The utility classes in an application are wehre we write static classes to put common functionality and call those utilities without creating objects. System.Math is an example of static class when we call the method of Math classe. We don’t use Math object we directly use Math.Add(). In the application we can create common reusable functionality and call it without creating objects .

Hi A static class is basically the same as a non-static class but there is one difference: a static class cannot be instantiated. In other words you cannot use the new keyword to create a variable of the class type. Because there is no instance variable you access the members of a static class by using the class name itself.
