Does C # and java have static type support?

Question

I used the Singleton classes and the static method for a while and always wondered how nice it would be to have a separate type, which is a static type and cannot be created, but only has static methods!

It will be easy to read and also support.

for ex

public UtilType MyUtility
{
  public void Calculate(int x,int y)
  {
    return x+y;
  }
}

It MyUtilityshould not be stated here that only its methods can be accessed in a static way.
