模板方法设计模式

 

package com.jmj.pattern.template;

public abstract class AbstractClass {

    //模板方法定义
    public final void cookProcess(){
        pourOil();
        heatoil();
        pourVegetable();
        pourSauce();
        fry();
    }


    public void pourOil(){
        System.out.println("倒油");
    }
    public void heatoil(){
        System.out.println("热油");
    }
    public void fry(){
        System.out.println("炒炒到熟啊");
    }
    public abstract void pourVegetable();

    public abstract void pourSauce();


}

package com.jmj.pattern.template;

public class ConcreteClass_BaoCai extends AbstractClass {

    @Override
    public void pourVegetable() {
        System.out.println("下锅的蔬菜是包菜");
    }

    @Override
    public void pourSauce() {
        System.out.println("下锅的酱料是辣椒");
    }
}

package com.jmj.pattern.template;

public class ConcreteClass_Caixin extends AbstractClass {

    @Override
    public void pourVegetable() {
        System.out.println("下锅的蔬菜是菜心");
    }

    @Override
    public void pourSauce() {
        System.out.println("下锅的酱料是蒜蓉");
    }
}

package com.jmj.pattern.template;

public class Client {
    public static void main(String[] args) {
        ConcreteClass_BaoCai concreteClass_baoCai = new ConcreteClass_BaoCai();
        concreteClass_baoCai.cookProcess();

        ConcreteClass_Caixin concreteClass_caixin = new ConcreteClass_Caixin();
