import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class FlowLayoutText{
	public static void main(String args[]){
		if(args.length!=1){
			System.out.println("Usage:java FlowLayoutText NUMBER");
			System.exit(0);
		}
		String buttonString=args[0];
		int buttonNumber=Integer.parseInt(buttonString);
		ButtonFrame frame= new ButtonFrame(buttonNumber);
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.show();
	}
}
class ButtonFrame extends JFrame{
	public ButtonFrame(int buttonNumber){
		buttons=buttonNumber;
		setTitle("FlowLayoutText");
		setSize(WIDTH,HEIGHT);
		JPanel buttonPanel=new JPanel();
		for(int i=0;i<buttons;i++){
			JButton addButton=new JButton("add"+i);
			buttonPanel.add(addButton);
			
		}
		
		Container contentPane=getContentPane();
		contentPane.add(buttonPanel);
		
		}
