    Char reading

    I'm trying to read a string from the console like

    java TestFile arg1 arg2 .....

    and I want then to split arg1 into 'a','r','g','1' , to insert into a Stack.

    How do I do such conversion ?

      import java.lang.*;

      public class StringSplitter
      {
      public static void main(String [] args)
      {
      byte [] charArr;
      charArr=args[0].getBytes;
      push(charArr[0]);
      }
      }

      here the array of bytes is single chars .... if args[0] = "karthik"
      charArr[0]='k'
      charArr[0]='a'
      charArr[0]='r'
      ..
      ..
      ..

              Hi Everybody in comp.lang.java! !!


              I'm quite new here so please Nuno let me first introduce myself, short...

              My name is Piotr (Peter in Eglish), but I'm often using "piotr" in my
              signature, to express my growing (not grown yet) experience in the
              Computer Science... :-)
              I am from Poland and I'm (rather occasional) a reader of this group
              since last a few months.
              I've been working since 10 years writing software mostly for OS/400
              based machines, so my experience is divided into many different
              programming techniques and technologies including Java (this one since
              about six years).
              Last a couple of months I'm also a quite active writer for the "Polish
              version" of this group (pl.comp.lang.j ava) where everyone understanding
              our language is welcome also...
              I can't make a promise for writing here, but I hope nobody will be
              offended with me for my possible future posts here.

              Here is also my personal greetings exchanged with all of the reputable
              members of this group...



              OK, Nuno..., lets back to your problem... I've decided not to answer you
              personally because I think You should express a little more precisely
              Your questions, and probably most of the people writing here, have no so
              much time (I guess...) to talk to you on details of your question, so do
              I...


              My answer:

              Use the following as an example for your TestFile.main method body:

              public static void main(String[] args) {
              ....

              Stack stack = ... // instantiate your Stack here

              for(int i = 0; i < args.length; ++i) {
              String a = args[i]; // (i + 1)th argument

              for(int ai = 0; ai < a.length(); ++ai) {
              char c = a.charAt(ai); // (ai + 1)th character of a

              // now you can add c into your stack...

              // assuming your Stack is java.util.Stack ...
              //...you can do it this way:
              stack.push(new Character(c));

              }

              // and here you can (optionally) do some separation...
              //...of your arguments stream :) eg:
              if ((i + 1) < args.length)
              stack.push(new Character(' '));

              }

              ....
              }


              Ohh, of course..., you have to consider using StringBuffer or more
              "advanced" stack for your particular needs.

                  Oh... I'm asking everybody to forgive my non-perfect English... this is
                  not my native language...

                  I've been working for 10 years..., and probably more "flowers" like
                  this..., I'm sorry... :-)
