如何添加或決策執行圖像樹

Question

我想知道，如果你可以將圖像添加到一個決定，所以當用戶到達最後一個問題這樣，它顯示匹配什麼用戶已經輸入

圖像

我一直在想每一個結果，用戶將與特定的汽車品牌匹配，它會顯示一個隨機的汽車品牌的任何想法，我怎麼能做到這一點？

Answer 1

如果你想知道如何來顯示圖像，我得到這個代碼的Java的文檔（可以發現here）：

import java.awt.*; 
import java.awt.event.*; 
import java.awt.image.*; 
import java.io.*; 
import javax.imageio.*; 
import javax.swing.*; 

/** 
* This class demonstrates how to load an Image from an external file 
*/ 
public class LoadImageApp extends Component { 

    BufferedImage img; 

    public void paint(Graphics g) { 
     g.drawImage(img, 0, 0, null); 
    } 

    public LoadImageApp() { 
     try { 
      img = ImageIO.read(new File("strawberry.jpg")); 
     } catch (IOException e) { 
     } 

    } 

    public Dimension getPreferredSize() { 
     if (img == null) { 
      return new Dimension(100,100); 
     } else { 
      return new Dimension(img.getWidth(null), img.getHeight(null)); 
     } 
    } 

    public static void main(String[] args) { 

     JFrame f = new JFrame("Load Image Sample"); 

     f.addWindowListener(new WindowAdapter(){ 
       public void windowClosing(WindowEvent e) { 
        System.exit(0); 
       } 
      }); 

     f.add(new LoadImageApp()); 
     f.pack(); 
     f.setVisible(true); 
    } 
} 

您可以創建與圖像名稱的字符串變量，並改變它，這取決於節點用戶在樹中結束。希望這可以幫助你至少在正確的方向前進。
