  - ## Context
  
  Exploring the limitations of traditional MVC architecture and the potential benefits of adopting an Elm-like architecture for state management in Java.
- ## MVC Code Example in Java

- ```java
	  // Model
	  public class CounterModel {
	    private int count;
	  
	    public int getCount() {
	        return count;
	    }
	  
	    public void increment() {
	        this.count++;
	    }
	  
	    public void decrement() {
	        this.count--;
	    }
	  }
	  
	  // View
	  public class CounterView {
	    public void printCounterDetails(int count) {
	        System.out.println("Counter: " + count);
	    }
	  }
	  
	  // Controller
	  public class CounterController {
	    private CounterModel model;
	    private CounterView view;
	  
	    public CounterController(CounterModel model, CounterView view) {
	        this.model = model;
	        this.view = view;
	    }
	  
	    public void userIncrement() {
	        model.increment();
	        view.printCounterDetails(model.getCount());
	    }
	  
	    public void userDecrement() {
	        model.decrement();
	        view.printCounterDetails(model.getCount());
	    }
	  }
	  
	  // Main Application
	  public class Main {
	    public static void main(String[] args) {
	        CounterModel model = new CounterModel();
	        CounterView view = new CounterView();
	        CounterController controller = new CounterController(model, view);
	  
	        controller.userIncrement();  // Output: Counter: 1
	        controller.userDecrement();  // Output: Counter: 0
	    }
	  }

- ## Elm-like Architecture Code Example in Java
  collapsed:: true
- ```java
	  // Model
	  public class ElmModel {
	      private int count;
	  
	      public ElmModel(int initialCount) {
	          this.count = initialCount;
	      }
	  
	      public int getCount() {
	          return count;
	      }
	  
	      public ElmModel update(String action) {
	          if ("INCREMENT".equals(action)) {
	              return new ElmModel(this.count + 1);
	          } else if ("DECREMENT".equals(action)) {
	              return new ElmModel(this.count - 1);
	          }
	          return this;
	      }
	  }
	  
	  // View (Same as MVC, typically you'd re-render here based on new model)
	  public class ElmView {
	      public void printCounterDetails(int count) {
	          System.out.println("Counter: " + count);
	      }
	  }
	  
	  // Main Application
	  public class ElmMain {
	      public static void main(String[] args) {
	          ElmModel model = new ElmModel(0);
	          ElmView view = new ElmView();
	  
	          // Initial Render
	          view.printCounterDetails(model.getCount());
	  
	          // Update and Re-render
	          model = model.update("INCREMENT");
	          view.printCounterDetails(model.getCount());
	  
	          model = model.update("DECREMENT");
	          view.printCounterDetails(model.getCount());
	      }
	  }

- ## Discussion Points
  collapsed:: true
- ### Memory Concerns with Immutability
  - Traditional Java developers might express concerns over the memory inefficiency of creating new model objects for every state change.
  - Modern JVMs are optimized for short-lived objects.
  - Persistent data structures can be used to mitigate memory concerns.
  - ### The Missing Controller
  - The Elm architecture disperses the responsibilities of what traditionally would be in the controller.
  - The `update` function is focused only on state management, resulting in a more modular and testable architecture.
  - ### Re-rendering in Java
  - In a front-end setting, re-rendering is natural. In Java, this could be conceptualized as triggering subsequent processes dependent on the state.
  - ## High-Stakes Communication Strategy
		  
		   Acknowledge potential concerns such as memory inefficiency and missing controllers upfront.
		   Dive deep into how modern programming paradigms offer solutions, including persistent data structures and decentralized responsibilities.
