Groovy收集字符串

Question

When I collect over a String I was expecting that it would be of type char , but it is java.lang.String . So why is this and how can I collect all characters of a String?

Answer 1

You can do something like this...

someString.collect { 
    def c = it as char
    // carry on...
}

Or...

someString.chars.collect {
    // it will be a char
    // carry on...
}

Answer 2

In Groovy, a single character is also a String. In order to get each String as a Character use as:

"testString".collect { it as char }
