in javadoc tags are not working

Java

I am using TextPad and when I am generating javadoc it shows the description
but it doesn't show me the tag which I am using .

/**  @author  Vivek */
public class DemoClass
{

    public static void main(String a[])
    {
        System.out.println("Hi !! This is author here");
    }

    /** Its gettig the name of person*/
    public void getName(String name)
    {

    }
}

here i can see lines of getName method but not author name
