Why does .getConstructor fail with a NoSuchMethodException despite zero-arg constructors existing for the class?

java.lang.NoSuchMethodException from a Class.forName instantiation

The 3 classes (Dumb, Dumber, Dummy) in my example are both non-static & non-public. So it’s very possible to find such classes as my example already demonstrates. I’ve split up getDumb() into 2 functions in a separate tab: getSketchInnerClassConstructor() → returns a Class’ Constructor. instantiateSketchInnerClass() → returns an instance from a Constructor. Also made 2 functions to find nested classes: findAllSketchInnerClasses() → returns an array of all inner classes. findSketchNested…

[SOLVED] Instantiating a particular class constructor using reflection

Hello again, oh great Java gurus! I find myself having to instantiate a class from a string using one of its particular constructors. The api for getDeclaredConstructors() indicates this is possible, but the examples I’ve found online of its implementation aren’t clicking for me. Here’s a stripped-down example of what I’m hoping to achieve. import java.lang.reflect.*; // This PApplet processing session // final String THISPROC = this.getClass().getCanonicalName(); final PApplet…
