隐藏复杂过程

仅仅关心输入与结果

 

普通简单工厂

多方法简单工厂

工厂方法模式

 

 

package com.songlk.factory;

public interface IMouse {
      String  getMouceInfo();
}

package com.songlk.factory;

public class HPMouse implements IMouse {
    @Override
    public String getMouceInfo() {
        System.out.println("-----hp mouse");
        return "hp mouse";
    }
}

//-----------------------普通简单工厂模式
