java.lang.Class object for array

[Bupjae Lee]

For example, if I have Class object from array, I can get the component type of that array by writing this code:

Class<?> clazz=Object[].class;
Class<?> component=clazz.getComponentType(); // It returns Object.class

The problem is, if I have some Class object, how can I make the Class object for array which component type is given.

For example, how can I make Object[].class from Object.class?

The Array class offers methods to do this.

Then, can I write like this?

Class<?> clazz=Object.class;
Class<?> arrayClazz=Array.newInstance(clazz, 0).getClass();

It doesn't seem to "straight" method, but I'll try it. Thanks.

Oh, I misunderstood. I don't see why you'd want to do that, but yes that should work.

Yes, but remember that what it will return is the array's class - ie, for:
Array.newInstance(int.class, 0).getClass()
it will return int[].class.

As long as that's what you want, you should be fine.
