Use if else and end statements in velocity

This Example shows you how
to Use if 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 object of VelocityContext class 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....." otherwise 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/ifelse.vm");
VelocityContext context = new VelocityContext();
Writer writer = new StringWriter();
template.merge(context, writer);
System.out.println(writer);
}

ifelse.vm
#set($name ="komal")
