1.2 項目開發的碼雲地址：https://gitee.com/jbc1132/jbc1/blob/6c8f278bedba41d70802c3334c0afd08b42eafba/jbc1.java
1.3 選擇修改的程序代碼：
個人博客地址5：http://www.cnblogs.com/NianQiFeng ，源代碼：https://git.coding.net/qwx_hh/java-szys.git
1.4 碼雲提交記錄：
二、需求分析：
針對現有代碼的改進分析，新開發功能的分析。
現有代碼改進分析
目前就發現了兩個bug，一個是功能鍵“復習”，他會回到主頁面再次進行做題，功能鍵與實際內容不符，所以修改了功能鍵名稱為“繼續”。
另一個是他的正確率的計算有誤，第一次運行程序的時候，計算出來的正確率結果是正確的，當點擊了“繼續”並再次做題之後，他的正確題數rn會累加，導致正確率計算出錯，因此，我們在顯示正確率之後令“rn=0.0”，避免他的累加。
程序設計：針對新開發功能做設計，建議使用思維導圖。
原本打算用二叉樹來做隨機算術題的產生。但後來觀察了源代碼，如果要使用二叉樹的話要把他們的源代碼全部推翻重來，如此一來，將耗費大量的時間與精力，於是後來還是放棄了，選擇了一個較為簡單，而且契合惡源代碼的方法。
代碼如下：
