只要我能得到，这就是您想要的水。

Object[] colours = {"Blue", "Red", "Black", "White"};

int n = JOptionPane.showOptionDialog(null,
    "Which colour do you like?",
    "Choose a colour",
    JOptionPane.DEFAULT_OPTION,
    JOptionPane.QUESTION_MESSAGE,
    null,
    colours,
    colours[0]);

System.out.println("The users likes " + colours[n]);
