Java Swing JFileChooser f� fil til at ende med valgte fil type fra file extension

Thu, 17 Jul 2014 16:48:13 GMT

Hej alle sammen, jeg har f�et det problem at jeg ikke kan f� mine filer til at ende med den valgte fil type n�r den skal gemmes.

Foreksempel : Jeg v�lger i JFileChooser at det skal v�re en .html fil (og ikke bare alle fil typer). Og n�r jeg s� gemmer filen ender den ikke med .html men med .asm eller ikke noget.

Nogen som vil v�re s�de at hj�lpe med det?

Kode

Java kode

 JFileChooser jchooser = new JFileChooser();
 FileNameExtensionFilter asm = new FileNameExtensionFilter("Assembly (.asm)", "asm");
 FileNameExtensionFilter cpp = new FileNameExtensionFilter("C++ (.cpp)", "cpp");
 FileNameExtensionFilter cpph = new FileNameExtensionFilter("C++ Header (.h)", "h");
 FileNameExtensionFilter cpp1 = new FileNameExtensionFilter("C++ (.cc)", "cc");
 FileNameExtensionFilter cpp2 = new FileNameExtensionFilter("C++ (.cxx", "cxx");
 FileNameExtensionFilter c = new FileNameExtensionFilter("C (.c)", "C");
 FileNameExtensionFilter css = new FileNameExtensionFilter("CSS (.css)", "css");
 FileNameExtensionFilter HTML = new FileNameExtensionFilter("HTML (.html)", "html");
 FileNameExtensionFilter PHP = new FileNameExtensionFilter("PHP (.php)", "php");
 FileNameExtensionFilter JS = new FileNameExtensionFilter("JavaScript (.js)", "js");
 FileNameExtensionFilter java = new FileNameExtensionFilter("Java (.java)", "java");
 FileNameExtensionFilter javas = new FileNameExtensionFilter("Java Server Page (.jsp)", "jsp");
 FileNameExtensionFilter xml = new FileNameExtensionFilter("XML (.xml)", "xml");
         
 jchooser.setApproveButtonText("gem");
         
 jchooser.setFileFilter(asm);
 jchooser.setFileFilter(c);
 jchooser.setFileFilter(cpp);
 jchooser.setFileFilter(cpph);
 jchooser.setFileFilter(cpp1);
 jchooser.setFileFilter(cpp2);
 jchooser.setFileFilter(css);
 jchooser.setFileFilter(HTML);
 jchooser.setFileFilter(JS);
 jchooser.setFileFilter(java);
 jchooser.setFileFilter(javas);
 jchooser.setFileFilter(PHP);
 jchooser.setFileFilter(xml);
         
 int action = jchooser.showSaveDialog(this);
  if (action != JFileChooser.APPROVE_OPTION)
     return;
         
 File fi = jchooser.getSelectedFile();
 if(!fi.getName().endsWith(".asm")) {
  fi = new File(fi.getAbsolutePath() + ".asm");
 } 
 
 if (!fi.getName().endsWith(".cpp")) {
  fi = new File(fi.getAbsolutePath() + ".cpp");
 } 
 
 if (!fi.getName().endsWith(".h")) {
  fi = new File(fi.getAbsolutePath()+ ".h");
 }
 
 if (!fi.getName().endsWith(".cc")) {
  fi = new File(fi.getAbsolutePath() + ".cc");
 }
 
 if (!fi.getName().endsWith(".cxx")) {
  fi = new File(fi.getAbsolutePath() + ".cxx");
 }
 
 if (!fi.getName().endsWith(".c")) {
  fi = new File(fi.getAbsolutePath() + ".c");
 }
 if (!fi.getName().endsWith(".css")) {
  fi = new File(fi.getAbsolutePath() + ".css");
 }
 
 if (!fi.getName().endsWith(".html")) {
  fi = new File(fi.getAbsolutePath() + ".html");
 }
 
 if (!fi.getName().endsWith(".php")) {
  fi = new File(fi.getAbsolutePath() + ".php");
 }
 
 if (!fi.getName().endsWith(".js")) {
  fi = new File(fi.getAbsolutePath() + ".js");
 }
 
 if (!fi.getName().endsWith(".java")) {
  fi = new File(fi.getAbsolutePath() + ".java");
 }
 
 if (!fi.getName().endsWith(".jsp")) {
  fi = new File(fi.getAbsolutePath() + ".jsp");
 } 
 
 if (!fi.getName().endsWith(".xml")) {
  fi = new File(fi.getAbsolutePath() + ".xml");
 }
         
 BufferedWriter bf = null;
         
 try {
  bf = new BufferedWriter(new FileWriter(fi));
             
  editor.getJTP().write(bf);
 } catch (IOException ex) {
  ex.printStackTrace();
 }
         
 finally {
  if (bf != null) {
   try {
    bf.close();
   } catch (IOException e) {
    e.printStackTrace();
   }
  }
 }

Det skal lige meddeles at der ikke kommer nogen fejl eller advarsler.
