Java Problem

I'M POSTING IN THIS SECTION BECAUSE JAVA SECTION IS DEAD, PLEASE DONT MOVE IT

I'm trying to create a window with one Label, one TextField and one Button... But I have a problem, nothing shows up unless I resize the window manually (with my mouse), or if I remove the TextField it will work...

Main file:

Code:

import javax.swing.JLabel;
import javax.swing.JButton;
import javax.swing.JTextField;

public class App  {


	public static void main(String[] args) {
    
    	janela nova = new janela("Window Title",800,200);
    	JLabel txt = new JLabel("Please tell us your name:");
    	JButton btn = new JButton("Ok");
    	JTextField nameTxt = new JTextField("enter text here",30);
    	nova.add(txt);
    	nova.add(nameTxt);
    	nova.add(btn);

    
    	
    }
}

janela file:

Code:

import java.awt.FlowLayout;
import javax.swing.JFrame;

public class janela extends JFrame  {
	private static final long serialVersionUID = 1L;
   
	public janela(String title,int width,int height){
		super(title);
		setLayout(new FlowLayout());
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setSize(width,height);
		setVisible(true);
	}

	
}

Help a noob out please

After a quick glance at your code, I sort of realized this.

You aren't defining where to put the things, right?

nova.add(txt);

Are you even defining where to place it?

I'm using the FlowLayout, it adds it automaticly, if you run it and then resize the window with your mouse everything will show up, or if you just dont add the textField everything will be in its place... strange thing..

Nope, if that was the problem, nothing i've ever done would show up....
Anyone help?

Where are the pros? Like @Jason , @NextGen xD and the others pros i used to see there xD

Here you go

Code:

import javax.swing.JLabel;
import javax.swing.JButton;
import javax.swing.JTextField;

public class App  {


	public static void main(String[] args) {
    
    	janela nova = new janela("Window Title",800,200);
    	JLabel txt = new JLabel("Please tell us your name:");
    	JButton btn = new JButton("Ok");
    	JTextField nameTxt = new JTextField("enter text here",30);
    	nova.add(txt);
    	nova.add(nameTxt);
    	nova.add(btn);
    	nova.validate();
    	
    }
}

I added nova.validate();.
