Hi
I have a question regarding what is the best way to get information from a vector
(following are the examples: both work fine but which one should be used)
>From my JSP page I call my Java bean which connects to database, get the results and
>returns a vector to JSP. In the JSP page I have two choices I can use ENUMERATION
>and get the information from database Or I can get the size of the vector and use a
>for loop to read the info in the vector. Both of these work fine.
I want to know which is better performance-wise so I should stick to using that one
only.
Any suggestions will be greatly appreciated. If should do be doing some totally new
concept, please let me know.
Thanks
******** Enumeration Example *************************
Vector vrs = new Vector();
vrs = sqlAbcBean.getKeyPersonnel(district);
Enumeration rs = vrs.elements();
while(rs.hasMoreElements()){
a = rs.nextElement().toString();
b = rs.nextElement().toString();
c = rs.nextElement().toString();
d = rs.nextElement().toString();
e = rs.nextElement().toString();
e = rs.nextElement().toString();
}
******** For Loop Example *************************
Vector vrs = new Vector();
vrs = sqlAbcBean.getKeyPersonnel(district);
for(int i = 0; i < vrs.size(); i=i+6)
{
a = vrs.get(i).toString();
b = vrs.get(i+1).toString();
c = vrs.get(i+2).toString();
d = vrs.get(i+3).toString();
e = vrs.get(i+4).toString();
f = vrs.get(i+5).toString();
}
