How to know how many positions an array has in Java?

Question

Look at the picture;

I’m uploading a CSV file, and I’m already able to count how many lines there are, in our context are three lines as shown in the code below;

However I need now and how to get the maximum number of positions, I’m not sure how to catch, I know that by doing a debug I can know that the maximum number of positions is 10 as shown in the figure below;

I need to know how to create a line of code to get the amount of positions; this is my algorithm;

    File arquivoLeitura = new File(getArquivo());
LineNumberReader linhaLeitura = new LineNumberReader(new FileReader(arquivoLeitura));
linhaLeitura.skip(arquivoLeitura.length());
int qtdLinha = linhaLeitura.getLineNumber() + 1;

BufferedReader leitor = new BufferedReader(new InputStreamReader(new FileInputStream(getArquivo())));

String linha = null;

List<TotalIndicios> listaTotalDeIndicios = new ArrayList<TotalIndicios>();
List<IndiciosEntity> listaIndiciosEntity = new ArrayList<IndiciosEntity>();

for (int indiceDeIndicios = 1; indiceDeIndicios <= qtdLinha; indiceDeIndicios++) {

    linha = leitor.readLine();
    String[] dadosCSV = linha.split(VIRGULA);
    //vai fazer alguma coisa......
}

Answer 1

This line in your code that makes the split, already have all the elements separated, so just use the property length to obtain the quantity:

String[] dadosCSV = linha.split(VIRGULA);
Int quantidade = dadosCSV.length;

Answer 2

Using the length method returns how many positions there are in an array.

dadosCSV.length
