== Define and use variable in Velocity ==



<source lang="java">

import java.io.StringWriter;
import java.io.Writer;

public class VMDemo {
public static void main(String[] args) throws Exception {
Velocity.init();
Template t = Velocity.getTemplate("./src/VMDemo.vm");
VelocityContext ctx = new VelocityContext();
Writer writer = new StringWriter();
t.merge(ctx, writer);
System.out.println(writer);
}
}
-------------------------------------------------------------------------------------
#set ($a = 13)
#set ($b = 14)
#set ($c = $a * $b)
$c
