<c:forEach>, <c:forTokens> Tags

These tags encapsulate the for, while, do-while loops in Java.

By comparison, the <c:forEach> tag is more versatile as it iterates over objects in a collection.

The <c:forTokens> tag splits a string into an array using specified delimiters and then iterates over them.

&lt;c:forEach
    items="<object>"
    begin="<int>"
    end="<int>"
    step="<int>"
    var="<string>"
