What should i add so that it will print the code and not the address?

Question

This program is to read from a file. I would like to print out the code and not the address location. What should be added to my program?

        try {
            FileInputStream fileReader = new FileInputStream("Results.txt");
            BufferedReader reader = new BufferedReader(new InputStreamReader(fileReader));
            ArrayList<Result> myList = new ArrayList<>();
            String line = reader.readLine();

            String strLine;
            String[] lines = line
                    .replace("[", "")
                    .replace("]", "")
                    .split(",");
            int flag=1;
            while ((strLine = reader.readLine()) != null) {
                if (flag == 1) {
                    for (String l : lines) {
                        System.out.println(l.trim());
                    }
                }
                System.out.println();
                System.out.println(strLine
                        .replace("[", "")
                        .replace("]", "")
                        .split(","));

                flag++;
            }

        }
        catch (Exception e) {
            e.printStackTrace();
        }

Below are the output of my program. It shows that there are 2 address location that have been printed out.I would like to print the codes not the location

You should use `Arrays.toString` for the string arrays retrieved after string `split` method -- then you'll see the contents of the arrays. — Nowhere Man, Jul 01 '20 at 23:00

Use java.util.Arrays.toString to print the elements of a one-dimensional array.

System.out.println(Arrays.toString(strLine.split(",")).replace("[", "").replace("]", "").replace(",", ""));

It works but the "[" "]" and "," is still there – Elbert Jn Jul 02 '20 at 07:58
@ElbertJn I have updated my answer. – Unmitigated Jul 02 '20 at 13:04
It removes the "[" but the "," is still there ```< 107 | Chemistry | Credit Hours: 3 | Grade: A >, < 108 | physics | Credit Hours: 3 | Grade: B+ >, < 109 | Finance | Credit Hours: 3 | Grade: A- >```. What should be added to split it? – Elbert Jn Jul 02 '20 at 17:59
@ElbertJn How about now? – Unmitigated Jul 02 '20 at 18:00
