String Operators

EcmaScript has several operators that produce special effects when used with Strings. For instance, the + operator concatenates strings. The comparison operators compare two strings using alphabetical order. Note that all capitol letters come before all lowercase letters.

Here are some examples:

<% request.setAttribute("strArray", new String[] {"Harrison", "Ford", "abc", "ABC", "1", "2"}); %> <%--
Name Value
strArray[]
--%>
