Shakl interface
public interface Shape {

void draw();

}

Tortburchak classi
public class Rectangle implements Shape {
@Override

public void draw() {

System.out.println("Shape klasi interfece bup olindi va draw metodidan foydalaniladi Shapeni");

}

}


Kvadrat classi

public class Square implements Shape {
@Override

public void draw() {

System.out.println("Inside Circle::draw() method.");

}

}

Aylana classi

public class Circle implements Shape {
@Override

public void draw() {

System.out.println("Inside Circle::draw() method.");

}

}

Shape factory classini yaratib olamiz. va qatsi shakl ekanligini aniqlimiz
public class ShapeFactory {



// turi shaklidagi ob'ektni olish uchun getShape usulidan foydalaning
public Shape getShape(String shapeType){

if(shapeType == null){

return null;

}

if(shapeType.equalsIgnoreCase("CIRCLE")){

return new Circle();



} else if(shapeType.equalsIgnoreCase("RECTANGLE")){

return new Rectangle();



} else if(shapeType.equalsIgnoreCase("SQUARE")){

return new Square();

}



return null;

}

}

Natija
Inside Circle::draw() method.

Inside Rectangle::draw() method.

Inside Square::draw() method.

MainClassida chaqirib shapni tekshirib kuramiz

public class FactoryPatternDemo {
public static void main(String[] args) {

ShapeFactory shapeFactory = new ShapeFactory();
// Circle ob'ektini oling va uni chizish usulini chaqiring

.

Shape shape1 = shapeFactory.getShape("CIRCLE");
// Circle chizish usulini chaqiring
shape1.draw();
//obyektni boshqattan caqirib rectanglega ulash

Shape shape2 = shapeFactory.getShape("RECTANGLE");
//rectangle metodini chaqirish

shape2.draw();
//turtburchak metodini olib caqirish

Shape shape3 = shapeFactory.getShape("SQUARE");

//turtburchak metodini chaqirish

shape3.draw();

}

}
