Java static method call non-static method

As we all know, statically static methods cannot call the non-static Non-static method, which is exactly the way that the Non-static method cannot be called directly. However, you can call the object's Non-static method by passing a reference to the object into the static method. In fact, the      application of this fact is so often that we do not pay attention to it: in the main function (static method) We often create an instance of a class, and then use its drinking variable to invoke its non-static method. staticmethodtest.java//a Ststic method cannot call A Non-static method, but we can transfer A object reference, which in Clude a non-static Metho to the static method, thus, wo can call that non-static method in a indirect way.public class Sta ticmethodtest{    void Nonstaticmethod () {        System.out.println ("This is a Non-sataic method.");      static void Staticmethod (Staticmethodtest s) {       System.out.println ("This is a static method.");       S.nonstaticmethod ();    }     public static void Main (string[] args) {        staticmethodtest sobj=new staticmethodtest ();        Staticmethod (sobj);  The static method can be called directly in the main function    }}
