    Default Reading many files using a scanner

    Hi,
    I have some code which i want to read many files from a directory using a scanner, i can get it to read a single file, but when i edit the code to find the other files i get a FileNotFound Exception saying it can not find the name of the first file in the list! Here is the code:

    public void getInfoFromFiles() throws FileNotFoundException{
     
    File file1 = new File("C:/Users/Todd/Documents/NetBeansProjects/Project/files/");
           File[] listOfFiles = file1.listFiles();
     
      for (int i = 0; i < listOfFiles.length; i++)
      {
       FileReader file = new FileReader(listOfFiles[i].getName()); // This is the line which is most likely wrong
       Scanner src = new Scanner(file);
       while (src.hasNextLine()) {
             String line = src.nextLine();
             System.out.println(line);
    }
     
    }
     
    }
        public static void main(String[] args) throws IOException {
            stageOne test = new stageOne();
     
            test.getInfoFromFiles();

    The Error i get is

    Exception in thread "main" java.io.FileNotFoundException: hello.log (The system cannot find the file specified)
            at java.io.FileInputStream.open(Native Method)
            at java.io.FileInputStream.<init>(FileInputStream.java:106)
            at java.io.FileInputStream.<init>(FileInputStream.java:66)
            at java.io.FileReader.<init>(FileReader.java:41)
            at stageOne.getInfoFromFiles(stageOne.java:65)
            at stageOne.main(stageOne.java:80)

    Is there a way to get the scanner to read many files, or a better way to implement this!

    Thank you!

    Default Re: Reading many files using a scanner

    Try using getAbsolutePath() instead of getName(). getName() returns the name of the file only eg no path information to the file
