我的程序不起作用，我不知道爲什麼？

Question

這是我的一個學校項目的代碼，我必須做一個配料列表，以放在比薩餅上，也可以選擇一個大小。每一個都沒問題，當我醃香腸，火腿，加了1個意大利辣香腸，當我剔菠蘿時，加入了BlackOlives，洋蔥，GreenPepper 0.5美元。然而，當我剔額外奶酪增加像10.25或東西，也大小按鈕似乎不工作。請解釋這對我d：

Answer 1

你有這遍：

LargePizza = new JRadioButton("Large Pizza", false); 
ExtraCheese.addActionListener(new ActionListener() { 
^^^^^^^^^^^ 

對於配料的最後一堆，你總是把監聽到ExtraCheese，這意味着每個成分你選擇是要增加奶酪價格。
