Hi,

I got no idea how to get the type in Array.

E.g

if(parameters.isPrimitive())
{
/* Code Goes here for Primitive */

}
else if ( parameters.isArray() )
{
/*
* Then, I need to find out what types are in that array
* I'm stucked here.
*/
}

Can anyone help me with this?

Regards;
Stephen

I removed the duplicate ... you may want to use the [ code ][ /code ] tags next time you post a snippet of code ... it makes it a lot easier for others to read.

if the array is the array of some objects, as far as i know if you are looking for the name of the class from which the object was instantiated you could simply use this: some_array[0].getClass().getName()..you can look those methods up in javadoc online at: http://java.sun.com/j2se/1.3/docs/api/index.html..hope this helps.

some_array[0].getClass().getName() --
Not like that I don't even know what is the length of the array. I only know the parameter is array. and getName() will be OK if the array are of Objects type and getName() will return something weird if it is primitive.

But, I've found a way.
getComponentType() returns the true type. If short, it will return short.

The easiest way would be to use instanceof.
If you want know the type of the array, do like this:

myObject myArray[] = new myObject[10];
if (myArray instanceof myObject[]) {
....

If you need to find out the type of one element in the array:.

Animal animals[] = new animals[10];
animals[0] = new Cat();
animals[1] = new Dog();

if (animals[0] instanceof Cat) {
..
