JSP: Create Dynamic 2 Column Table looping through iter.hasNext()

Question

Hi,
I have created an ArrayList which I populate with 2 strings per element - if such a thing exists. for example my array would have
{ccc, email}
{bbb,ip}
{aaa,dsl}
{ddd,tv}
I then sort this list using Collections.sort in which case I end up with the following:
aaa, dsl
bbb, ip
ccc, email
ddd, tv
However, I want display the contents in 1 table with 2 columns with a check box in front of each
i.e.
checkbox - aaa, dsl checkbox ccc, email
checkbox- bbb, ip checkbox ddd, tv
I would be happy if the table was like the above, however, even if if bbb,ip printed in the right column I would be ok.
This list example only contains 4 rows now but it could be 5 rows, 6 rows, 7 etc. It can grow/strink so that would be dynamic as well.
I think I need to build a for loop or while loop and to somehow spit out the contents of the first element then increment and check against total lsit and do the second td statement etc. But I am not totally sure. Anyhow, I hope I haven't confused anyone who reads this. Appreciate any help or direction. Thanks

Answer 1

the reason each list element contains 2 pieces of data is so that I can keep the login and type together for sorting purposes and can probably display the login -aaa along with the correct type Email etc.
here is a snip of the code if it will help.
List listTmp = new ArrayList();
ArrayList allLogins = new ArrayList();
for(int i=0;i<service_output.length;i++)
String[] tmpStr = new String[2];
n = service_output.indexOf('(');
if (n > 0)
serviceType = service_output[i].substring(0, n);
restOfString = service_output[i].substring(n+1);
int atsign_index = 0;
atsign_index = restOfString.indexOf('@');
if ((atsign_index) > 0)
loginPrefix = restOfString.substring(0, atsign_index);
tmpStr[0] = loginPrefix;
tmpStr[1] = serviceType;
LoginServType login1 = new LoginServType (tmpStr[0], tmpStr[1]);
allLogins.add(login1);
serviceCount++;
else
continue;
else
continue;
roundServices= new BigDecimal(serviceCount/maxcols).setScale(2, BigDecimal.ROUND_UP);
Collections.sort(allLogins);
//Iterator iter = allLogins.iterator();
for (Iterator iter = allLogins.iterator(); iter.hasNext();)
LoginServType loginiter = (LoginServType)iter.next();
String tempService = myformat.translateService(loginiter.getServType());
