// We need the LeJOS class that deals with the EV3 Buttons.
// One possibility is to use the NXT Button abstraction defined by:
// import lejos.hardware.Button;
//
// In this version we display the message "Hello World", but then pause
// (to allow the text to be visible) until the user presses a button.
// We use the LCD classes to display text on the LCD screen, as this
// is better than simply using System.out.println

import lejos.hardware.lcd.LCD;
import lejos.hardware.Button;

public class HelloWorld {

	public static void main(String[] args) {

		LCD.clear();
		LCD.drawString("Hello World", 3, 2);
	    System.out.println("Writing into a file");
				
        Button.waitForAnyPress();
        
		LCD.clear();		
		LCD.drawString("Goodbye", 6, 4);
        Button.waitForAnyPress();
	}
