Norm Radder wrote:An explanation for the magic numbers: 48 and 55 would be useful. Could the 48 be '0'? Is the 55 'A' - 10? Char values are numeric and can be used directly without using their int values.The explanation is in the comments! But basically it's the difference between the ASCII code of the characters and their corresponding index in the array, so: ASCII of '0' = 48 Index of 1st digit in array = 0 Diff = 48 - 0 = 48 ASCII of 'A' = 65 Index of 1st letter in array = 10 Diff = 65 - 10 = 55.

ASCII of '0' = 48 Index of 1st digit in array = 0 Diff = 48 - 0 = 48 ASCII of 'A' = 65 Index of 1st letter in array = 10 Diff = 65 - 10 = 55 But '0' is not 0. A char is a number and you can do arithmetic with it. You can write n − '0' and there will be no need for the literal 48. The same applies to 'A'. By using 'A' and 'a' you can enhance your application to support uppercase and lowercase writing.

Or even use n% 0x20. You may find it is easier to use hex numbers rather than decimal. Junilu has already told you much of that. Are You Smart Enough To Work At Google Book Pdf. Piet Souris wrote:My advice: don't use arrays that need index juggling. Simply use: String[] morseCodes = new String[256], (or small enough), and get the morse code by: morseCode = morseCodes(char). If you think that is wasting too much memory, then use a HashMap (or two).

That's a reasonable alternative although you'd still need to juggle index values to initialize the elements to their corresponding codes. The lookup will be straightforward though. You could also use a proper Map.
