[問題] java寫猜數字遊戲(幾A幾B那種)
老師在上課有講解了以下的部分
但說得很快 >"<
要我們說明程式碼及修改以下程式碼
Number Guess Game.java 部分的上色處 for的地方
來完成完整版的4位數猜數字遊戲
1. 可由使用者選擇所欲猜測的數字有幾位
2. 使用者可查詢過去所輸入的猜測
3. 電腦可提供提示 (例如 : 1A2B)
4. 遊戲排行榜
而這個猜數字的遊戲 包含了 Number Guess Game.java / Answer.java
及Main.java三個部分
(主要是修改Number Guess Game.java 部分及在執行時能印出步驟說明
例如: 你猜錯了 繼續加油 )
