Question

hello
world
in 2 lines?
thanks...

Answer 1

how do i store hello and world into a 2D array?
eg.string[][] a = { {"hello", "world"}};or if there are 2 strings, "hello world", "I'm fine" where "hello world" == a line of words from a textfile
my 2D array becomes:
string[][] a  = { {"hello", "world"}, {"I'm", "fine"}};Part of my current code is :
int i=0,j=0;
              String[][] data={};
              while ((word = b.readLine()) != null) // word is the line of 
                                                  //words retrieved from a textfile
                   StringTokenizer st = new StringTokenizer(word);
                   while (st.hasMoreTokens()) {
                        data[j] = st.nextToken();
          System.out.println("i " + i + " " + st.nextToken());
          i++;
     j++;
But it couldn't work... due to array out of bounds exception... can anyone help me modify / point out my error in my codes? thanks.
