What is the order running of the class / method in main [Java]

Question

Here is the code:

public static void main (String [] args) {
     new program1 () ;
     System.out.println("123Test") ;
}

public class program1 {
     public program1 () {
          abc () ;
     }
}

In the above case, 123Test will be printed when the program1 is running. What I want to ask is that how to address make 123Test print out until the program1 has been finished?

Somethings need to add is that in abc(), there will be a GUI, what I want to do is making a shutdown button. When someone press the button, the program1 will shutdown immediately like using frame.dispose(). Since I want to separate each JFrame into different classes, is there any ways to perform it better in the main? For example, I have program1 (), program2 (), program3 (), which represent different JFrame.

Like the comments mention, your question is extremely confusing, but I'll take a stab at it. I have no idea why you really need to have 5 separate classes for each JFrame, can't you simply make a method in your main class to do it?

private static void method1() {
    //initialize gui with
    Gui gui = new GUI();
    gui.setVisible(true);
    //do stuff        
    System.out.println("123Test");
}

If, for whatever reason, you really need to make a new Class, please follow coding conventions, as well as proper syntax. Your Class should be capitalized:

public static void main (String [] args) {
     Program1 program = new Program1();
}

public class Program1 {
    Program1() {
        //initialize gui here
        System.out.println("123Test") ;
    }
}

To be honest, it doesn't seem like you understand basic Java and I recommend doing tutorials of simpler programs first before messing around with JFrames.
