How to load a text file in a Java swings application

Question

hi,
I am trying to retrieve a Java code(or say any text from an existing file) and display it in a swing application.
I am not able to do so.
Please help me.

Answer 1

public String readFile(File f){
          try {
               BufferedReader read = new BufferedReader(new FileReader(f));
               String line = read.readLine();
               String total = "";
               while(line != null){
          //          System.out.println(line);
                    total += line;
                    line = read.readLine();
               read.close();
               return total;
          } catch (Exception e){
               e.printStackTrace();
          return "";
     }that will read a file into a string, i hope you can figure out the rest
