我正在嘗試編寫一個里程跟蹤器程序來跟蹤用戶步行、跑步或游泳的距離。該程序在會話期間要求用戶輸入步行距離，將其存儲在雙精度中，從文件中讀取有關先前步行總距離的數據，將最新會話的距離添加到過去的總距離以創建新的總距離，并將該總數寫入存儲它的文件以供將來使用。編寫代碼時，當我嘗試將它們指向文件時，IDE 在打印寫入器和掃描儀上顯示錯誤：Scanner reader = new Scanner(storage); //error at second ScannerPrintWriter writer = new PrintWriter(storage); // error at second PrintWriter錯誤顯示為“FileNotFoundException”當放置在 try 塊中時，錯誤消失，程序在運行時打印 catch 塊錯誤報告：catch(FileNotFoundException e){            System.out.println("Check that the text file is in the correct directory.");            e.printStackTrace();        }這是我使用 PrintWriter 編寫的第一個程序，因此將不勝感激一些指針和關于我做錯了什么的解釋。這是完整的代碼：import java.io.File;import java.io.PrintWriter;import java.io.FileInputStream;import java.util.Scanner;import java.io.IOException;import java.io.FileNotFoundException;import java.lang.String;public class Main {    public static void main(String[] args) {        //gets interval data from user        System.out.println("Please type the amount of miles walked.");        Scanner input = new Scanner(System.in);        double inMiles = input.nextDouble();            //creates file and scanner that reads to file            File storage = new File ("Mile Tracker//Mile.txt");        try {            storage.createNewFile();        }        catch(IOException e ){            System.out.println("File not created.");        }        try {            Scanner reader = new Scanner(storage);            //takes data from file and sets it to a variable            double Miles = reader.nextDouble();            double TotalMiles = Miles + inMiles;            //PrintWriter reader = new PrintWriter( file );            //PrintWriter that clears the file            /*PrintWriter clearwriter = new PrintWriter(storage);            clearwriter.print("");            clearwriter.close();*/            PrintWriter writer = new PrintWriter(storage);            writer.print(TotalMiles);        }     }}
