如何处理多个条件？ [英] How to do a case with multiple conditions?

问题描述

在我使用任何编程语言的1个月经验中，我假设开关 案例条件将接受括号中的任何内容作为布尔检查thingamajig，即
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:

|| && < >

知道我的意思吗？

某事喜欢

char someChar = 'w';
switch (someChar) {
case ('W' ||'w'):
    System.out.println ("W or w");
}

可悲的是，似乎没有这种方式。我不能在switch case中进行布尔检查。

Sadly, doesn't seem to work that way. I can't have boolean checking in switch case.

有没有办法绕过它？

顺便说一句，如果我听起来很混乱，非常抱歉。我还不太清楚这种语言的所有名称：X

任何答案都赞赏

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

对于这样的情况你可以实现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和多个gotos可以共享同一行开始执行。

Cases are like a "goto" and multiple gotos can share the same line to start execution.
