JSTL Core <c:choose>, <c:when>, <c:otherwise> Tag

The < c:choose > tag is a conditional tag that establish a context for mutually exclusive conditional operations. It works like a Java switch statement in which we choose between a numbers of alternatives.

The <c:when > is subtag of <choose > that will include its body if the condition evaluated be ‘true’.

The < c:otherwise > is also subtag of < choose > it follows &ltwhen > tags and runs only if all the prior condition evaluated is ‘false’.

The c:when and c:otherwise works like if-else statement. But it must be placed inside c:choose tag.
