Question

wend Problem 2 (25 points) Henry Ford, the brilliant inventor and industrialist, has hired You to design the assembly lne for his new car, the model-ul. The model-U has four assembles: the engine, the steering mechanism, the electrical system and the chassis. Each assembly consists of two Each part has a name and the state of being parts. assembled (true) or disassembled (falsel The parts of each assembly are as folows: values li Part spark li Part) Plugs SteeringMechanismc wheels Part ade 1 Part) The assembly ine works as folows: Eath asseml is assembled by changing the state ofeach of bly Perts to true priming message includna the part name and "s assembled.

Explanation / Answer

//Assembly.java

public interface Assembly {
   public void assemble();
   public boolean qualityControl();
}

//Part.java

public class Part {

   String name;
   boolean state;
  
  
   public Part(String s){ // Getting Part name
       this.name=s;
   }

// Getting state of part
   public boolean getState() {
       return state;
   }

   public void setState(boolean state) {
       this.state = state;
   }
  
  
}

//ElectricalAssembly.java

public class ElectricalAssembly implements Assembly{

   Part starter,distributer;
  
   public ElectricalAssembly(){
       System.out.println("Electrical Assembly Line");
   }
  

// Overriding the methods of Interface Assembly
   @Override
   public void assemble() {
       starter = new Part("Audio Device");
       System.out.println("The Starter is:"+starter.name);
       starter.setState(true); // Setting the state of quality
   }

   @Override
   public boolean qualityControl() {
       boolean b = starter.getState(); // Getting the state of quality
       return b;
   }
  

}

//EngineAssembly.java

public class EngineAssembly implements Assembly{

   Part valves,sparkPlugs;
  
   public EngineAssembly(){
       System.out.println("Engine Assembly Line");
   }
  
   @Override
   public void assemble() {
       valves = new Part("Globe Valve");
       System.out.println("The valve is:"+valves.name);
       valves.setState(false);
   }

   @Override
   public boolean qualityControl() {
       boolean b = valves.getState();
       return b;
   }
  
  
}

//SteeringAssembly.java

public class SteeringAssembly implements Assembly{

   Part wheel,axle;
  
   public SteeringAssembly(){
       System.out.println("Steering Assembly Line");
   }
  
   @Override
   public void assemble() {
       wheel = new Part(" Closed End Axle Nut");
       System.out.println("The Wheel is:"+wheel.name);
       wheel.setState(false);
   }

   @Override
   public boolean qualityControl() {
       boolean b = wheel.getState();
       return b;
   }
  
  
}

//ChasisAssembly.java

public class ChasisAssembly implements Assembly{

   Part frame,cab;
  
   public ChasisAssembly(){
       System.out.println("Chasis Assembly Line");
   }
  
   @Override
   public void assemble() {
       frame = new Part("Monocoque Chassis");
       System.out.println("The Chasis Frame is:"+frame.name);
       frame.setState(true);
      
   }

   @Override
   public boolean qualityControl() {
       boolean b = frame.getState();
       return b;
   }

}

//ModelUI.java

public class ModelUI{

   public static void main(String[] args) {
//Creating Electrical assembly of type Assembly
       Assembly electAssembly = new ElectricalAssembly();

       electAssembly.assemble();
       if(electAssembly.qualityControl()){ // Checking the quality whether it returns true or false
      
       }else{
           System.err.println("Electrical Assembler has no quality...");
       }
      
       System.out.println("************************************ ");
       //Creating Steering assembly of type Assembly
       Assembly steerAssembly = new SteeringAssembly();
       steerAssembly.assemble();
       if(steerAssembly.qualityControl()){
          
       }else{
           System.err.println("Steering Assembler has no quality..");
       }
      
      
       System.out.println("************************************ ");

//Creating Engine assembly of type Assembly

       Assembly engineAssembly = new EngineAssembly();
       engineAssembly.assemble();
       if(engineAssembly.qualityControl()){
          
       }else{
           System.err.println("Engine Assembler has no Quality..");
       }
      
       System.out.println("************************************ ");

//Creating Chasis assembly of type Assembly

       Assembly chasisAssembly = new ChasisAssembly();
       chasisAssembly.assemble();
       if(chasisAssembly.qualityControl()){
          
       }else{
           System.err.println("Chasis Assembly has no Quality..");
       }

   }

}

Output:

Electrical Assembly Line
The Starter is:Audio Device
************************************

Steering Assembly Line
The Wheel is: Closed End Axle Nut
************************************

Steering Assembler has no quality..
Engine Assembly Line
The valve is:Globe Valve
Engine Assembler has no Quality..
************************************

Chasis Assembly Line
The Chasis Frame is:Monocoque Chassis
