The below image shows the Morse code for the alphabets from A to Z. SOS full form is Save Our Souls created as a universal distress signal represents danger. There are some famous words considered as important feature of Morse code like ‘SOS’. The language has always been the barrier for the Morse code, as it’s hard to perform the code for diacritic characters in other language. It is mainly used in the radio and ocean communication and also a part of training for soldiers. The Morse code is available for encoding alphabets and numbers. ![]() In the international morse code, the original version is modified by removing spaces and designing the dashes in a specific length. The Morse code is available in two versions, the original and the international morse code. A Morse code can be performed by tapping, flashing light or writing. It was most used at the time of World War II. and further used in telegraphy for transferring secret information. * a decoded version of the provided message.Morse code is a system of communication to encode any character in two different durations of signals called Dots and Dashes. * message to be decoded assuming that the message contains only '_' and '.', assuming that the message given contains no foreign chars that don't exist in the database given. * Method to decode a given Message based on the given database and the morse code logic. Public static Morse getInstance(final Path dataBaseFile) * a class instance of type Morse} linked with a database of user's choice via a Path}. * dataBaseFile the path to the database which contains the actual decoding and encoding table of the morse code. * This Method creates a class instance of type Morse} if not created before else return the already created object. Private static Morse defaultObj, pathObj, objWithSeparator, objWithCharSet Singleton Pattern via Lazy Instantiation = private constructor static object that will be created once!. Private String charSeparationRegex = " " ![]() Private Charset cs = StandardCharsets.UTF_8 * This class represents Encoder and Decoder for Morse code. Import javazoom.jl.decoder.JavaLayerException The program takes regex into consideration when it comes to reading the database file as the regex would act as a separator between the actual letter and the sequence of dots and dashes. Structure wise I used the Singleton Design pattern To allow the user of having a limited amount of objects thus there is no need to create an object to encode/decode if it already exists.įlexible thus it can read from the desired database.Ĭompatible with all kinds of allowed CharSet backed by java(when using the right charset to read a certain file).Īudio playback to help people learn to understand morse code by hearing!.Ībility to write results into a file by the desired path. refĪs many online Morse translators, use the character '/' or a ',' to be translated into space I used the '\t'. This constraint enables bimaps to support an "inverse view", which is another bimap containing the same entries as this bimap but with reversed keys and values. I used the BiMap for the following reason:Ī bimap (or "bidirectional map") is a map that preserves the uniqueness of its values as well as that of its keys. ![]() ![]() Recently I wanted to create a morse encoder/decoder with playback ability, the program needs java version >= 11 to run.
