Answer 1

The error occurs because you are trying to access fileContent outside the try catch.

Declare the variable before to be accessible:

public class ShowDoMilhao {

    public ShowDoMilhao() {

    }

    public static void main(String[] args) throws IOException {

        String file1 = "Facil.txt";

        String[] fileContent;
        try {
            ReadFile file = new ReadFile(file1);

            fileContent = new String[file.readLines()];
            fileContent = file.OpenFile();

        }catch (IOException e) {
            System.out.println(e.getMessage());
        }

        System.out.println(fileContent[0]);
    }
}

Note that I performed variable declaration outside the try catch, without this it is visible only in the scope of try catch
