本篇文章主要介绍了"php工厂模式 工厂模式学习记录"，主要涉及到php工厂模式方面的内容，对于软件工程感兴趣的同学可以参考一下：
工厂模式（Factory Pattern） 1，Shape接口的定义package factory;publicinterface Shape {void...
工厂模式（Factory Pattern）
1，Shape接口的定义
package factory;
publicinterface Shape {
void draw();
} 2，Circle实现Shape接口
package factory;
publicclass Circle implements Shape {
@Override
publicvoid draw() {
System.out.println("draw a Circle");
}
} 3，Rectangle实现Shape接口
package factory;
publicclass Rectangle implements Shape {
@Override
publicvoid draw() {
System.out.println("draw a rectangle");
}
} 4，Square实现Shape接口
package factory;
publicclass Square implements Shape {
@Override
publicvoid draw() {
System.out.println("draw a Square");
}
} 5，工厂方法类ShapeFactory
package factory;
publicclass ShapeFactory {
staticfinal String CIRCLE="circle";
staticfinal String SQUARE="square";
staticfinal String RECTANGLE="rectangle";
public Shape getShape(String type){
if(type.equals(CIRCLE)){
returnnew Circle();
}elseif(type.equals(RECTANGLE)){
returnnew Rectangle();
}elseif(type.equals(SQUARE)){
returnnew Square();
}else{
returnnull;
}
}
} 6，工厂的使用Demo
package factory;
publicclass FactoryDemo {
publicstaticvoid main(String[] args) {
ShapeFactory factory= new ShapeFactory();
Shape shape=factory.getShape(ShapeFactory.CIRCLE);
shape.draw();
}
}
以上就介绍了php工厂模式 工厂模式学习记录，包括了php工厂模式方面的内容，希望对软件工程有兴趣的朋友有所帮助。
