Here, we are creating an object of thestatic nested classby simply using the class name of the outer class. Hence, the outer class cannot be referenced usingOuterClass.this. Example 3: Static Inner Class classMotherBoard{// static nested classstaticclassUSB{intusb2 =2;intusb3 =1;intgetTo...
Like regular classes, static nested classes can include both static and non-static fields and methods. For example, Class Animal {staticclassMammal{// static and non-static members of Mammal}// members of Animal} Static nested classes are associated with the outer class. To access the static ...
ExampleGet your own Java Server class OuterClass { int x = 10; class InnerClass { int y = 5; } } public class Main { public static void main(String[] args) { OuterClass myOuter = new OuterClass(); OuterClass.InnerClass myInner = myOuter.new InnerClass(); System.out.println(my...
new InnerClass(); 内部类有两种类型:局部类(local classes) 和 匿名类(anonymous classes). 局部类-Local Classes 局部类是一种被定义在代码块中的类,局部类通常时定义在方法体中。 如何声明局部类: 可以在任何一个方法之中定义一个局部类,如for循环中,或者在if子句中。 下面的LocalClassExample,是用来验证...
Static nested classes are accessed using the enclosing class name: OuterClass.StaticNestedClass For example, to create an object for the static nested class, use this syntax: OuterClass.StaticNestedClass nestedObject =new OuterClass.StaticNestedClass(); ...
静态嵌套类-Static Nested Classes 静态嵌套类不能直接引用外部基类的实例变量和实例方法,对于这样的实例变量仅可以通过对象引用来获取。 通过使用外围基类名称来获取静态嵌套类 OuterClass.StaticNestedClass 1. 如果我们想创建一个静态嵌套类的对象,则可以使用如下的方式 ...
a static nested class is associated with its outer class. And like static class methods, 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 Exampledemonst...
public class Red { void method2(){} } } In the example above we have Donna and Red both nested classes of Eric. Remember Eric is the top level class so it can’t be made static. So, that leaves us with Donna and Red. Eric is in love with Donna, meaning it would be wise of ...
In this case, thethiskeyword refers to the instances of the nested class and the members of the outer class can be referred to using the name of the outer class. Let’s see a quick example: publicclassNewOuter{inta=1;staticintb=2;publicclassInnerClass{inta=3;staticfinalintb=4;publicvoi...
