Question

I have a method which will return two strings in an array, split(str, ":", 2) to be precise.

Is there a quicker way in java to assign the two values in the array to string variables than

String[] strings = str.split(":", 2);
String string1 = strings[0];
String string2 = strings[1];

For example is there a syntax like

String<string1, string2> = str.split(":", 2);

Thanks in advance.

No, there is no such syntax in Java.

However, some other languages have such syntax. Examples include Python’s tuple unpacking, and pattern matching in many functional languages. For example, in Python you can write

 string1, string2 = text.split(':', 2)
 # Use string1 and string2

or in F# you can write

 match text.Split([| ':' |], 2) with
 | [string1, string2] -> (* Some code that uses string1 and string2 *)
 | _ -> (* Throw an exception or otherwise handle the case of text having no colon *)
