Java JFileChooser getAbsoluteFile Add File Extension -

-

i have issue working know if there better way of adding file extension?

what doing right is:

string filepath = chooser.getselectedfile().getabsolutefile() + ".html";

im adding extension hard coded. , saving it.

just wondering if there more robust/logical manner can implemented?

thank time.

edit: ask app portable across platforms. adding .html manually may make windows solution.

edit: think ive surfed enough know .html hard coded safe havent found documentation says dont take approach (not sure).

issue: if want save file in format, text, example how detect user selected format?

filenameextensionfilter can add filters dialog how return value file type selected?

edit: have studied this still unclear how retrive user selected file type.

edit: rephrase of issue:

alt text http://img98.imageshack.us/img98/4904/savef.jpg question how can retrieve/find out 1 of 2 filters user has selected save format. html or jpeg? how retrieve info jfilechooser? thank you.

edit: found out: has jfilechooser.getfilefilter() still welcome.

edit: getfilefilter() , filenameextensionfilter comparasion solved issue.

here code snippet solves issue:

jfilechooser chooser = new jfilechooser(); chooser.setmultiselectionenabled(false); chooser.setacceptallfilefilterused(false);  filenameextensionfilter filter = new filenameextensionfilter("html documents", "htm", "html"); chooser.setfilefilter(filter);  int option = chooser.showsavedialog(chatgui.this); if (option == jfilechooser.approve_option) {     // set document parsed html     styleddocument doc = (styleddocument)textpanehistory.getdocument();     htmleditorkit kit = new htmleditorkit();      bufferedoutputstream out;      try {         system.out.println(chooser.getfilefilter());          if (chooser.getfilefilter() == filter)             system.out.println("ha ha");     } }

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
