inner classes instances in java

What are the inner classes in Java?
An inner class in Java is defined as a class that is declared inside another class.
Inner classes are often used to create helper classes, such as views or adapters that are used by the outer class.
Inner classes can also be used to create nested data structures, such as a linked list.
Inner classes are used primarily to implement helper classes like the one shown in this example.
If you plan on handling user-interface events, you'll need to know about using inner classes because the event-handling mechanism makes extensive use of them.

How are inner classes compiled in Java?

Inner class code is typically defined relative to some enclosing class instance, so the inner class instance needs to be able to determine the enclosing instance.
The JavaSoft Java 1.1 compiler arranges this by adding an extra private instance variable which links the inner class to the enclosing class.

Can I have a class inside another class in Java?

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.

Inner Classes As with instance methods and variables, an inner class is associated with an instance of its enclosing class and has direct access to that object's methods and fields. Also, because an inner class is associated with an instance, it cannot define any static members itself.
