How to copy value of class to another?

I want to sort an array of classes.

So I need to exchange the value of class in this way:

tmp = a;
a = b;
b = tmp;

However, I know that this is not copying the value of class.

Could anyone tell me how to copy the value of class?

You would have to copy the value of all of the class' fields.

But take a look at Arrays.sort(). With that method you can sort an
array of anything. You will need to look at Comparator too.

Class a = Wombat.class;
Class b = something.getClass();
Class temp = a;
a = b;
b = temp;
