New try out-can anyone explain so that I learn this?

Question

Hi all!
I posted last night a tryout for a form that could be used in dogcompetitions. I am a total noob here and have tried to learn java from "head first java "so I would appreciate if someone could explain how I make this little application actually save and put out my filled in data.

         TextField t1,t2,t3,t4,t5,t6,t7;
         Label l1,l2,l3,l5,l6;
         Button anml,ngra,nsta;
         formular()

            addWindowListener(new WindowAdapter(){
                     public void windowClosing(WindowEvent we){
                                              System.exit(1);}});
                     setVisible(true);
                public void actionPerformed(ActionEvent ae) {
                              if(ae.getSource()==anml) {
                              File f=new File("c:/text.txt");
                             try{

                                      String s3=t3.getText();
                                      String s5=t5.getText();
                                      byte b1[]=s1.getBytes();
                                      byte b2[]=s2.getBytes();
                                      byte b3[]=s3.getBytes();
                                      byte b5[]=s5.getBytes();
                                      fos.write(b1);
                                      fos.write(b2);
                                      fos.write(b3);
                                      fos.write(b5);
                                      fos.flush();
                                      fos.close();
                                      catch(Exception e){ }
                                if(ae.getSource()==ngra) {
                                System.exit(1);}
                                    if(ae.getSource()==nsta) {
                                    setVisible(false);
                                                        new formular();
                                        public static void main ( String args[] ) {
                                                  new formular();
                                    }What I want is to be able to save this input data in a list and then get it all again (If say 3 people puts their dog in the application) I want the program to give me back all 3 of the dog applications.

Answer 1

The jump however in response to the above to replies, between AWT and Swing is not huge. many similiar names given to the thier classes. You should go have a look at swing, it will change your life. About the bad code some pointers are...
1) Neat nesting applies to where closing and opening braces of blocks are placed.
2) Dont nest to deep. To reasons apply here.... you need to make yr classes or code block do less. IOW building a whole house should not go in 1 class but should rather have many phases like layBricks() buildRoof() etc and the other reason being the ease of reading which is what you will be critisized most for here.
