從一個JLabel

Question

獲得的ImageIcon絕對路徑通過使用：

jLabel1.getIcon().toString();

它僅返回參照對象 「javax.swing.ImageIcon@2982ccce」;

不是絕對路徑，那麼我該如何返回該圖標的絕對路徑？

例如：C:/File/imageicon.jpg

Answer 1

JLabel jLabel1 = new JLabel(); 
    jLabel1.setIcon(new ImageIcon(getClass().getResource("/lk/edu/ijse/examsimulator/img/Hand With Pen_36px.png"))); 
    if (jLabel1.getIcon() != null) { 

     Icon iconPath = jLabel1.getIcon(); 
     System.out.println(iconPath.toString()); 
     /* print  
     * file:/E:/Quick%20access/Documents/NetBeansProjects/ExamSimulator/ExmClientAdmin/build/classes/lk/edu/ijse/examsimulator/img/Hand%20With%20Pen_36px.png 
     */ 

     String absolutePath = iconPath.toString().replaceFirst("file:/", ""); 
     absolutePath = absolutePath.replaceAll("%20", " "); 
     System.out.println(absolutePath); 
     /* print 
     * 
     * E:/Quick access/Documents/NetBeansProjects/ExamSimulator/ExmClientAdmin/build/classes/lk/edu/ijse/examsimulator/img/Hand With Pen_36px.png 
     * 
     * it's my image absolute path */ 
    }
