It's like asking why you should use an electric guitar instead of an acoustic one. What happens if you've already found the item an old map leads to? It is better to compare strings at the last possible moment and to do so in memory and not to normalize strings at storage time. As far as I know, Unicode doesn't provide mapping for that, so you'll have to do it yourself the old fashioned way: String normalization is very helpful when comparing strings issued from different systems or to perform appropriate comparisons. And depending on the result we return true (or) false. Each character of both the strings is converted into a Unicode value for comparison. That last part of the code deals with them (and it can only be reached if. @DynoDimo If you've already solved the comparison issue, then take a look to the last part of my code sample; that's the way to deal with different string lengths Let me edit the code to remove all the comments.

Thanks for the help Barranka although don't fully understand what you did. String comparison "-".CompareTo("!") Since the ASCII value of @ is greater than # we get the output as c is lesser than d. A compare() method builds a comparison between two class-specific objects (x, y) with parameters. It is possible to compare only primitive characters with this method. How do I read / convert an InputStream into a String in Java? Using a proper normalization function, we should then compare 'oeuf brouille' with 'oeuf brouille' but if the normalization function is buggy or partial, the strings would mismatch. So the execution of the for loop is stopped too. Let's dive in, shall we? LocalDate.of(int year, int month, int dayOfMonth) lets you set a specific date, like the day you finally understood recursion. For these kinds of 'Siamese twin' characters, we have to apply the NFKD ("Compatibility Decomposition") normalization form that both decomposes the characters (see 'Rule #5' previously) but also maps ligatures to several 'base' characters.
