Hash tree using Strings

[IgorM]

I'm creating a hash tree that reveives Strings with 16 char characters. The problem is that each char having 8 bits the string should have 128 bits, but when I read words from a txt file, add blank characters to add up 16 and convert it to a string of 0 and 1 I get only 127 digits. What's going on?

 

  

  public static void main(String[] args) {

        ArvorePatricia dicionario = new ArvorePatricia(127);

        try {
            ExtraiPalavra palavras = new ExtraiPalavra(
                    "C:\\Users\\olive\\Documents\\NetBeansProjects\\TP01\\src\\tp01\\exemplo1.txt");
            String palavra = null;
            long l;
            while ((palavra = palavras.proximaPalavra()) != null) {
                if (palavra.length() < 16) {
                    for (int i = palavra.length(); i < 16; i++) {
                        palavra += ' ';
                    }
                }
                String binary = new BigInteger(palavra.getBytes()).toString(2);
                System.out.println("inseriu: " + binary);
                dicionario.insere(binary);
            }

A search about using getBytes then toString on the byte array points me to this: https://stackoverflow.com/questions/15407201/getbytes-then-tostring-dont-give-the-same-result-each-time

Should be i <= 16 The for loop is getting to 15 adding one then ending the loop.

Arrays are 0 based so that's not a problem. Plus OP should be getting 90 bits instead of 127, assuming the entire input needed padding

Yeah, the for isn't the issue. I'm going to try the suggestion from the link you sent.
