怎么将list转成数组

如何将list转成数组?
我要访问一个类中的数据:
Java code
package User;import java.util.List;import Community.CommunityEntity;public class TestDemo{    public static void main(String[] args)     {        System.out.println("这是测试CommunityEntity类中的数据:");        DbStore abcd = new DbStore();        List<CommunityEntity> list = abcd.getCommList();        CommunityEntity ce = new CommunityEntity();             String commList[] = list.toArray(new String[]{});                for(int i=0;i<abcd.getCommList().size();i++)        {            System.out.println("小区编号:");            System.out.println("小区名称:");            System.out.println("小区经理:");            System.out.println("区域:");            System.out.println("状态:");            System.out.println("渗透率:");            System.out.println("覆盖用户数:");            System.out.println("\r\n");        }    }}


剩下的代码:
Java code
package User;import java.util.ArrayList;import java.util.List;import Community.CommunityEntity;public class DbStore {    private List<CommunityEntity> commList = new ArrayList<CommunityEntity>();    public DbStore() //初始化用户实体数组    {        CommunityEntity com1 = new CommunityEntity();        com1.setCommId("001");        com1.setCommName("新升新苑");        com1.setCommManager("大漠");        com1.setCommArea("高新区");        com1.setCommStatue("可放装");        com1.setPermeability(61);        com1.setUserCount(221);                CommunityEntity com2 = new CommunityEntity();        com2.setCommId("002");        com2.setCommName("新盛花园");        com2.setCommManager("大漠");        com2.setCommArea("吴中区");        com2.setCommStatue("可放装");        com2.setPermeability(62);        com2.setUserCount(222);                CommunityEntity com3 = new CommunityEntity();        com3.setCommId("003");        com3.setCommName("新唯家园");        com3.setCommManager("大漠");        com3.setCommArea("工业园区");        com3.setCommStatue("可放装");        com3.setPermeability(63);        com3.setUserCount(223);                CommunityEntity com4 = new CommunityEntity();        com4.setCommId("004");        com4.setCommName("蠡东花园");        com4.setCommManager("大漠");        com4.setCommArea("相城区");        com4.setCommStatue("可放装");        com4.setPermeability(64);        com4.setUserCount(224);                CommunityEntity com5 = new CommunityEntity();        com5.setCommId("005");        com5.setCommName("朱家庄新村");        com5.setCommManager("大漠");        com5.setCommArea("金阊区");        com5.setCommStatue("可放装");        com5.setPermeability(65);        com5.setUserCount(225);                commList.add(com1);        commList.add(com2);        commList.add(com3);        commList.add(com4);        commList.add(com5);    }    public void setCommList(List<CommunityEntity> commList)     {        this.commList = commList;    }    public List<CommunityEntity> getCommList()    {        return commList;    }}

Java code
package Community;public class CommunityEntity {    private String commId;    private String commName;    private String commManager;    private String commArea;    private String commStatue;    private double permeability;    private int userCount;    public String getCommId()     {        return commId;    }    public void setCommId(String commId)    {        this.commId = commId;    }    public String getCommName()     {        return commName;    }    public void setCommName(String commName)     {        this.commName = commName;    }    public String getCommManager()     {        return commManager;    }    public void setCommManager(String commManager)    {        this.commManager = commManager;    }    public String getCommArea()    {        return commArea;    }    public void setCommArea(String commArea)    {        this.commArea = commArea;    }    public String getCommStatue()     {        return commStatue;    }    public void setCommStatue(String commStatue)     {        this.commStatue = commStatue;    }    public double getPermeability()     {        return permeability;    }    public void setPermeability(double permeability)    {        this.permeability = permeability;    }    public int getUserCount()     {        return userCount;    }    public void setUserCount(int userCount)     {        this.userCount = userCount;    }}
