JSTL forEach List Iteration

JSTL forEach List Iteration Example explains about How to Iterating a List using JSTL Taglib

List is an ordered pair of objects, It may contains duplicates, but it keeps correct the insertion order

Consider a JSP page, which contains a ArrayList with lot of items inside it and we need to iterate and display the items inside that particular ArrayList

You can access an element from this collection using ${item} using a variable var="item"
