Java Open File For Reading
it cannot open the file. Here is my code public static void main(String[] args) { try { BufferedReader reader = new BufferedReader(new FileReader("test.txt")); String line = null; while ((reader.readLine()!= null)) { line = reader.readLine(); System.out.println(line); } reader.close(); } catch(Exception ex) { System.out.println("Unable to open file "); } } It goes to the exception and prints Unable to open file. Any suggestions why I cannot able to read it. java bufferedreader share|improve this question asked Oct 6 java read line file '13 at 3:38 noobcoder 1,42141131 5 Have you thought of printing the exception message instead? –Sotirios Delimanolis Oct 6 '13 at 3:38 Don't catch Exception. You won't know what type of Exception it is. Catch the specific IOException instead. –Eric Jablow Oct 6 '13 at 3:44 1 I agree with the comment above. Instead of your System.out.println, use "ex.printStackTrace()". That will give you some basic detail. If I had to guess, the fact that you have not specified the path to the file is the problem. That would result in something like a "FileNotFoundException". –EJK Oct 6 '13 at 3:45 check for the file if it exists I suspect that you dont have file in your system –ankit Oct 6 '13 at 3:49 1 You are swallowing the exception, and its message and then asking the whole community to guess the problem? Java's Exceptions can be a powerful mechanism to finding out what is going on, if it is used properly. –Amir Pashazadeh Oct 6 '13 at 3:49 add a comment| 3 Answers 3 active oldest votes up vote 1 down vote If you want to be more nearly modern, try the Java 7 solution, taken from the Paths Javadoc: final Path path = FileSystems.getDefault().getPath("test.txt"); // working directory try (final Reader r = Files.newBufferedReader(path, StandardCharsets.UTF_8)) { Strin

Join them; it only takes a minute: Sign up error opening files with Desktop in java (windows 7) up vote 1 down vote favorite I created a program that generates an excel spreadsheet (.xls), then asks if the user wants to open it immediately (if so, it uses http://stackoverflow.com/questions/6219359/error-opening-files-with-desktop-in-java-windows-7 java.awt.Desktops open() command to do so). This is working fine in windows xp, but when I tried with windows 7 it didn't work. Below is a sample of my code... Desktop myDesk = null; //if printed to file successfully and java.awt.Desktop is supported if (printed && Desktop.isDesktopSupported()) { myDesk = Desktop.getDesktop(); if (myDesk.isSupported(Desktop.Action.OPEN)) { //ask to open file int openFile = JOptionPane.showConfirmDialog(null, "File successfully created.\nWould you like the excel file to open?", "open file?", JOptionPane.YES_NO_OPTION); //try to open file if (openFile == JOptionPane.YES_OPTION) { try { myDesk.open(myFile); } catch (IOException e){ JOptionPane.showMessageDialog(null, "Problem opening file automatically, please open it yourself.", "Error", JOptionPane.ERROR_MESSAGE); } } } } On windows 7 this successfully prints to file, it shows the openFile dialogue, then shows the error dialogue. This shouldn't happen, as in order to get to the openFile dialogue Desktop and Desktop.open() should both be supported. It could possibly have something to do with trying to open a ".xls" file instead of ".xlsx" file, but excel s
