我和一個合作伙伴一直在爲我們班級創作一款遊戲。雖然我們可以製作形狀，但我們無法加載精靈。我不確定所有這些代碼是否必要，但它似乎是必要的類，並且在這裏我們的代碼的任何其他幫助將不勝感激。Sprites not loading

public class BoardGraphics extends JPanel{
public BoardGraphics(){
initGraphics();
}
//Image Url's
String grassTS = "src/Resources/Sprites/GrassTile_1.png";
//Image objects
BufferedImage grassTI;
public void layTiles(Graphics g){
for(int i = 0; i < 21; i++){
for(int k = 0; k < 21; k++){
}
}
}
public void loadImage(String url, Image image){
try {
image = ImageIO.read(new File(url));
if(image != null){
System.out.println(url + ", has been loaded!");
}
}catch (IOException e){
e.printStackTrace();
}
}
public void initGraphics(){
setBackground(Color.WHITE);
setDoubleBuffered(true);
loadImage(grassTS, grassTI);
}
public void drawPlayer(Graphics g){
g.fillOval(5,5,32,32);
}
@Override
protected void paintComponent(Graphics g) {
super.paintComponent(g);
g.setColor(Color.BLACK);
g.drawImage(grassTI,21,21,null);
drawPlayer(g);
layTiles(g);
}
}
我的合作伙伴已經完成了大部分代碼，並且我對Java中的圖形化編程知之甚少。另外我試圖分開這兩個類。
