向Java项目添加资源
我试图在我的JButton中添加一个图标,但我一直得到一个NullPointerException,这意味着找不到我指定的图像
我的课程和按钮都是远程刷新。png直接位于src文件夹中(类位于默认包中)。从昨晚开始,我一直在谷歌上搜索这个,无论我怎么尝试,我都无法加载资源
public class InfiltratorClient {
private MainWindow mw;
public static void main(String[] args) {
new InfiltratorClient();
}
public InfiltratorClient () {
mw = new MainWindow();
}
}
public class MainWindow extends JFrame {
private JPanel contentPane;
private InfiltratorClient n;
public MainWindow() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 450, 300);
this.setSize(650, 600);
setVisible(true);
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
setContentPane(contentPane);
contentPane.setLayout(null);
JButton btnNewButton = new JButton("New button");
btnNewButton.setBounds(258, 228, 140, 105);
contentPane.add(btnNewButton);
//In this Line i get the exception
ImageIcon icon = new ImageIcon(MainWindow.class.getResource("buttonremorerefresh.png"));
btnNewButton.setIcon(icon);
repaint();
revalidate();
}
}
