How to set a variable value using velocity

     

This Example shows you how to set variable value using 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($list[Ajay, Bhanu, Komal, Shuki, Rakesh]): This is a set statement, 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[] argsthrows 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($list = ["Ajay""Bhanu""Komal""Shuki""Rakesh"]

$list

Output:
[Ajay, Bhanu, Komal, Shuki, Rakesh]
