Pass an Array to a Constructor without declaring it?

Question

In processing, I have defined the following class:

class SomeClass {
    SomeClass(int[] someArray) {
        println(someArray);
    }
}

You still need to define it somehow before you send it in... Try this:

SomeClass myVar = new SomeClass(new int [] {
    12, 10
});

or you could try some of Java's syntactic sugar...

class SomeClass {
    SomeClass(int... someArray) {
        println(someArray);
    }
}
SomeClass myVar = new SomeClass(12, 10);

which will introduce some restrictions to your coding style... For example you can do this: (special syntax as the last element)

class SomeClass {
    SomeClass(String someString, float someFloat, int... someArray) {
        println(someString);
        println(someFloat);
        println(someArray);
    }
}
SomeClass myVar = new SomeClass("lol",3.14, 12, 10);

but not this: (special syntax not as the last element)

class SomeClass {
    SomeClass(String someString, int... someArray, float someFloat) {
        println(someString);
        println(someFloat);
        println(someArray);
    }
}
SomeClass myVar = new SomeClass("lol", 12, 10,3.14);

Arrays are fun!!
