JSP methods

In this example we are going to show you how we can declare a method and how we can used it. In this example we are making a method named as addNum(int i, int b) which will take two numbers as its parameters and return integer value. We have declared this method inside a declaration directive i.e. <%! -----------%> this is a declaration tag. This tag is used mainly for declaration the variables and methods. In the method we are adding to numbers. To print the content of the method we are using scriptlet tag inside which we are going to use the out implicit object .<% ------- %> This tag is known as Scriptlets . The main purpose of using this tag is to embed a java code in the jsp page.

The code of the program is given below:

<HTML>
  <HEAD>
    <TITLE>Creating a Method</TITLE>
  </HEAD>

  <BODY>
    <font  size="6" color ="#330099"> Method in Jsp </font><br>
    <%!
    int addNum(int n, int m)
    {
      return n + m;
    }
    %>

    <%
    out.println("6 + 2 = " + addNum(6, 2));
    %>
  </BODY>
</HTML>

Output of the program is given below:
