一旦我運(yùn)行代碼來讀取數(shù)據(jù)，程序執(zhí)行就不會(huì)循環(huán)回來。我嘗試改變放置 try catch 語句和finally 語句的位置，并且所有中斷方式都會(huì)繼續(xù)。    long code;    char choice;    Cars CarSales = new Cars(); //It creates a Java object and allocates memory for it on the heap.    Scanner sc = new Scanner(System.in);    System.out.println("   -----CARS SALES YARD------"); //The println is a method of java.io.PrintStream.    do {        System.out.println("1. Add item");        choice = sc.nextLine().charAt(0);        switch (choice) {     //switch statement allows a variable to be tested for equality against a list of values.         case '6':            try{            CarSales.ReadData();            continue;            }            catch(IOException e){                     System.out.println("Error reading file '" );                     continue;            }        default:            System.out.println("Invalid Selection\n");        }    } while (choice != '6'); //while loop statement repeatedly executes a statement as long as a given condition is true    sc.close();public void ReadData() throws IOException{//This Method is in the Cars classString fileName = "input.txt";String line = null;FileReader fileReader = new FileReader(fileName);BufferedReader bufferedReader = new BufferedReader(fileReader);while((line = bufferedReader.readLine()) != null) {            System.out.println(line);    }   bufferedReader.close();   System.out.println("TRY");盡管程序執(zhí)行只是停止循環(huán)，但沒有錯(cuò)誤消息。
