这篇博客展示了如何使用Java实现工厂模式，创建CPU和RAM的接口及其实现类，包括PCCPU、MacCPU、PCRAM和MacRAM。通过HardWareFactory接口和PCFactory、MacFactory类，实现了根据不同平台生产不同硬件的逻辑。

类图

java代码示例

1.CPU接口

package fire;

public interface CPU {

public void run();
}

2.PCCPU类

package fire;

public class PCCPU implements CPU{

   @Override
   public void run() {
       System.out.println("PC CPU正在运行");
   }

}

3.MacCPU类

package fire;

public class MacCPU implements CPU{

   @Override
   public void run() {
       System.out.println("Mac CPU正在运行");
   }

}

4. RAM接口

package fire;

public interface RAM {
public void run();
}

5.PCRAM类

package fire;

public class PCRAM implements RAM{

   @Override
   public void run() {
       // TODO Auto-generated method stub
       System.out.println("PC ARM正在运行");
   }

}

6.MacRAM类

package fire;

public class MacRAM implements RAM{

   @Override
   public void run() {
       // TODO Auto-generated method stub
       System.out.println("Mac ARM正在运行");
   }

}

7.HardWareFactory接口

package fire;

public interface HardWareFactory {
public CPU produceCPU();
public RAM produceRAM();
}

8.PCFactory类

package fire;

public class PCFactory implements HardWareFactory{

   @Override
   public CPU produceCPU() {
       // TODO Auto-generated method stub
       return new PCCPU();
   }

   @Override
   public RAM produceRAM() {
       // TODO Auto-generated method stub
       return new PCRAM();
   }

}

9. MacFactory类

package fire;

public class MacFactory implements HardWareFactory{

   @Override
   public CPU produceCPU() {
       // TODO Auto-generated method stub
       return new MacCPU();
   }

   @Override
   public RAM produceRAM() {
       // TODO Auto-generated method stub
       return new MacRAM();
   }

}
