A static nested class in Java serves a great advantage to namespace resolution. This is the basic idea behind introducing static nested classes in Java. For example, if you have a class with an exceedingly common name, and in a large project, it is quite possible that some other programmer...
1、内部类的外嵌类的成员变量在内部类中任然有效,内部类中的方法也可以调用外嵌类中的 方法,内部类中不可以声明类的变量和方法,外嵌的类体可以用内部类声明对象,作为外嵌类的成员。内部类仅供他的外嵌类使用。 package com.Example1; public class Example7_1 { public static void main(String[]...猜...
a static nested class cannot refer directly to instance variables or methods defined in its enclosing class: it can use them only through an object reference.Inner Class and Nested Static Class Exampledemonstrates this.
In Java, you can define a class within another class. Such class is known asnested class. For example, classOuterClass{// ...classNestedClass{// ...} } There are two types of nested classes you can create in Java. Non-static nested class (inner class) ...
For example:C# 复制 class NLog { // Private Constructor: private NLog() { } public static double e = Math.E; //2.71828... } The declaration of the empty constructor prevents the automatic generation of a parameterless constructor. If you don't specify an access modifier f...

So, an inner classcan directly access its outer class members, but can not have static members itself. Instances of an inner class only exist within an instance of its outer class. For example View Code reference from:https://docs.oracle.com/javase/tutorial/java/javaOO/nested.html...
