Using Reflection to get superclass constructor

[cursive flame]

It's my lovable dumb self again.

So, I got an abstract parent class that has two protected constructors:

• one that takes a DataInputStream and a boolean
• one that takes a String

and a bunch of implementing child classes that extend this abstract class.

Each child class uses the constructor that takes a String, like so:

public ImplChildClass(String one, String two) {
  super(one);
  this.two = two;
}

All super standard. Now, I want to be able to construct an implementing class using the abstract classes constructor that takes the DataInputStream and boolean arguments. Google tells me I should be able to do

Constructor<? extends AbstractParentClass> constructor = ImplChildClass.getClass().getDeclaredConstructor(DataInputStream.class, boolean.class);
constructor.setAccessible(true);
constructor.newInstance(dataInputStream, true);

but I'm getting java.lang.NoSuchMethodException when I do that. So, what am I doing wrong?

Still having some issues with this

So no matter what I do, I cannot get the superclass constructor from the implementing class, so I have to be doing something wrong, or it isn't possible

ImplChildClass.class

not ImplChildClass.getClass()

And does the child class have the costructor with DataInputStream and boolean?

because constructors aren't inherited
