Which Java IO class is better to use for a simple shell interpreter? -

-

i new java io library, have trouble choosing right class purposes. write simple shell client file transferring server. client should understand 3 commands: list files in remote directory (optionally can take nested directory path argument), download specified file (with file path required argument) , end session (a separate command). concerned handling user's input @ moment. questions are:

  1. should read whole line of input, tokenize , logic, or better tokenize input comes , make immediate decisions based on it?
  2. what class should use tokenize input: scanner or streamtokenizer? or taking account commands simple use bufferedreader read line, split string "\\s+" pattern?

the questions may seem subjective in way want diminish confusion , understand specific use cases of io classes.

  1. considering commands basic, reading whole input , tokenizing require lot of efforts. better tokenize input , take decisions required.

  2. i think bufferedreader sufficient serve purpose here. make code easy. when working on taking input csv file , tokenizing display graph used same. logic parsing string goes below:- 

      string splitby = ";"; // using csv file below used ";" splitter. can change per needs    bufferedreader br = new bufferedreader(new filereader("file.csv"));   string line = br.readline();   while((line = br.readline()) != null)   {        string[] b = line.split(splitby);        //take actions need perform   }   br.close();

hope answers question. let me know if more details required.

this error has shown on many times, seems. prominent answer issue seems restkit 0.20 — coredata: error: failed call designated initializer on nsmanagedobject class however, solution posted doesn't work me. let's start beginning: i want upload file server. want parse response make sure uploaded. if not, try again later. model has boolean variable called nsnumber *senttoserver purpose (in coredata, bool saved nsnumber ) . because don't know whether sending going successful, save entity coredata model first before sending via restkit. when post request successful, server returns json string this: {"id":14,"created":true} notice that, of course, id not set on coredata model yet, both id , created new informations model. here's model: @interface recording : nsmanagedobject @property (nonatomic, retain) nsstring * audiofilepath; @property (nonatomic, retain) nsdate * createdat; @property (nonatomic, retain) nsstring * deviceid; @
