will help you Don't forget you're not passing variables... You're writing javascript code
So, you have to make your array rendering nicely for Javascript
code :
var jsArray = [%{javaArray.eachWithIndex{it,idx->
                 }%
                 ${it}${(idx<javaArray.size()-1)?",":""}
                 %{
                 }
                 }%]

MyClass {

     private Rectangle rectArray[] = new Rectangle[9];

     MyClass() {

this will help I am looking for declaring the type of 2D array that can hold only 3 distinct values in the below code. , For three values, an enum is very compelling;
code :
enum ExampleEnum {
    ONE, TWO, THREE;

    @Override
    public String toString() {
        switch (this) {
        case ONE:
            return "One";
        case TWO:
            return "Two";
        default:
            return "Three";
        }
    }
}
ExampleEnum[][] twoDimArray = new ExampleEnum[3][3];
System.out.println(Arrays.deepToString(twoDimArray));

this will help In Java, all array elements are automatically initialized to the default value. For primitive numerical types, that's 0 or 0.0. For booleans, that's false. For objects, that's null.
In other languages such as C++, the values in an uninitialized array are undefined. Some compilers may initialize to 0/null similarly for security, and it's very bad practice to rely on this. However, this behavior is well defined in Java and so it's perfectly okay to create a primitive array and trust that the values are 0.
