Data Type: bool

This Example shows you how to use bool datatype in velocity.

Data Type: bool

Data Type: bool

     

This Example shows you how to use bool datatype in velocity. Methods 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($bool = true): Set a boolean datatype variable.

$bool: Display boolean datatype variable.

 

  DataTypeBool.java

import java.io.*;

import org.apache.velocity.*;
import org.apache.velocity.app.*;
import org.apache.velocity.tools.generic.RenderTool;

public class DataTypeBool {

  public static void main(String[] args) throws Exception {
  Velocity.init();
  Template template = Velocity.getTemplate("./src/DataTypeBool.vm");

  VelocityContext context = new VelocityContext();

  Writer writer = new StringWriter();
  template.merge(context, writer);

  System.out.println(writer);
  }
}

DataTypeBool.vm
#set($bool = true)

$bool

Output:
true
