我应该添加什么才能打印代码而不是地址？

Question

这个程序是从文件中读取的。我想打印出代码而不是地址位置。我的程序应该添加什么？

        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();
        }

下面是我的程序的输出。它显示有 2 个地址位置已打印 out.I 想打印代码而不是位置

Answer 1

使用java.util.Arrays.toString打印一维数组的元素。

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