How can I instantiate an array of objects via reflection? For example, I have a Class X, and I want to instantiate X[10].

You can use newInstance(Class componentType, int length) method of java.lang.reflect.Array class to instantiate an array of objects. For example,

X array[] = (X [])Array.newInstance(X.class, 10);

will have the same effect as:

X array[] = new X[10];

Primitive arrays (for example an array of int) can also be instantiated similarly:

int array[] = (int [])Array.newInstance(int.class, 10);

will have the same effect as

int array[] = new int[10];
