I. Basic data type Object type1, first think of a question, after having the basic type why should there be a wrapper type?Core: Let the basic type have the characteristics of the object, to achieve more functions.Java is the programming language of

Java class loading takes a full-fledged delegation mechanism, and the subclass will delegate to the parent class when the class is loaded by default, but the subclass will attempt to load the class itself when the parent class is not loaded. This

When writing a window program with a consistent change in Java, the usual approach is to overwrite the parent class's Paint (Graphics) method in the subclass and use the GUI function in the method to redraw the window. The window of a coherent
