It also helps developers of Java tools immensely. For example, boilerplate code and configuration files can be generated based on annotations in the source code; custom annotation-based rules can be validated at compile time, etc. Annotation processing at compile time is a two-step process. First, you need to write a custom annotation processor. Second, you need to use the javac command line utility tool. You need to pass your custom annotation processor to the javac compiler using the –processor option.

Since Tire is a member inner class of the Car class, you must have an object of the Car class before you can create an object of the Tire class. The new operator is used differently to create an object of a member inner class. The “Creating Objects of Inner Class” section in this chapter explains how to create objects of an inner member class. Local Inner Class A local inner class is declared inside a block. Its scope is limited to the block in which it is declared. Since its scope is always limited to its enclosing block, its declaration cannot use any access modifiers such as public, private, or protected.

In such cases, you can combine the two statements into one statement. nextInt(); int value = (int)((n1 + n2)/2); return value; } }; } A static Member Class Is Not an Inner Class A member class defined within the body of another class may be declared static. innerclasses; public class A { // Static member class public static class B { // Body for class B goes here } } 51 CHAPTER 2 N INNER CLASSES A static member class is not an inner class.
