Need to run something after declaring an object

Processing Coding Questions

I’m currently writing a bit of code I want to reuse in other projects. It’s a GUI framework. The problem is that I don’t want to constantly keep typing in a specific line of code every single time I start using whatever feature I need from each function. The solution was simple enough, I created an update function(stub), but now I need to run a function to add the new object to the code automatically upon the creation of the object. How would I achieve this? I want to do this in JuiceUI, and not JuiceUI_Example The code is below, albeit quite poorly made.

JuiceUI_Example(main file)

JuiceUI example = new JuiceUI();
JuiceUI.button ButtonA = example.new button();

void setup() {
 size(640,480);
 surface.setTitle("JuiceUI Testing Program!");
 surface.setResizable(true);
 surface.setLocation(100, 100);
 frameRate(60);
 //Button A setup
 
}

void draw() {
  ButtonA.disable = false;
  if (frameCount%30==0) {
  example.update(); 
  print("ButtonA", ButtonA.disable, "\n");
  }
}

JuiceUI(the framework I’m writing)

public class JuiceUI {
  void update() {
  print("Update has been called at frame", frameCount, "\n");
  }

//Button manipulation
  public class button {
  public float posx = 0;
  public float posy = 0;
  int sizex = 100;
  int sizey = 50;
  String text;

  boolean disable = false;
  byte status = -127;
  void autorun() {
    
  }
  }
}

I can answer this one myself. This one was ridiculously easy, and a clear example of why you should do research before going from imperative to object orientated. It’s called a constructor, and looks a bit like this.

//Button manipulation
  public class button {
. . .
  button() {
    print("New button created.");
  }
