的ImageIcon不能被解析爲一個類型

Question

我寫了下面的代碼：

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); 

它顯示錯誤：

ImageIcon cannot be resolved to a type 

能有人幫我糾正這個錯誤？

謝謝!!!

Answer 1

在你班上名列前茅每次調用之前添加javax.swing.ImageIcon中導入或添加到javax.swing.像ImageIcon如此：

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

此外，通過@MadProgrammer的建議只是把它作爲一個ImageIcon，沒有必要製作圖片，只是這樣的：

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); 

Answer 2

更換Image與ImageIcon

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