Reflection: Extracting object from an array of unknown type and unknown dimension

I am trying to use Java Reflection APIs for extracting all member items from an array of unknown type and unknown dimension?? Here are some possible inputs:
int [] arr; ---> trying to extract individual item from the int array
ABC [] arr; ---> trying to extract indidvual ABC object from the ABC array
float [] [] [] arr; ---> trying to extract individual float from a 3D float array
ABC [] [] [] arr; ----> trying to extract individual ABC object from a 3D ABC array

Any ideas??

You don't need reflection.
Consider the object you don't know its type is arrObj, now check following snippet

		if(arrObj.getClass().isArray()){
			if(int.class.equals(arrObj.getClass().getComponentType())){
				int[] realArray = (int[]) arrObj;
				for(int i = 0; i < realArray.length; ++i){
					//handle array
				}
			}else if (ABC.class.equals(arrObj.getClass().getComponentType())){
				ABC[] abc = (ABC[])arrObj; 
				for(int i = 0; i < realArray.length; ++i){
					//handle array
				}
			}
		}

for multi-dimension arrays you can check if getConponentType().isArray() is true

How do you handle arrays with *unknown* type and *unknown* dimension??

if you don't know the type you can always cast it to Object or Object[] and then invoke your desired method if you know the name of method

if(arrObj.getClass().isArray()){

    Object[] array = (Object[])arrObj;
    if(array.getClass().getComponentType().isArray(){
       for(Object obj : array){
          Object[] secondDimension = (Object[]) obj
          //.... 
       }
    }
}
