JSTL forEach Map Iteration

JSTL forEach Map Iteration Example explains how to iterating a map using JSTL Taglib

Map is an object that stores key / value pairs. You can find its value from a particular key. Keys must be unique, but values may be duplicated 

Consider a JSP page, which contains a HashMap with lot of key value pairs inside it and we need to iterate and display the values inside that particular HashMap

You can access ${entry.key} and ${entry.value} from a Map using a variable var="entry"

This JSTL 'c:forEach is available for all the List / Collection implementations in java

Following example shows How to iterate a JSTL HashMap using JSTL c:forEach
