我真的不明白的問題。你有所有你需要的方法。 無論如何，我會盡量給你一些提示。首先，如果JTextField用於創建新地址，並且不更新其中一個現有的，那麼靜態數組可能不是正確的選擇。你應該使用ArrayList代替：

ArrayList<Address> p = new ArrayList<Address>(); 

然後簡單地檢索來自JTextField中的數據，並構建另一個地址對象：

Address newAddress = new Address(HouseNumber.getText(), 
           StreetName.getText(), 
           Town.getText(), 
           Postcode.getText()); 
p.add(newAddress); 

這是否足以解決你的疑惑？
