I'm using com.sun.codemodel for generating my classes.
I need to dynamically get array value depending on index argument.

So i have an invocation that suppose to return an array 

```
 JcodeModel model = new JCodeModel();
 JPackage jPackage = codeModel._package(packageName);
     .....
 JType personType = codeModel._ref(Person.class);
 jVar personObject = method.decl(personType, "person", JExpr._new(personType));
 personObject.invoke("getRoles");???

```

In this case getRoles() returns an array and i want to get an object at a specific index.
Something like this 

```
int index = 0;
Person person = new Person();
String role = person.getRoles()[index];

```

What should i do?
