hi,
i am just trying to print all the 'method' names of java files from my folder. its not showing any error but during testing i face different kinds of problem for each output with same code..

in addition, i might mention how program suppose to work...
->it reads every files line by line and find 1st parentheses ( "(" ), if have any then get the whole line before parentheses. Then locate any return value has or not in those line, if found then the next word should be a method name for that java file.

i followed this:

Quote:

Access modifier--- Return value-- Method Name (parameter...)
or,
Return Value--Method Name()

String target = "(";
String[] returnValue={"String", "int", "double", "void", "char", "long", "float" };
 Map<String, File> names = new HashMap<String, File>();
 
try{ 
File directory = new File("C:/JavaFiles"); // where all java files are gathered 
File filelist[]= directory.listFiles();

   for (File f: filelist) {
    
            FileReader fr = new FileReader (f);    
            BufferedReader reader = new BufferedReader (fr);

                while (reader.ready()){ 
                result=reader.readLine();
                                
                   if (result.indexOf(target)!= -1 ){ 
                  String line = result.substring(0, result.indexOf(target));
                            
                       Scanner scan=new Scanner(line);            
                       for (int i=0; i<returnValue.length; i++) {
                       word=scan.findWithinHorizon(returnValue[i], 100);
                                
                                if(word!=null) {
               methodName=scan.next()+scan.findWithinHorizon("", 0);
                                names.put(methodName, f);
                for (String found: names.keySet()){
          File file = names.get(found);
        System.out.println(found+"\t"+"FileName: "+file.getName());
            }
                                    
                               }// end 2nd if
                            }// end 2nd for
                        }//end 1st if
                   }//end while    
        }//end 1st for
}//end try


catch(Exception e){e.printStackTrace(); }
