some suggestions:

- do not call a class interface. That name is taken and specified, you will ruin your day with that.

- Also: class names start with a capital letter: Application

- name your components. t and r1...r3 are not names. call the txtField or btnSearch.

and now some questions:

- what kind of folder? Folder of the OS of the machine you are working on?

- what kind of "path change"?

the class name is interfac without "e"

yes folder in my PC
i put folder " myFiles " in my project folder and put into 3 folders
example: myFiles/political

and i have error in (Handler)
private class Handler implements ActionListener
how can solve it?

and i have error in (Handler)

how can solve it?

probably because the inherited method is called "actionPerformed".

please also read about it here: ActionListener[^] @ the Java Tutorials

You can start the Windows File Explorer by telling the system to do so:

Java

try { 
  Process oProcess = new ProcessBuilder("explorer.exe", "/select,C:\\directory\\political").start();  // check out the "\\", the backslash is a masking tag and needs to be masked to be used "normal"
  // oProcess.waitFor(); // only if you want your app to wait for the filexplorer to finish
}
catch(Exception oException){
  oException.printStackTrace(); // to get full exception text
}

Solution 3

C#

r1.addActionListener(new ActionListener() {

            public void actionPerformed(ActionEvent e) {
                reading.read("political news");
            }});
        r2.addActionListener(new ActionListener() {

            public void actionPerformed(ActionEvent e) {
                reading.read("economic news");
            }});
        r3.addActionListener(new ActionListener() {

            public void actionPerformed(ActionEvent e) {
                reading.read("social news");
            }});

- Update Component in GUI ( like Label.setText("value");
- call repaint() for region (JPanel/JFrame)

mss.noor 22-Dec-12 7:31am

but i can't understand how i can get the document after finding similarity from directory vectors

TorstenH. 22-Dec-12 7:43am

- what kind of document?
- have you searched only on how to read the document? What have you tried?

mss.noor 22-Dec-12 11:32am

i have many error , because that i can't test the code
but i can read it line by line ,,,it's work

txt file that contain many short of paragraph
like:
d1
....
d2
..
.
.

i want to read it and get similarity with the query that the user enter it in the textfield then the program will display which paragraph(document) that contain this query

Stringtokenizer
Comparing Strings

or a bit more advanced / more elegant:

You can display HTML in most Java Swing Components: How to Use HTML in Swing Components
Might be useful to present the search results.
