How to define variable in Velocity

This Example shows you how to define a variable in velocity.

Methods 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 Choudhary"): This is a statement named 'set', generally begins with # character. Here we have assign the list with character $.

$list: This statement is used for display the value of list variable.

SetValue.java:

import java.io.*;



import org.apache.velocity.*;

import org.apache.velocity.app.*;

import org.apache.velocity.tools.generic.RenderTool;



public class SetValue {



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

  Velocity.init();

  Template t = Velocity.getTemplate("./src/SetValue.vm");



  VelocityContext context = new VelocityContext();

  

  Writer writer = new StringWriter();

  t.merge(context, writer);



  System.out.println(writer);

  }

}

SetValue.vm:

#set(
$name = "Komal Choudhary")
