Answer 2

Answer:

Conditional statements are an important part of any programming language. These statements allow you to selectively execute parts of the program based on certain conditions. JSTL provides several tags that allow this sort of conditional execution.

Explanation:

Using the <c:if> Tag

Nearly every programming language contains an if statement, and JSTL is no exception. The JSTL if statement is implemented using the <c:if> tag. There are two forms of the JSTL if statement:

<!-- Syntax 1: Without body content -->

<c:if test="testCondition"

var="varName" [scope="{page|request|session|application}"]/>

<!-- Syntax 2: With body content -->

<c:if test="testCondition"

[var="varName"] [scope="{page|request|session|application}"]>

body content

</c:if>
