    Post how to call a string inside a while loop

    How to call a string inside the "while loop"?
    like this:
    while((line = br.readLine())!=null){
    String acc[] = line.split("-");
    String account = acc[0];
    String passcode = acc[4];
    }

    i would like to declare a string outside the "while loop" or "try catch" as the same as of the inner String.

    try{
    File file = new File("Database.txt");
     
    BufferedReader br = 
     
    new BufferedReader(new FileReader(file));
     
    String line;
     
    while((line = br.readLine())!=null){
     
     
    String acc[] = line.split("-");
     
    String account = acc[0];
     
    String passcode = acc[4];
     
    }
     
    br.close();
     
    }
     
    catch (IOException ex) {
     
    ex.printStackTrace();
     
    }

    declare a string outside the "while loop"
    The String line is declared outside of the while loop. Use that as an example of how to declare variables outside of the loop.

    Please edit the code and add indentations for nested statements to make the code easier to read.
    If you don't understand my answer, don't ignore it, ask a question.
