JTextArea not visible

Here is my code. I have tried to keep it very simple.

public class GUI_ADV extends JFrame {
    public static void main(String[] args) {
        NewClass abc = new NewClass();
        abc.setLayout(new FlowLayout());
        abc.setSize(250,450);
        abc.setDefaultCloseOperation(EXIT_ON_CLOSE);
        abc.setVisible(true);
    }
}

And the other class:

public class NewClass extends JFrame {
    public void NewClass() {
        JPanel cp = new JPanel();
        JTextArea ta = new JTextArea("text",5, 20);
        JScrollPane jp = new JScrollPane( ta );  
        cp.add( jp );
        //message.setLineWrap(true);
        //message.setWrapStyleWord(true);
        JScrollPane scroll = new JScrollPane(ta,5,5);
        //setLayout(new FlowLayout());
        //because it is done in main class
        cp.add(scroll);
        add(cp);
        //setVisible(true);    
        //Its done in main class
    } 
}

It is not working. It comes blank with the title bar and the empty window.

The constructor should not be void or return any thing, else it will be considered like a method and not a constructor :

public void NewClass() {
//      ^^-------------------------mistake

Instead you have to use:

public NewClass() {
