    Default I need help with this file reader code

      try{
       // Open the file that is the first 
       // command line parameter
       FileInputStream fstream = new FileInputStream("Inventory2.dat");
       // Get the object of DataInputStream
       DataInputStream in = new DataInputStream(fstream);
       BufferedReader br = new BufferedReader(new InputStreamReader(in));
       String strLine;
       //Read File Line By Line
       while ((strLine = br.readLine()) != null)   {
       // Print the content on the console
       ind.append(strLine);
       }
       //Close the input stream
       in.close();
         }catch (Exception e){//Catch exception if any
       System.err.println("Error: " + e.getMessage());
       }

    The code works but it does not display the information correctly. its in .dat file as:
    Item Number
    item Quantity
    Item Color

    but instead it shows up as :

    ItemNumberItemQuantityItemColor

    how do i change it to show up correctly?

    Where does the code print out what you show in the post?

    If you want endline characters between the lines read from the file so each line will display on a new line, you need to append the endline character("\n") to the String after each line that is read.
    If you don't understand my answer, don't ignore it, ask a question.
