public class TinyWindow extends JFrame{

	static final long serialVersionUID = 123;
	
	public static void main(String[] args) {
		
		TinyWindow window = new TinyWindow();
		window.setVisible(true);
         
	
	}
	TinyWindow(){
		JPanel content = new JPanel();
		content.setLayout(new FlowLayout());
		
		JLabel greeting = new JLabel("We come in peace :))");
		content.add(greeting);
		
		setContentPane(greeting);
		pack();
