manipulating jLabel from main method in netbeans

I am trying to change the text inside a jLabel from the main method, the reason for this is because there are conditions that I need to meet for the change to happen and it is not trigger based.

Code:

public class TheMain extends javax.swing.JFrame {


    public TheMain() {
        initComponents();
    }

public void changeLabel1(){
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
               jLabel1.setText("looo");
            }
        });
    }

    public void changeLabel2(){
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
               jLabel2.setText("looo");
            }
        });

    }

    public static void main(String args[]) {
         TheMain some = new TheMain();
         if(condition){
             some.changeLabel1();
         }else{
             some.changeLabel2();
         }
    }

}

I tried printing some stuff inside changelabel1 and changelabel2 just to check if they are successfully called and it did print but I'm guessing it is not possible to implement the UI changes inside them, or am I mistaken?

     if(condition){
         some.changeLabel1();
     }else{
         some.changeLabel2();
     }

The above logice needs to be defined in TheMain class because that is where the label variables will be defined.

The main() method is just used to create the GUI. There should be no application logic in the main() method.
