import java.awt.datatransfer.DataFlavor;

public static String readClipboard() {
    return (String) Toolkit.getDefaultToolkit().getSystemClipboard().getData(DataFlavor.stringFlavor);
}

public class SystemClipboardAccess {

    public static void main(String args[]) throws Exception {
        // Create a Clipboard object using getSystemClipboard() method
        Clipboard c = Toolkit.getDefaultToolkit().getSystemClipboard();

        // Get data stored in the clipboard that is in the form of a string (text)
        System.out.println(c.getData(DataFlavor.stringFlavor));
    }
}
