用java读取excle文件用list,map接收，list实现了，map怎么也不行,急死了。

public static void main(String[] args) throws Exception {
Workbook workbook=null;
Sheet sheet=null;
List list =new ArrayList();
InputStream input=new FileInputStream("E://tt.xls");
workbook =Workbook.getWorkbook(input);
sheet=workbook.getSheet(0);
for (int i = 0; i <sheet.getRows(); i++) {
String []str=new String[sheet.getColumns()];
for (int j = 0; j <sheet.getColumns(); j++) {
Cell cell=sheet.getCell(j,i);
str[j]=cell.getContents();
}
list.add(str);
}
for (int i = 0; i < list.size(); i++) {
String[]str=(String[]) list.get(i);
for (int j = 0; j < str.length; j++) {
System.out.println(str[j]);
}
}
}
这是list的方法，求一个map的跟遍历输出谢谢。
首先感谢，劳驾你再帮帮忙，map中key的值是标题，比如标题是姓名，年龄，住址。数据是张三，12，海南。

import java.io.FileInputStream;
import java.io.InputStream;
import java.util.*;
import jxl.*;
public class Test3{
public static void main(String[] args) throws Exception {
Workbook workbook=null;
Sheet sheet=null;
TreeMap<Integer,String[]> map = new TreeMap<Integer,String[]>();
InputStream input=new FileInputStream("D://tt.xls");
workbook =Workbook.getWorkbook(input);
sheet=workbook.getSheet(0);

for (int i = 0; i <sheet.getRows(); i++) {
String []str=new String[sheet.getColumns()];

for (int j = 0; j <sheet.getColumns(); j++) {
Cell cell=sheet.getCell(j,i);
str[j]=cell.getContents();
}
map.put(i+1, str);
}
for (int i = 0; i < map.size(); i++) {

for (int j = 0; j < map.get(i+1).length; j++) {
System.out.print(map.get(i+1)[j]+" ");
}
System.out.println();
}
}
}
你是想要这种效果吗？
