Today, a person in the group raised an internal class question. Although I have seen it before, it cannot solve his problem. Now I want to organize it: Public class Outer {Inner in = new inner ();Public static void main (string [] ARGs ){New outer ();System. Out. println ("this is main .");}Class inner extends outer {}} This is the program he gave. After I try it, the following error will be reported during compilation: exception in thread "Main" Java

Understand the. this and. new syntaxes of java-8.3 internal classes from the beginning In this section, we will talk about the. this and. new syntaxes of internal classes. In fact, the above is a bit of a problem. The correct statement is the external Class Object. this and the external Class Object. new. Example: Package com. ray. ch03; public class Test {

{System.out.println ("Cre ating new Cupboard () in main "); New Cupboard (); System.out.println ("Creating New Cupboard () in main"); New Cupboard (); T2.F2 (1); T3.F3 (1); } static Table t2 = new Table (); static cupboard T3 = new cupboard ();} 1. Start running, the JVM loads the test class first, then initializes the static member variable T2, T32. Then load the table class and initialize the class static member variable B1, B2, call the bowl constructo

constructor written in this class. This constructor is qualified with the public access modifier, has no formal parameters, and does nothing. The default constructor still follows the rules of the constructor.If we write one or more constructors for a class, then the system will not generate the default constructor in the build.5. Constructor Invocation Method:When an object instantiates an object using the keyword new, the constructor is called. One

Javac compilation can be optimized for expressions that add directly to string constants, only one object is created.Does 8.String polygon amount automatically generate a string object?Is that the string class has a certain particularity, when the JVM executes the double quote operator, it automatically creates a string object and returns a reference to the object.9. What is the role of a string object pool?Object pooling exists to avoid the frequent
