how to separate this code in another class

[Jhovarie]

Hello every one i have a simple problem here i want to separate this code so that my code will become more easy to read. im using netbeans hear is my code

public class NewJFrame extends javax.swing.JFrame{
boolean logstart = false;
    public NewJFrame() throws IOException {
      initComponents();
// it is hard to develop application if the code are long so i want to separate this to another //external class plss help...
//Start here  ----------------------------------------
       setContentPane(jPanel1);
        try{
       int x = Integer.parseInt(new propAct().readSetting("locatefx"));
       int y = Integer.parseInt(new propAct().readSetting("locatefy"));
       String auto = new propAct().readSetting("auto");
       if(auto.equals("true")){
           automaticsignin.setSelected(true);
          String user =  new propAct().readSetting("pu")
         ,pass = new propAct().readSetting("wp");
          String usnam_decrypt = new cryptobrk().decrypt(user),
          pass_decrypt = new cryptobrk().decrypt(pass);
          System.out.println(usnam_decrypt);
          System.out.println(pass_decrypt);
       }
      String user =  new propAct().readSetting("pu");
       String usnam_decrypt = new cryptobrk().decrypt(user);
       jTextField1.setText(usnam_decrypt);
       setLocation(x,y);
        }catch(Exception e){
        new propAct().newSetting("pu", "");
        new propAct().newSetting("wp", "");
        }
//End here ----------------------------------------------------------------
    }
    @SuppressWarnings("unchecked")
  //Generated Code

Note i mean that i want to separate the code into another java file. from NewJFrame.java to initialize.java

So Do you have problem with this task? What can not you do?

[Jhovarie]

my code is working fine there is no error but i want only to separate it into another java file so that is will become more easier to read.

I clearly understand what you want make. You can use pattern MVC for this aim.
I looked on your code. It is very short. You have only 20 statement and it is all and I can excellent read this code.

I would suggest that this:

          String user =  new propAct().readSetting("pu")
         ,pass = new propAct().readSetting("wp");
          String usnam_decrypt = new cryptobrk().decrypt(user),
          pass_decrypt = new cryptobrk().decrypt(pass);

is less readable than this:

          String user =  new propAct().readSetting("pu");
          String pass = new propAct().readSetting("wp");
          String usnam_decrypt = new cryptobrk().decrypt(user);
          String pass_decrypt = new cryptobrk().decrypt(pass);

You also need to be a little more careful with indentation and style.But beyond that, I agree with Petr that you don't need to worry about length yet. You might at some point want a User class, but length of code is not the reason.

Just to be a little clearer:

Classes don't work like that. If your JFrame needs initialization code, you can't split that off into another class. You can perhaps split code into other methods within your class, and that's often a very good idea. Many of the variables within your constructor should probably be instance variables (fields) of your class. If you design things this way, you can move some of this code into a readProperties() method, for instance. As it is now, these variables you're assigning values to will disappear as soon as the constructor finishes executing.
