主要就是操作Clipboard类
放出来，需要就看看了

import java.awt.datatransfer.DataFlavor;
import java.awt.datatransfer.Transferable;
import java.awt.datatransfer.UnsupportedFlavorException;
import java.io.File;
import java.io.IOException;
import java.util.ArrayList;

	}
}

	}

	@Override

	{
		for (int i = 0; i < dataFlavors.length; i++) {

				return true;

	}
