Groovy 条件语句_groovy if else

在groovy中支持如下 条件语句

1:if/else if/else

if ( ... ) {
    ...
} else if (...) {
    ...
} else {
    ...
}

2:switch / case

Groovy中的switch语句向后兼容Java代码

Switch supports the following kinds of comparisons:

• Class case values match if the switch value is an instance of the class

• Regular expression case values match if the toString() representation of the switch value matches the regex

• Collection case values match if the switch value is contained in the collection. This also includes ranges (since they are Lists)

• Closure case values match if the calling the closure returns a result which is true according to the Groovy truth

• If none of the above are used then the case value matches if the case value equals the switch value
