JSTL c:remove tag

Example of <c:remove> Tag :

In the example given below we will describe you how to use the <c:remove> tag in jsp. In the example I have first set the value of a variables using <c:set> tag and then removed the one value using <c:remove> tag of JSTL core tag library. So as an output you will see the values that I set to variables 'var1' & 'var2' but in the further step you will see there is only value and the other value is removed. This is because I removed the value of the variable 'var1' using <c:remove> var="var2" />
