问题描述
在我使用任何编程语言的 1 个月经验中,我假设 switch case 条件将接受括号中的任何内容作为布尔检查 thingamajig, IE这些:
In the 1 month experience I've had with any programming language, I've assumed that switch case conditions would accept anything in the parenthesis as a boolean checking thingamajig, ie these:
|| && < >
明白我的意思吗?
类似
char someChar = 'w'; switch (someChar) { case ('W' ||'w'): System.out.println ("W or w"); }
可悲的是,这种方式似乎并不奏效.我不能在开关盒中进行布尔检查.
Sadly, doesn't seem to work that way. I can't have boolean checking in switch case.
有办法解决吗?
顺便说一句,如果我听起来令人困惑,非常抱歉.我还不太清楚这种语言中所有内容的名称:X
任何答案表示赞赏
By the way, terribly sorry if I'm sounding confusing. I don't quite know the names for everything in this language yet :X
Any answers appreciated
推荐答案
对于这样的情况,您可以实现 OR:
You can achieve an OR for cases like this:
switch (someChsr) { case 'w': case 'W': // some code for 'w' or 'W' break; case 'x': // etc }
案例就像一个goto",多个 goto 可以共享同一行来开始执行.
Cases are like a "goto" and multiple gotos can share the same line to start execution.
