    Default reading csv by scanner

    Hello,
    I'am reading a CSV file with a "," seperator.
    The problem is that when i have a string with a space in it, it splits
    By the way i put my data in a jtable by a defaulttablemodel.
    What is wrong in my code?

    	public CsvR()
    	{
     
    		String path = System.getProperty("user.dir") + "/src/reader.csv";
     
    		try {
    			Scanner inputStream = new Scanner(new File(path));
    			String line = null;
    			while(inputStream.hasNext())
    			{
    				line = inputStream.next();
    				String[] value = line.split(",");
    				model.addRow(value);
    				System.out.println(value[0]);
    			}
     
    		} catch (FileNotFoundException e) {
     
    			e.printStackTrace();
    		}
     
     
     
    		JPanel panel = new JPanel();
    		panel.add(new JScrollPane(table));
    		this.getContentPane().add(panel);
    		this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    		this.pack();
    		this.setVisible(true);
     
     
     
    	}

    can you post a sample String and the results of the split() that you are talking about?
    Explain what the problem is and say what you want the result to be.

    Use the Arrays class's toString() method to format the array for printing:
    System.out.println("an ID "+ java.util.Arrays.toString(theArrayName));
    If you don't understand my answer, don't ignore it, ask a question.

    How about using comma as the delimiter option in the Scanner itself rather than using the obvious split and accompanying array?
    Scanner (Java Platform SE 7 )

    using comma as the delimiter option in the Scanner
    You lose the knowledge of what line/row the data came from.
