Use if and elseif statements in velocity

This Example shows you how to use If and elseif in velocity. The method used in this example are described below:-

1:- Initialize velocity run time engine through method init().
2:- Create object of VelocityContext Class.
3:- Create Template class object, Template class object is used for controlling template methods and properties.

template.merge(context, writer): Merge method of the Template class is used here for merging the VelocityContext class object to produce the output.Template class object is used for controlling template methods and properties.

#set($name = "komal"): This is a statement named 'set', it generally begins with # character. Here we have assign the name 'komal' with character $ .

#if($name =="komal"): This is a statement for checking the variable name with String 'komal'. if condition is true it will print message "Hi komal....." if condition is false then it will check the value of name with "ajay" if condition is true it will print message "Hi ajay ....." if both condition false it will print message "Hi.......".

Condition.java

package velocity.conditionals;



import java.io.*;

import java.util.*;

import org.apache.velocity.*;

import org.apache.velocity.app.*;



public class Condition {

  public static void main(String[] args) throws Exception {

  Velocity.init();



  Template template = 

Velocity.getTemplate("./src/velocity/conditionals/ifelseif.vm");



  VelocityContext context = new VelocityContext();

  

 

  Writer writer = new StringWriter();

  template.merge(context, writer);



  System.out.println(writer);

  }

}

ifelseif.vm

#set($name ="komal")



#if($name=="komal")

Hi Komal ...
