How do I split a list to stringS (plural)-CodePudding

I have a list of strings of dynamic length: List<String> processInstanceIds = new ArrayList<>();

I have a function that doesn't accept a list as parameter, but requires one to several individual strings:

function

How can I transform this list of dynamic length to a dynamic amount of strings and pass them to the function?

myfunction(String.join(", ", theList)) did not work as it would create one string instead of several.

CodePudding user response：

Java varargs creates a method array parameter. Try something like this:

String[] blam = yourList.toArray(processInstanceIds);

kapow.myFunction(blam);

Probably, you could try something like below

processInstanceIds.toArray(new String[processInstanceIds.size()])
