我在哪里输入java程序的图像输入?

我一直在学习图形教程,在一个程序中,作者使用图像制作纹理颜料。我复制了他的代码,但我不知道在哪里实际放置图像供它阅读。我已经尝试在eclipse中创建一个资源文件夹并将其设置为源文件夹构建路径,但这不起作用。代码如下:

编辑: 好吧,我发现它正在从课堂的来源拍摄图像。但是,假设我想从我的桌面或硬盘驱动器上的其他位置提取图像,我该怎么做?

class Surface extends JPanel {

    private BufferedImage slate;
    private BufferedImage java;
    private BufferedImage pane;
    private TexturePaint slatetp;
    private TexturePaint javatp;
    private TexturePaint panetp;

    public Surface() {

        loadImages();
    }

    private void loadImages() {

        try {

            slate = ImageIO.read(new File("slate.png"));
            java = ImageIO.read(new File("java.png"));
            pane = ImageIO.read(new File("pane.png"));



 } catch (IOException ex) {

        Logger.getLogger(Surface.class.getName()).log(
                Level.SEVERE, null, ex);
    }
}

private void doDrawing(Graphics g) {

    Graphics2D g2d = (Graphics2D) g.create();

    slatetp = new TexturePaint(slate, new Rectangle(0, 0, 90, 60));
    javatp = new TexturePaint(java, new Rectangle(0, 0, 90, 60));
    panetp = new TexturePaint(pane, new Rectangle(0, 0, 90, 60));

    g2d.setPaint(slatetp);
    g2d.fillRect(10, 15, 90, 60);

    g2d.setPaint(javatp);
    g2d.fillRect(130, 15, 90, 60);

    g2d.setPaint(panetp);
    g2d.fillRect(250, 15, 90, 60);

    g2d.dispose();
}

@Override
public void paintComponent(Graphics g) {

    super.paintComponent(g);
    doDrawing(g);
}

}

This可能会有所帮助。
或者只使用绝对路径来存档。 linux:/ home / user / ... widndows:C:/ Users /..
