Casting to a java object in Mozilla Rhino

Question

I'm wondering is there a way of casting a Java object in Rhino? I would usually do this in Java by doing the following:

List<Object[]> mylist = myServiceClass.getList(id);
for (Object[] object : myList) {

  Apple a = (Apple) object[0];
  // do something    
}

But in Rhino, I'm not sure. Is there a way to do this?

I've tried:

apple = myList.get(i)

And:

apple = (Packages.com.package.fruits.Apple) myList.get(i);

I keep getting the error

Java class "[Ljava.lang.Object;" has no public instance field or method named "getColour" when trying to access the apple object.

Answer 1

You don't need to cast in javascript. But you need to call the method on the correct object. The error message states that you call the method on an Object[] (The [ before L gives that away).

To get the first object from Object[] before you call getColour() on it

myList.get(i)[0].getColour()
