我有两个班：Ristorante和Ristoratori。两者都使用外部库进行thr I / O。这两个类已经编译，但是当Ristoratori（引用Ristorante）启动并询问我读取文件的路径时，会出现一些错误。
Ristorante：
public class Ristorante implements Serializable {
static ConsoleInputManager in = new ConsoleInputManager();
static ConsoleOutputManager out = new ConsoleOutputManager();
private static final long serialVersionUID = 7613409875169727612L;
String nome ;
String via ;
String nciv ;
String città ;
String prov ;
String CAP ;
String ntel ;
String web ;
String tipris ;
ArrayList<String> listagiud = new ArrayList<String>() ;
public Ristorante(String nome,String via, String nciv,String città, String prov,String CAP, String ntel,String tipris, String web) {
this.nome = nome;
this.via = via;
this.nciv= nciv;
this.città = città;
this.prov = prov;
this.CAP = CAP;
this.ntel = ntel;
this.tipris = tipris;
this.web = web;
}
public void addGiud(String giud) {
listagiud.add(giud);
}
public ArrayList<String> getCommenti() {
out.println(listagiud);
return this.listagiud;
}
public String getNome() {
return this.nome;
}
public String getTipris() {
return this.tipris;
}
public String getInfo() {
String info = "Nome : " + this.nome + " , Via : " + this.nciv + " , Città : " + this.città + " " + this.CAP +
" , Provincia : " + this.prov + " , Numero di telefono : " + this.ntel + " , Cucina del ristorante : " + this.tipris + " , Sito web : " + this.web + " , Commenti dagli utenti : " + this.listagiud.toString();
out.println(info);
return info;
}
public static void main(String[] args){
System.out.println("ris partito");
}
}
Ristoratori：
public class Ristoratori {
static ConsoleInputManager in = new ConsoleInputManager();
static ConsoleOutputManager out = new ConsoleOutputManager();
static HashMap<String,ArrayList<String>> map = new HashMap<String,ArrayList<String>>();
static String path2;
static File EatAd;
static String selnome = "";
static ArrayList<Ristorante> listaris = new ArrayList<Ristorante>();
public static void putRistorante (ArrayList<Ristorante> listaris) {
String nome = in.readLine("Inserire nome ristorante ");
String via = (in.readLine("Inserire via del ristorante "));
String nciv =(in.readLine("Inserire n° civ del ristorante "));
String città =(in.readLine("Inserire città del ristorante "));
String prov =(in.readLine("Inserire sigla provincia del ristorante "));
String CAP =(in.readLine("Inserire CAP del ristorante "));
String ntel =(in.readLine("Inserire n° telefono del ristorante "));
String web =(in.readLine("Inserire sito web del ristorante "));
String tipris =(in.readLine("Inserire tipologia di cucina del ristorante(italiano-fusion-ecc) "));
Ristorante r= new Ristorante(nome, via, nciv, città, prov, CAP, ntel, tipris ,web);
listaris.add(r);
listaris.forEach(k -> k.getInfo());
}
@SuppressWarnings("unchecked")
public static ArrayList<Ristorante> readDati (File EatAd) throws IOException, ClassNotFoundException {
ObjectInputStream is = new ObjectInputStream(new FileInputStream(EatAd));
listaris = (ArrayList<Ristorante>) is.readObject();
is.close();
return listaris;
}
public static void writeDati (File EatAd, ArrayList<Ristorante> listaris ) throws IOException {
ObjectOutputStream os = new ObjectOutputStream(new FileOutputStream(EatAd));
os.writeObject(listaris);
os.close();
}
public static void main(String[] args) throws IOException, ClassNotFoundException {
path2 = in.readLine("Indicare percorso della cartella");
path2 += "\\EatAdvisor.dati";
EatAd = new File(path2);
if (EatAd.exists() == false) {
EatAd.createNewFile();
out.println("File da creare !");
}
else {
readDati(EatAd);
out.println("File trovato !");
}
while (in.readSiNo("Inserire ristorante ? ")) {
putRistorante(listaris);
}
writeDati(EatAd, listaris);
out.println("File aggiornato \n" + "Chiusura applicazione ! ");
}
}
这是终端，请帮助我，因为我找不到解决此问题的方法，因为当我从Eclipse开始时，一切都很好：
