In Java, it is also possible to nest classes (a class within a class). The purpose of nested classes is to group classes that belong together, which makes your code more readable and maintainable.To access the inner class, create an object of the outer class, and then create an object ...

In Java, we can also define astaticclass inside another class. Such class is known asstatic nested class. Static nested classes are not called static inner classes. Unlike inner class, a static nested class cannot access the membervariablesof the outer class. It is because thestatic nested cl...
Java允许在一个类的内部定义一个类,这样的类称为嵌套类。例: class OuterClass { ... class NestedClass { ... } } 嵌套类分为两类:静态和非静态。 用static 修饰的嵌套类称为静态嵌套类,未使用static修饰的嵌套类称为内部类。 class OuterClass { ... static class StaticNestedClass { ... } clas...
1. Static Nested Class (Very Different from C# static class) alpha: Have access to all the static members of its parent class. beta: Can instantiate objects by new ParentClass.StaticNestClass(). Now allowed to create objects in C#.
在Java中我们可以在一个类的内部,再定义另外一个类,其中里面的那个类被称为嵌套类,示例如下。 1 2 3 4 5 6 class OuterClass { ... class NestedClass { ... } } 术语:嵌套类有两种类型:静态和非静态,当嵌套类被static修饰时,被称为静态嵌套类(static nested classes),没有被static修饰时的嵌套类被...

Also, you might have noticed how we had never made our top level class as static. The reason is plain and simple. Because in Java it can’t be done! Only a class that is nested can be turned into a static class in Java. That being said we must understand that using static classes...
