/* Why there is no static constructor in Java. In fact, Java is not called static constructors, called static initialization, or static code blocks. * This code can be used to achieve t

When class initialization is considered, we all know that when subclasses are initialized, subclasses are initialized if the parent class is not initialized. But there is no such thing as a simple word.First look at the conditions in Java that initialize the trigger: (1) When the object is instantiated using new, the
