标题[问题] 自制atm问题
时间Sun Jan 10 00:13:33 2016
小弟想要在press［5］转换英文介面
但不管我怎麽研究都无法执行成功
我试图在default: Break之间
硬塞一个英文介面但都不成功 可能对资料结构不熟
Java新手求教。
不是来这求答案是来求知识

1F：推 icydream: 在英文介面中，若输入的值<=5的话，就会离开回圈 01/10 07:33
2F：推 icydream: 我的想法是新增一个boolean变数，预设是true，用来判断 01/10 07:42
3F：→ icydream: 呈现介面，预设是中文介面。然後在选项的地方，使用这 01/10 07:42
4F：→ icydream: 个变数判断呈现的是中/英文，在default里把这个变数值设 01/10 07:42
5F：→ icydream: 为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: 像这样子吗 01/10 14:24
