如何做在Java剪切複製粘貼

Question

我想要一個Java程序，可以訪問剪貼板執行功能，如剪切，複製和粘貼。如果有人願意幫我提供一個示例代碼，這將非常有幫助... 謝謝！

Answer 1

這裏是字符串複製爲JDK 7+（JavaFX的2）的一個工作示例：

public String pasteFromClipboard() { 
    return Clipboard.getSystemClipboard().getString(); 
} 

public void copyToClipboard(String text) { 
    HashMap<DataFormat, Object> map = new HashMap<DataFormat, Object>(); 
    map.put(DataFormat.PLAIN_TEXT, text); 
    Clipboard.getSystemClipboard().setContent(map); 
} 

JavaDoc for Clipboard。

Answer 2

 /** 
    * get string from Clipboard 
    */ 
    public static String getSysClipboardText() { 
     String ret = ""; 
     Clipboard sysClip = Toolkit.getDefaultToolkit().getSystemClipboard(); 

     Transferable clipTf = sysClip.getContents(null); 

     if (clipTf != null) { 

      if (clipTf.isDataFlavorSupported(DataFlavor.stringFlavor)) { 
       try { 
        ret = (String) clipTf 
          .getTransferData(DataFlavor.stringFlavor); 
       } catch (Exception e) { 
        e.printStackTrace(); 
       } 
      } 
     } 

     return ret; 
    } 

    /** 
    * put string into Clipboard 
    */ 
    public static void setSysClipboardText(String writeMe) { 
     Clipboard clip = Toolkit.getDefaultToolkit().getSystemClipboard(); 
     Transferable tText = new StringSelection(writeMe); 
     clip.setContents(tText, null); 
    } 

    /** 
    * get image from Clipboard 
    */ 
    public static Image getImageFromClipboard() throws Exception { 
     Clipboard sysc = Toolkit.getDefaultToolkit().getSystemClipboard(); 
     Transferable cc = sysc.getContents(null); 
     if (cc == null) 
      return null; 
     else if (cc.isDataFlavorSupported(DataFlavor.imageFlavor)) 
      return (Image) cc.getTransferData(DataFlavor.imageFlavor); 
     return null; 
    } 

    /** 
    * put iamge into Clipboard 
    */ 
    public static void setClipboardImage(final Image image) { 
     Transferable trans = new Transferable() { 
      public DataFlavor[] getTransferDataFlavors() { 
       return new DataFlavor[] { DataFlavor.imageFlavor }; 
      } 

      public boolean isDataFlavorSupported(DataFlavor flavor) { 
       return DataFlavor.imageFlavor.equals(flavor); 
      } 

      public Object getTransferData(DataFlavor flavor) 
        throws UnsupportedFlavorException, IOException { 
       if (isDataFlavorSupported(flavor)) 
        return image; 
       throw new UnsupportedFlavorException(flavor); 
      } 

     }; 
     Toolkit.getDefaultToolkit().getSystemClipboard().setContents(trans, 
       null); 
    } 

，如果你要處理的文件或文件夾，你可以嘗試

copyFile(srcPath, destDir, true/**overwriteExistFile*/);  

copyDirectory(srcPath, destDir, true/**overwriteExistDir*/);
