How to execute a static block for multiple times in java

I have given a task to execute static block for every 20 seconds. I have a class that consists of a static block.

public class Hello{
      static{
        System.out.println("helloo...");
      }
}

I know that static block executes when the class is loaded.

But i want to know is there any way to execute the static block for multiple times and how?

Executing a Static Block can be Achieved by using Custom Class Loader.

ClassReload.java

    Class<?> load = ClassLoader.getSystemClassLoader().loadClass("com.Hello");
//Assume Hello class is in "com" package 
        load.newInstance().toString();
        URL[] urls = { load.getProtectionDomain().getCodeSource().getLocation() };
        ClassLoader delegateParent = load.getClassLoader().getParent();
        try (URLClassLoader cl = new URLClassLoader(urls, delegateParent)) {
            Class<?> reloaded = cl.loadClass(load.getName());
            reloaded.newInstance().toString();              
            }
            }
        }
