### 需求说明 ###

采用面向接口编程思想组装一台计算机

计算机的主要组成部分

CPU

硬盘 Ems

内存 HardDisk

--------------------

Computer.java:

package com.bdqn.demo06;
    
    public class Computer implements Cpu,Ems,HardDisk{
    
        //组装电脑
        public void createNewComputer(Cpu cpu,Ems ems,HardDisk hardDisk){
    
            System.out.println("计算机信息如下:");
            System.out.println("CPU的品牌是:"+cpu.getBrand()+"主频是:"+cpu.getMainFrequency());
            System.out.println("硬盘容量是:"+ems.getEMSCapacity());
            System.out.println("内存容量是:"+hardDisk.getHardDiskCapacity());
        }
    
        @Override
        public String getBrand() {
            return null;
        }
    
        @Override
        public String getMainFrequency() {
            return null;
        }
    
        @Override
        public String getEMSCapacity() {
            return null;
        }
    
        @Override
        public String getHardDiskCapacity() {
            return null;
        }
    }

InterCpu.java:

package com.bdqn.demo06;
    
    public class IntelCpu implements Cpu{
        public String getBrand(){
    
            return "Intel";
        }
    
        @Override
        public String getMainFrequency() {
            return "3.8GHZ";
        }
    }

ComputerEms.java:

package com.bdqn.demo06;
    
    public class ComputerEms implements Ems{
        @Override
        public String getEMSCapacity() {
            return "256G";
        }
    }
    ComputerHardDisk.java:
    package com.bdqn.demo06;
    
    public class ComputerHardDisk implements HardDisk {
        @Override
        public String getHardDiskCapacity() {
            return "16GB";
        }
    }

**Cpu(接口):**

package com.bdqn.demo06;
    
    public interface Cpu {
        //获取品牌
        public abstract String getBrand();
        //获取主频
        public  abstract String getMainFrequency();
    }

**Ems(接口):**

package com.bdqn.demo06;
    
    public interface Ems {
        //获取容量
        public  abstract String getEMSCapacity();
    }

**HardDisk(接口):**

package com.bdqn.demo06;
    
    public interface HardDisk {
        //获取容量
        public abstract String getHardDiskCapacity();
    
    }

**Test.java:**

package com.bdqn.demo06;
    
    public class Test {
        public static void main(String[] args) {
            //创建对象
            Computer computer=new Computer();
            Cpu cpu=new IntelCpu();
            Ems ems=new ComputerEms();
            HardDisk hardDisk=new ComputerHardDisk();
    
            computer.createNewComputer(cpu,ems,hardDisk);
        }
    }

效果实现：
