Description
构造计算机类，其中包含其配置信息：处理器、主板、内存、显示器、硬盘等设备，各个设备均有型号（字符串），特别的，处理器有主频（小数）和内核数（整数）、显示器有尺寸（整型）、内存和硬盘有容量数据（GB为单位）。请你尝试构造合适的类和类的关系来表示计算机，并为该计算机类添加计算价格（各设备价格之和）、打印配置信息等方法。重写相关类的equals方法，使得两个配置完全相同的计算机为相同的计算机。重写相关类的toString函数，打印计算机的配置信息。 在main函数中
Input
两个计算机对象，包含 CPU：型号、主频、内核 主板：型号 内存：容量 显示器：尺寸 硬盘：容量
Output
两个对象是否相等 两个对象的配置信息
Sample Input
Corei7 2.8 4 GIGABYTE-B250M-D3H xiede-DDR3 8 SamsungC27F39 27 SEAGATE-ST1000DM010 2048 Corei7 2.8 4 GIGABYTE-B250M-D3H xiede-DDR3 8 SamsungC27F39 27 SEAGATE-ST1000DM010 2048
Sample Output
true Computer1: CPU: Model: Corei7 Frequency: 2.8 Number of Cores: 4 Mainboard: Model: GIGABYTE-B250M-D3H Memory: Model: xiede-DDR3 Size: 8 Screen: Model: SamsungC27F39 Size: 27 Harddisk: Model: SEAGATE-ST1000DM010 Size: 2048 Computer2: CPU: Model: Corei7 Frequency: 2.8 Number of Cores: 4 Mainboard: Model: GIGABYTE-B250M-D3H Memory: Model: xiede-DDR3 Size: 8 Screen: Model: SamsungC27F39 Size: 27 Harddisk: Model: SEAGATE-ST1000DM010 Size: 2048
HINT
为计算机类和各个组成配件都构造类，分别重写toString和equals方法
在计算机类中调用各个配件的equals和toString方法
回车用\n
小数用String.format("%.1f",1.234)
