Question

Is there a way of doing this in Java?

class A { ... }
class B { ... }

void method()
{
 Class[] array = {A,B,A,A};
 int i = 2;
 Object object = new array[i]();
}

and no, I don’t want to use any ifs or switches like below

if(i==0) object = new A();
else if(i==1) object = new B();
...

Answer 1

You would have to do something like this:

class A { ... }
class B { ... }
void method(){
    Class[] array = {A.class, B.class, A.class, A.class};
    int i = 2;
    Object object = array[i].newInstance();
}

The class must have a default constructor (one with no arguments) in order for newInstance() to work.
