用拆分的JAVA解析字符串

Question

I'm trying to find an object in a list from a text file

Example:

• L;10;€10,50;83259875;YellowPaint
• -H;U;30;€12,00;98123742;Hammer
• G;U;80;€15,00;87589302;Seeds

By inserting 98123742 by input with scanner, i want to find that string. I tried to do this:

private static void inputCode() throws IOException {

        String code;
        String line = null;
        boolean retVal = false;
        System.out.println("\ninsert code: ");
        code = in.next();
        try {

            FileReader fileReader = new FileReader("SHOP.txt");


            BufferedReader bufferedReader = new BufferedReader(fileReader);

            while ((line = bufferedReader.readLine()) != null) {

                String[] token = line.split(";");

                if (token[0].equals(code) && token[1].equals(code)) {
                    retVal = true;
                    System.out.println(line);
                }
            }


            bufferedReader.close();
        } catch (FileNotFoundException ex) {
            System.out.println("impossible open the file " + fileName);
        }
         catch(IOException ex) {
                System.out.println(
                    "Error reading file '" 
                    + fileName + "'");                  

            }
           System.out.println(retVal);
        }

How can i print "-H;U;30;€12,00;98123742;Hammer" inserting "98123742" (that is the code of the product) ?

Answer 1

Why are you splitting in the first place? For such a simple usecase, and with that line format, I'd go with

line.contains(";" + code);

Not much else to do.
