Is it possible to initialize a String[] array and pass it in a method in 1 line?

Question

Right now I have the following code:

String[] values = {str1, str2};
Utils.myMethod(values);

I would like to know if there is a way to do this all in one line. I've tried:

Utils.myMethod({str1, str2});

But that doesn't work. Thanks in advance.

You need to specify the type of the array explicitly. It is not inferred. Hence the following is valid,

Utils.myMethod(new String[] {str1, str2});

...and in case you want to work with Lists and want to initialize that list with values without much writing, use this: Utils.myMethod(Arrays.asList(new String[] {str1, str2}));

You can make it simple further: Utils.myMethod(Arrays.asList(str1, str2)); (with Java 1.5 or above since it is a vararg method)

Damnit, that's what i meant. C+P from OP's post made my skill look horrible. I don't deserve to be called a Nerd. You'll find me outside.

@Marithmu it's a lot more verbose than that. here's the required code: Utils.myMethod((String[]) Arrays.asList(str1, str2).toArray());

If you own the method in question, consider using the varargs syntax and declaring it like this:

void myMethod(String... args) {

Then, you can call it like this

Utils.myMethod(str1, str2);

Then let the compiler put the array together for you!

Well, you can always rewrite your method to use varargs. This way, you could write

Utils.myMethod(str1, str2);
