Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    BufferedReader in = null;//from   ww  w  .  j a  v a  2  s.  co m
    in = new BufferedReader(new FileReader("fileeditor.txt"));
    StreamTokenizer st = new StreamTokenizer(in);
    st.eolIsSignificant(false);
    // remove comment handling
    st.slashSlashComments(false);
    st.slashStarComments(false);

    while (st.nextToken() != StreamTokenizer.TT_EOF) {
        if (st.ttype == StreamTokenizer.TT_NUMBER) {
            // the default is to treat numbers differently than words
            // also the numbers are doubles
            System.out.println((int) st.nval);
        } else {
            System.out.println(st.sval);
        }
