Builder Design Pattern Java Code Example
I’ve received a lot of requests for a how-to on this tumbler so here it is! Factory pattern is used when the factory can easily create the entire object within one method call.The append() method is one step of the process, just like a step in our Starbucks example.
Starbucks solves the problem with the same "pattern" we use in messaging architectures -- they use a Correlation Identifier. Thank you so much!
Does it utilize the Builder pattern?In Java standard library, StringBuilder extends AbstractStringBuilder.package designpatterns.builder;// produce to be builtclass Starbucks {private String size;private String drink;public void setSize(String size) {this.size = size;}public void setDrink(String drink) {this.drink = drink;}}//abstract builderabstract class StarbucksBuilder {protected Starbucks starbucks;public Starbucks getStarbucks() {return starbucks;}public void createStarbucks() {starbucks = new Starbucks();System.out.println("a drink is created");}public abstract void buildSize();public abstract void buildDrink();}// Concrete Builder to build teaclass TeaBuilder extends StarbucksBuilder {public void buildSize() {starbucks.setSize("large");System.out.println("build large size");}public void buildDrink() {starbucks.setDrink("tea");System.out.println("build tea");}}// Concrete builder to build coffeeclass CoffeeBuilder extends StarbucksBuilder {public void buildSize() {starbucks.setSize("medium");System.out.println("build medium size");}public void buildDrink() {starbucks.setDrink("coffee");System.out.println("build coffee");}}//director to encapsulate the builderclass Waiter {private StarbucksBuilder starbucksBuilder;public void setStarbucksBuilder(StarbucksBuilder builder) {starbucksBuilder = builder;}public Starbucks getstarbucksDrink() {return starbucksBuilder.getStarbucks();}public void constructStarbucks() {starbucksBuilder.createStarbucks();starbucksBuilder.buildDrink();starbucksBuilder.buildSize();}}//customerpublic class Customer {public static void main(String[] args) {Waiter waiter = new Waiter();StarbucksBuilder coffeeBuilder = new CoffeeBuilder();//Alternatively you can use tea builder to build a tea//StarbucksBuilder teaBuilder = new TeaBuilder();waiter.setStarbucksBuilder(coffeeBuilder);waiter.constructStarbucks();//get the drink builtStarbucks drink = waiter.getstarbucksDrink();}}Builder pattern is used when there are many steps to create an object.
Said they got the QR from pinterest, but it wasn't working for me, so I remade it. However, there is a common mistake here.

You can compare with the class diagram at the beginning and find out another reason.StringBuilder strBuilder= new StringBuilder();strBuilder.append("one");strBuilder.append("two");strBuilder.append("three");String str= strBuilder.toString();Builder pattern has been used in a lot of libraries.
