java - ImageIcon 无法解析为类型

Question

我写了以下代码：

JLabel lblNewLabel_1 = new JLabel("");
Image img= new ImageIcon(this.getClass().getResource("/timeplanner11.jpg")).getImage();
lblNewLabel_1.setIcon(new ImageIcon(img));
lblNewLabel_1.setBounds(0, 0, 28, 30);
panel.add(lblNewLabel_1);

它显示错误：

ImageIcon cannot be resolved to a type

有人可以帮我纠正这个错误吗？

谢谢！！！

Answer 1

替换Image为ImageIcon

ImageIcon img= new ImageIcon(this.getClass().getResource("/timeplanner11.jpg")).getImage();

Answer 2

在类的顶部添加 javax.swing.ImageIcon 的导入，或者javax.swing.在每次调用之前添加，ImageIcon如下所示：

javax.swing.ImageIcon icon = new javax.swing.ImageIcon(this.getClass().getResource("/timeplanner11.jpg"));
lblNewLabel_1.setIcon(icon);

同样正如@MadProgrammer 所建议的，只需将其保留为 ImageIcon，无需创建图像，只需这样做：

JLabel lblNewLabel_1 = new JLabel("");
ImageIcon icon = new ImageIcon(this.getClass().getResource("/timeplanner11.jpg"));
lblNewLabel_1.setIcon(icon);
lblNewLabel_1.setBounds(0, 0, 28, 30);
panel.add(lblNewLabel_1);
