小弟想要在press［5］轉換英文介面
但不管我怎麼研究都無法執行成功
我試圖在default: Break之間
硬塞一個英文介面但都不成功 可能對資料結構不熟
Java新手求教。
不是來這求答案是來求知識

1F：推 icydream: 在英文介面中，若輸入的值<=5的話，就會離開迴圈 01/10 07:33
2F：推 icydream: 我的想法是新增一個boolean變數，預設是true，用來判斷 01/10 07:42
3F：→ icydream: 呈現介面，預設是中文介面。然後在選項的地方，使用這 01/10 07:42
4F：→ icydream: 個變數判斷呈現的是中/英文，在default裡把這個變數值設 01/10 07:42
5F：→ icydream: 為false 01/10 07:42
6F：→ HarryWen: If(select<=5) While(select<=5) 01/10 14:21
7F：→ HarryWen: Boolean status=true. ; System.out.println("status=" 01/10 14:23
8F：→ HarryWen: +status); 01/10 14:23
9F：→ HarryWen: 像這樣子嗎 01/10 14:24
