 Template Engines > Velocity > If Else

If Else 

Apache Velocity is a free, simple and powerful template engine written in 100% pure Java. This requires the libraries velocity-1.7.jar, oro-2.0.8.jar, commons-lang-2.4.jar, commons-collections-3.2.1.jar, commons-logging-1.1.jar, log4j-1.2.12.jar to be in classpath. The following example shows using if else block in Velocity.

package com.bethecoder.tutorials.velocity.tests;

import java.io.StringWriter;

import org.apache.velocity.Template;
import org.apache.velocity.VelocityContext;
import org.apache.velocity.app.VelocityEngine;
import org.apache.velocity.runtime.RuntimeConstants;
import org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader;

public class IfElseTest {

  /**
   @param args
   */
  public static void main(String[] args)  {

    /**
     * Initialize engine and get template
     */
    VelocityEngine ve = new VelocityEngine();
    ve.setProperty(RuntimeConstants.RESOURCE_LOADER, "classpath")
    ve.setProperty("classpath.resource.loader.class", ClasspathResourceLoader.class.getName());
        Template template = ve.getTemplate("ifelse.vm");
        
        /**
         * Prepare context data
         */
        VelocityContext context = new VelocityContext();

        /**
         * Merge data and template
         */
        StringWriter swOut = new StringWriter();
        template.merge(context, swOut);
        
        System.out.println(swOut);
  }
}
   

It gives the following output,

	Loan is on hold	
	


                    Print
