读取 TextFile 并存储在数组上

Question

我有一个数据结构课程的任务对我来说变得越来越复杂。指令是读取一个文本文件，格式为：Ana,30,120|Raul,23,178|Laura,15,164; (with 200 elements)，其中第一个值是名字、第二个年龄，第三个身高。我必须添加到 ArrayList。我有以下代码：

public void readFile()
{
    String lineas;
    try
    {
        InputStream fileInputStream = new FileInputStream("datos.txt");
        InputStreamReader reader = new InputStreamReader(fileInputStream, Charset.forName("UTF-8"));
        
        BufferedReader br = new BufferedReader(reader);
        while((lineas = br.readLine()) != null)
        {
            String[] valor = lineas.split(",");
            String name = valor[0];
            int age = Integer.parseInt(valor[1]);
            int height = Integer.parseInt(valor[2]);
            
            persona.add(new Persona(name, age, height));
            
            showMenuOptions();
        }
    } catch (FileNotFoundException ex) {
        System.out.println("File Not Found.");
    } catch (IOException ex) {
        System.out.println("Can't open the File.");
    }
}

但它只在找到时通过在末尾分隔每一行来执行搜索，但是我需要修改以便它检测由 , 分隔的每个值并在找到字符时将它们分隔 |.

Answer 1

参考下面link，可以使用split()方法

Answer 2

    public List<Person> loadPeopleFromFile(String path) {
        List<Person> result = new ArrayList<>();
        try {
            try (Scanner s = new Scanner(new File(path))) {
                s.useDelimiter("[|,;]");
                while (s.hasNext()) {
                    result.add(new Person(s.next(), s.nextInt(), s.nextInt()));
                }
            }
        } catch (IOException ex) {
            ex.printStackTrace();   
        }
        return result;
    }
