import java.io.StringWriter; 
import java.io.Writer; 
import java.util.Properties; 
 
import org.apache.velocity.Template; 
import org.apache.velocity.VelocityContext; 
import org.apache.velocity.app.Velocity; 
 
public class HelloWorldProperties { 
 
  public static void main(String[] args) throws Exception { 
    Properties props = new Properties(); 
    props.put("input.encoding", "utf-8"); 
 
    Velocity.init(props); 
 
    Template template = Velocity.getTemplate("./src/HelloWorld.vm"); 
 
    VelocityContext context = new VelocityContext(); 
 
    Writer writer = new StringWriter(); 
    template.merge(context, writer); 
 
    System.out.println(writer.toString()); 
  } 
}
