There are many operators in JSP that are used in EL like arithmetic and logical operators to perform an expression. In JSP, whatever present in the braces gets evaluated at runtime sent to the output stream.The expression is a valid EL expression and it can be mixed with a static text and can be combined with other expression to form larger expression.To get a better idea, on how expression works in JSP, we will see below example. In this example, we will see how EL is used as an operator to add two numbers (1+2) and get the output respectively.

Code Line 11: Expression Language (EL) is set where we are adding two numbers 1+2, hence it will give output as 3.When you execute the above code, you will have the following Output. Expression is: 3 (As numbers 1+2 will be added and serve as an output).JSP provides the power of Java to be embedded in the application. We can use all the APIs and building blocks of Java in JSP programming including control flow statements which include decision making and the loop statements. There are two types of flow control statements described below ĭecision-making statement in JSP is based on whether the condition set is true or false.
There are two types of decision-making statements described below:
“If else” statement is basic of all control flow statements, and it tells the program to execute the certain section of code only if the particular test evaluates to true. This condition is used to test for more than one condition whether they are true or false.
