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")
