swing - Creating an Open Function in Java using JFIleChooser -


hi having issues completetly understanding feature of notepad. want user ot search .txt file desire in directory , able open it. remember notepad file must readeable , writable. created simple open stuck in fact keep getting red in br = new bufferedreader(new filereader(open));, on new filereader(open)); part. how can fix this? appreciated. public void actionperformed (actionevent event) {

    if(event.getsource() == this.newfile){         this.textarea.settext("");      }else if(event.getsource() == this.openfile){         jfilechooser open = new jfilechooser();         int option = open.showopendialog(this);         filereader fr;         bufferedreader br;          if(option == jfilechooser.approve_option){             try{                 br = new bufferedreader(new filereader(open));                  //while(){                  //}              }catch(exception ex){                 system.out.println("");             }         }     } }

jfilechooser not file, can not used parameter filereader, instead, need selected file chooser...

file choosenone = open.getselectedfile(); br = new bufferedreader(new filereader(choosenone ));

there options available make life little easier, filters.
