Memory 内存类，包含以下属性 type :类型，例如”ddr”\”ddr2”\”ddr4”等 speed:速度，例如1333\1600等 voltage:电压，例如”高电压”\”低电压” spec:规格,每条的容量，例如4\8\16 Cpu 处理器类，包含以下属性 cores：核心数，如1\2\4等 speed：速度，如2.5\3.5\4.0等 socket：插槽类型，例如”am3”\”fm1”\”lga1155”等 Mainboard主板类，包含以下属性 socketType：cpu插槽类型，例如”am3”\”fm1”\”lga1155”等 memoryType :内存类型，例如”ddr”\”ddr2”\”ddr4”等 memoryCount：最大支持内存条数，如2,4,8等 memoryCapacity：最大支持内存容量，如2,4,8,32等 Computer电脑类，包含以下属性： 一块主板 Mainboard mainboard。 一组内存:Memory [] memories 一个处理器:Cpu cpu; Factory 组装工厂类，包含一个方法 public static Computer makeComputer(Mainboard mainboard,Memory [] memories,Cpu cpu){} 这个方法返回一个Computer实例，组成computer的配件都在圆括号中。 注意：Cpu插槽和主板插槽类型不匹配返回null 内存type和主板内存类型不匹配返回null 单条内存容量大于主板单条内存最大容量返回null(主板单条内存最大容量=最大支持内存容量/最大支持内存条数) 若给定内存条数量大于主板支持内存条数，则以主板支持为准。 public static String showDetail(Computer computer){} 这个方法返回该电脑的配置单，需要显示cpu的全部属性，内存总量，内存条数量，内存类型，内存类型，格式可以自定义 。这道题该怎么写
