inetaddress**********************For InetAddress, three methods: Getlocalhost (), Getbyname (), and Getallbyname () can be used to create instances of inetaddress.　The InetAddress class does not provide a return constructor, so the new () method cannot be used to create its object, but only static methods Getlocalhost (), Getbyname (), getbyaddress () can be called. And so on to generate the essence of the InetAddress

Sealing Class and Class Members, sealing class members // The sealed class cannot be used as the base Class. do not derive public sealed class B {// Class members here .} // when a der

The base class baseoutput explicitly inherits an interface ioutput, and the class trackoutput inherits baseoutput, and also inherits the ioutput interface. Assume that ioutput has a method output, so there are two output methods in trackoutput, one source is the base class baseoutput and the other source is the interface ioutput. This leads to confusion. What sho

Today, I saw several concepts in the Code: internal class, local class, member class, static member class, and anonymous internal class. I felt confused in an instant. Below is a small example to illustrate them: Public class cla

When a class is loaded, its inner class is loaded at the same time. Now let's do an experiment to see. Java Code publicclassouter{ static{ NBSP;NBSP;NBSP;NBSP;NBSP;NBSP;NBSP;NBSP;SYSTEM.OUT.PRINTLN ("Loadouterclass ..."); } / /static internal class staticclassStaticInner{ static{ system.out.println ("Loadstaticinnerclass ..."); } staticvoidstaticinnerm

In C ++, what is the difference between Class A and Class * A = new class? In C ++Class;A. Run ();AndClass A = new class ();A. Run ();Are there any differences between the two? Yes What is the difference? Class A = new

If JAVA wants to make the class unable to be new, it can use private to change the class constructor to private. In this way, an error will be reported when the class is new. The private constructor If JAVA wants to make the class unable to be new, it can use private to change the constructor to private so that an err
