Java 2™ Programmer Exam Cram™ 2 (Exam CX-310-035)

Introduction

Classes are the core concept of the Java language. Because all programming in Java consists of defining classes, it is essential to understand how to create a class. Points that are likely to arise in exam questions include the visibility of methods and variables in a class and other program elements as controlled by access modifier keywords. You should also clearly understand the differences between instance variables, static variables, and local variables declared inside code blocks.
