Java swing JLabel没有显示

Question

在退出我的比赛时,我想展示一个"退出".exitscreen.gif在文件夹中,工作正常,但由于某种原因,只有空白框显示:

JPanel finishPanel = new JPanel();
JLabel finishLabel = new JLabel(new ImageIcon("welcomescreen.gif"));
finishPanel.add(finishLabel);
finishLabel.setSize(11 * 35, 11 * 35);
finishPanel.setPreferredSize(finishLabel.getSize());
this.frame.setVisible(false);
JFrame exitFrame = new JFrame("Thanks for playing");
exitFrame.getContentPane().add(finishPanel);
exitFrame.setLocationRelativeTo(null);
exitFrame.pack();
exitFrame.setVisible(true);
finishLabel.setVisible(true);

this.frame只是我不再需要的另一个JFrame.

Answer 1

你的代码看起来很好,甚至对我来说都很好.我想问题是welcome.gif文件的位置.

即使我先得到一个空白屏幕,但我将welcome.gif移动到项目根目录下的正确位置.
