); System.out.println( /* FIX ME */); } 

Run this test method from the main method to verify the decTextAbbr method is working correctly.

(3) Expand the method to also decode these abbreviations.

• IMHO -- in my humble opinion
• TMI -- too much information
• BFF -- best friends forever
• ROFL -- rolling on floor laughing
• LMK -- let me know

extend the testDecTextAbbr() method to also verify these cases work correctly. When complete, your testDecTextAbbr() method should have at least 6 tests.
