How could I limit if I only want like 3 rows and 2 cols to be stored from the file with streams ?

class Asd{
    String [][] t;

    public Asd(String data) throws IOException {
        t= Files.lines(Paths.get(data))
                .map((line) -> line.trim().split(""))
                .toArray(String[][]::new);
    }

>Solution :

Something like:

t= Files.lines(Paths.get(data))
        .limit(3)   // limit rows
        .map((line) -> Arrays.stream(line.trim().split("")).limit(2).toArray(String[]::new))  //limit cols
        .toArray(String[][]::new);
