// Builder Pattern

// 복잡한 단계를 거쳐야 생성되는 객체의 구현을 서브 클래스에게 넘겨주는 패턴

// https://youtu.be/SWbW5ZzeARU

// 일반적인 객체 생성의 경우 구현체가 많아지면 매번 설정해야 하는 단점이 있다.

//Computer computer = new Computer("i7", "16g", "256gb ssd");

//System.out.println(computer.toString());

//=======================================================================

// Example 1

ComputerFactory factory = new ComputerFactory();

// LG - gram builder

factory.setBluePrint(new LgGramBlueprint());

factory.make();

Computer lgComputer = factory.getComputer();

System.out.println(lgComputer.toString());

// Apple - MacBook builder

factory.setBluePrint(new MacBookBlueprint());

factory.make();

Computer appleComputer = factory.getComputer();

System.out.println(appleComputer.toString());

//=======================================================================

//=======================================================================

// Example 2 - 인자가 많을 경우 생성 패턴

Computer computer = ComputerBuilder

.start()

.setCpu("i7")

.setRam("8g")

.build();

System.out.println(computer.toString());

//=======================================================================
