How to Store Splitted Strings in an Arraylist?

Question

I’m doing a job where I need to save the information from a current account, I need to read the information from a file (text) and split this information into account code, name and balance. Also, I need to save this information to an Array.

My problem is this: I cannot split this information to save to an Array. Could you help me?

I created a reader function();

public void leitor() throws FileNotFoundException, IOException{ 
    try (
             BufferedReader reader = new BufferedReader (new FileReader ("arquivo.txt"));
        ) {
             for (String line = reader.readLine(); line != null; line = reader.readLine()) {
                 **String saida = line.split(";");**
                 System.out.println(saida);
             }
        }
}

Which just reads the file information, however, I can’t crack that information.

Answer 1

See a simple way using the static method Arrays.asList(), but "splintando" spaces:

String str = "A HBO anunciou a sétima temporada de Game of Thrones";       
ArrayList<String> arrayList = new ArrayList<String>(Arrays.asList(str.split(" ")));

To be separated by a point and a comma, but to place .split(";");

Answer 2

instead of doing String saida = line.split(";");

ago

var saida = line.split(';');

or else declare string[] saida
