The if...else block starts out as an ordinary Scriptlet, but the Scriptlet is closed at each line with HTML text included between the Scriptlet tags.
Example
<%! int day = 3; %> <html> <head> <title>IF...ELSE Example</title> </head> <body> <% if (day == 1 || day == 7) { %> <p> Today is weekend</p> <% } else { %> <p> Today is not weekend</p> <% } %> </body> </html>
The above code will generate the following result −
Today is not weekend
