Перерисовка изображения при нажатии JButton

Хочу, чтобы при нажатии кнопки "UP" аймэдж "gena" стирался и появлялся в новом месте - то есть x = x + 100. Но при нажатии кнопки ничего не происходит. Вот код:

import java.awt.*;
import java.awt.event.ActionEvent;

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.util.List;
import javax.imageio.ImageIO;
import javax.swing.*;

}
