Question

package company;

public abstract class A {
    public A(int i) {}
    public abstract void func();

}

public class B extends A {
   public B(int i) { super(i); }
   public void func() {}
}


public class C extends A {
   public C(int i) { super(i); }
   public void func() {}
}

How do I dynamically instantiate company.C or company.B by invoking the constructor function (with a certain integer argument) and invoking the func() method? I know we can use the following method and pass an argument, but not sure how to invoke func() method on it.

You can use the Java Reflection .
