1、1、List相关操作/***创建一个Computer类**@authorJohn**/publicclassComputer{intid;StringmotherBoardType;StringcpuType;inthardDiskSize;intmemerySize;StringgraphicsCardType;intcomputerPirce;//Computer构造方法publicComputer(intid,StringmotherBoardType,StringcpuType,inthardDiskSize,intmemerySize,String

2、graphicsCardType,intcomputerPirce){super();this.id=id;this.motherBoardType=motherBoardType;this.cpuType=cpuType;this.hardDiskSize=hardDiskSize;this.memerySize=memerySize;this.graphicsCardType=graphicsCardType;this.computerPirce=computerPirce;}//重写父类toString方法publicStringtoString(){

3、return"编号："+id+",主板型号："+motherBoardType+",cpu型号："+cpuType+",硬盘容量："+hardDiskSize+",内存容量："+memerySize+",显卡型号："+graphicsCardType+",价格："+computerPirce;}//为计算机添加CPU型号publicvoidaddCpuType(StringcpuType){this.cpuType=cpuType;}//为计算机添加主板型号publicvoidaddMotherBoardType(StringmotherBoardType)

4、{this.motherBoardType=motherBoardType;}//为计算机添加硬盘大小publicvoidaddhardDiskSize(inthardDiskSize){this.hardDiskSize=hardDiskSize;}//为计算机添加内存大小publicvoidaddMemerySize(intmemerySize){this.memerySize=memerySize;}//为计算机添加显卡型号publicvoidaddgraphicsCardType(StringgraphicsCardType){this.graphi

5、csCardType=graphicsCardType;}//设置计算机价格publicvoidsetComputerPrice(intcomputerPirce){this.computerPirce=computerPirce;}//获取计算机价格publicintgetComputerPirce(){returncomputerPirce;}}importjava.util.ArrayList;importjava.util.List;importjava.util.Scanner;importcom.John.tools.Computer;/***题

6、目：（1）要求使用ArrayList存储计算机对象，形如：ArrayListcList=new*ArrayList();**（2）为ArrayList对象（例如：上面的cList）添加3个元素。**（3）模拟用户输入（Scanner对象）获取对应的Computer信息，并且输出具体的参数。**（4）遍历输出ArrayList中的Computer，同时输出Computer的详细信息。**@authorJohn**/publicclassDemo061_1{publicstaticvoidmain(String[]args

7、){ListcList=newArrayList();Computerc1=newComputer(0,"华硕","intel",500,4,"nvidia",4000);Computerc2=newComputer(1,"联想","amd",500,2,"amd",3000);Computerc3=newComputer(2,"三星","intel",500,4,"amd",3500);cList.add(c1);cList.add(c2);cList.add(c3);Scannersc=newScanner(Sys
