Copy, Paste and Cut an Array of integers in java using Clipboard?

I was able to develop, here is the code below:

public class CopiarColarArray {

public void copiar(){
    int[] data = new int[]{1,2,3,9872,5374,57};
    MinhaClasseSelection selection = new MinhaClasseSelection(data);
    Clipboard cb = Toolkit.getDefaultToolkit().getSystemClipboard();
    cb.setContents(selection, selection);      
}

public void recortar(){
    int[] data = new int[]{1,2,3};
    MinhaClasseSelection selection = new MinhaClasseSelection(data);
    Clipboard cb = Toolkit.getDefaultToolkit().getSystemClipboard();
    cb.setContents(selection, selection);      
    data = new int[]{};
}

public void colar(){
    Clipboard cb = Toolkit.getDefaultToolkit().getSystemClipboard();
    try {
        Transferable t = cb.getContents(this);
        if(t.isDataFlavorSupported(MinhaClasseSelection.ARRAY_INT_DATA_FLAVOR)){
            int[] data = (int[])(t.getTransferData(MinhaClasseSelection.ARRAY_INT_DATA_FLAVOR));
            for (int i = 0; i <data.length; i++) {
                System.out.println("Array: "+data[i]);
            }
        }                
    } catch (UnsupportedFlavorException ex) {
        Logger.getLogger(CopiarColarArray.class.getName()).log(Level.SEVERE, null, ex);
    } catch (IOException ex) {
        Logger.getLogger(CopiarColarArray.class.getName()).log(Level.SEVERE, null, ex);
    }
}

/* Minha classe perfonalizada do Selection */
public static class MinhaClasseSelection implements Transferable, ClipboardOwner {
    private int[] intData;

    public final static DataFlavor ARRAY_INT_DATA_FLAVOR = new DataFlavor(int[].class, "Array int");
    public final static DataFlavor[] flavors ={ARRAY_INT_DATA_FLAVOR};

    public MinhaClasseSelection(int[] data){
        intData = data;
    }

    @Override
    public DataFlavor[] getTransferDataFlavors() {
        return flavors;
    }

    @Override
    public boolean isDataFlavorSupported(DataFlavor df) {
        for (int i = 0; i < flavors.length; i++) {
            if (df.equals(flavors[i])){
                return true;
            }
        }

        return false;
    }

    @Override
    public Object getTransferData(DataFlavor df) throws UnsupportedFlavorException, IOException {
        if (df.equals(ARRAY_INT_DATA_FLAVOR)){
            return intData;
        }
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

    @Override
    public void lostOwnership(Clipboard clpbrd, Transferable t) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

  }
}
