如何使用代碼在窗體上載圖像netbeans

Question

我正在用java編寫一個ID CARD處理應用程序，但是在上傳和顯示客戶端圖像的代碼中存在問題，我在爲圖片創建的標籤中顯示。下面的代碼唯一得到的是圖像路徑，但不是它自己的圖像。

這是我迄今嘗試過的代碼。

FileFilter ff = new FileNameExtensionFilter("images","jpeg"); 
     fc.addChoosableFileFilter(ff); 
     int open = fc.showOpenDialog(this); 

     if (open == javax.swing.JFileChooser.APPROVE_OPTION){ 

      java.io.File path = fc.getSelectedFile(); 

      String file_name = path.toString(); 

      pathe.setText(file_name); 

      java.io.File image = fc.getSelectedFile(); 

      ImageIcon photo = new ImageIcon(image.getAbsolutePath()); 

Answer 1

The code that does the magic is below 

     FileFilter ff = new FileNameExtensionFilter("images","jpeg"); 
     fc.addChoosableFileFilter(ff); 
     int open = fc.showOpenDialog(this); 

     if (open == javax.swing.JFileChooser.APPROVE_OPTION){ 

      java.io.File path = fc.getSelectedFile(); 

      String file_name = path.toString(); 

      pathe.setText(file_name); 

      BufferedImage bi; // bi is the object of the class BufferedImage 
// Now you use try and catch `enter code here` 

try{ 
bi = ImageIO.read(path); // path is your file or image path 
jlabel.setIcon(new ImageIcon(bi)); 
}catch(IOException e){ }
