vector pagination

[michael yue]

I want to do pagination for jsp and planning to use vector for it. After I put all the data into the vactor, I not sure how to proceed. Should I use IndexOf method for vector? For example I want 20 records in a page so i should do something like below.
for(x=0, x<=myvector.lastIndexOf(), x=x+20){
(for i=0, i<=x, i++){
myvector.indexOf(i);
}
}
Is it correct? Or maybe someone have a better idea.

Rollin,
Im not sure If there is any method called indexOf(int);which accepts int argument.
And I guess for your requirement you can use elementAt(int index);which will return you java.lang.Object. So you need to cast it to appropriate Class.
Hope this Helps

Rollin,
Also, you only need one loop. Since you are only displaying one page at a time, you can loop through just the correct 20 elements.

Will using third party components such as those in jsptags.com increase the performance such as becoming faster compared to vectors?

I guarantee you that the operation of Vector will never be significant in the speed of any servlet. Look at the source code for java.util.Vector - it is a really simple class.
