A function can not be used in Applet.what' wrong?

Question

Here is a function.
          private String LoadFile() {
String input;
          String output="sssssdsdsddf";
          try{
          FileReader f=new FileReader("shu.txt");
BufferedReader in = new BufferedReader(f);
while ((input = in.readLine())!= null){output=output+input;}
          in.close();
          }catch(IOException e) {   
               System.err.println("Exception caught: " + e.getMessage());
return output;
It can be used in Java Application,and work well.but can not be used in Applet,it does not work.what's wrong?

Answer 1

Don't you think it would be a bit of a security risk if any applet you downloaded from the web (unknowingly) could read/write to your file system....
Applets have strict security applied to them, and file i/o is one of the restrictions. There are ways around it, but for the moment I'd suggest you build a bridge and get over it.
