Learn about default values in Python, how to set them in functions, and their importance in programming.
In that case, have an empty default or else it is impossible to know if you meant to handle all cases: 如果就是没有默认动作,你只想处理特殊case时应该怎么做呢?这种情况下,保留一个空的默认处理,否则不可能知道你是否意图处理所有case。 void f2(E x) { switch (x) { case a: do_something()...

Default条件(有时也称为default语句)通常用于switch语句中,用于处理所有未匹配到其他case的情况。在groovy脚本中,可以使用switch语句来实现多重条件分支,具体语法如下: 代码语言:txt 复制 switch (expression) { case value1: // 如果expression等于value1,执行此处代码 break; case value2: // 如果expression等于value...
③break,可以使用在switch-case结构中,表示一旦执行此关键字,就跳出switch-case结构。 ④switch结构中的表达式,只能是如下6种数据类型之一:byte 、short、char、int、枚举类型(jdk5.0新增)、String类型(jdk7.0新增)。 ⑤case后只能声明常量,不可以是范围。
