SECTION 1 | WHY SHOULD I GET CERTIFIED IN JAVA TECHNOLOGY?

▲

Why should I get certified in Java Technology? As one of the core enterprise technologies of the 21st century, using Java™ Technology to build applications is a critical skill for IT professionals. Consider, for example, Web services, an IT opportunity that is developing incredibly rapidly, and an area where 60% of developers expect to use Java Technology (Source: Evans Data Corp., Autumn 2002). Java Technology certification can benefit you professionally in several ways. It can: • Improve your career potential: improve opportunities for salary increases, job role changes and promotions. A recent CRN Salary Survey for the United States indicates that certified Java Technology professionals that have achieved more than one certification command on average a 14% increase in salary over their counterparts who only hold one Java Technology certification. • Enhance your professional credibility • Increase job security - More than two-thirds of certified professionals feel that technical certifications play a role in job security. • Prove to employers that your qualifications/skills are up to date

Why should my employees get certified in Java Technology? Getting your employees certified in Java Technology will improve their technical knowledge and enhance their ability to use Java Technology. In turn, this investment in your workforce can help you increase revenue and decrease costs by: • Increasing your employees’ productivity, thereby decreasing time-to-market and giving your organisation a competitive advantage • Increasing service levels and reducing the risk of system failure • Ensuring that your employees have the required skills to meet your application development needs • Standardising your criteria for recruitment and/or for promoting employees • Increasing employee satisfaction and commitment to the business – and the likelihood that they will remain in their jobs • Increasing the credibility of your staff, and your business as a whole

SECTION 3 | TYPES OF SUN JAVA TECHNOLOGY CERTIFICATION

Types of Sun Java Technology certification Sun offers 5 different Java™ Technology Certification options, each with their recommended training courses: • Sun Certified Programmer for the Java 2 Platform • Sun Certified Developer for the Java 2 Platform • Sun Certified Web Component Developer for the Java 2 Platform • Sun Certified Business Component Developer for the Java 2 Platform • Sun Certified Enterprise Architect for the Java 2 Platform The Java Technology learning path os illustrated on page 5.

Sun’s certification policy Sun operates its certification programme on the premise that candidates need only be certified once and their skills will be recognised everywhere. Consequently, Sun offers certification based on a version of technology, rather than requiring candidates to re-certify after a set period. However, to get the maximum value from certification, candidates should ensure that they are, and continue to be, certified on the most current version of the technology. When technology is updated, candidates wishing to keep their certification current may need to take the new certification exam, although upgrade exams are available for some certification titles.

Sun Certified Programmer for J2SE Exam objectives

Section 3: Garbage collection

The objectives for the Sun Certified Programmer for the Java™ 2 Platform 1.4, Standard Edition, include:

• State the behaviour that is guaranteed by the garbage-collection system.

Section 1: Declarations and access control

• Write code that explicitly makes objects eligible for garbage collection.

• Write code that declares, constructs and initialises arrays of any base type using any of the permitted forms both for declaration and for initialisation.

• Recognise, in a piece of source code, the point at which an object becomes eligible for garbage collection.

• Declare classes, nested classes, methods, instance variables, static variables and automatic (method local) variables, making appropriate use of all permitted modifiers (such as public, final, static, abstract, etc.). State the significance of each of these modifiers both singly and in combination and state the effect of package relationships on declared items qualified by these modifiers.

Section 4: Language fundamentals

• For a given class, determine if a default constructor will be created and, if so, state the prototype of that constructor. • Identify legal return types for any method, given the declarations of all related methods in this or parent classes. Section 2: Flow control, assertions, and exception handling

• Identify classes that correctly implement an interface where that interface is either java.lang.Runnable or a fully specified interface in the question. • State the correspondence between index values in the argument array passed to a main method, and command line arguments. • Identify all Java programming language keywords. Note: There will not be any questions regarding esoteric distinctions between keywords and manifest constants.

• Write code using if and switch statements, and identify legal argument types for these statements.

• State the effect of using a variable or array element of any kind when no explicit assignment has been made to it.

• Write code using all forms of loops, including labelled and unlabeled, use of break and continue, and state the values taken by loop counter variables during and after loop execution.

• State the range of all primitive formats, data types and declare literal values for String and all primitive types, using all permitted formats, bases and representations.

• Write code that makes proper use of exceptions and exception-handling clauses (try, catch, finally) and declares methods and overriding methods that throw exceptions.

Section 5: Operators and assignments

• Recognise the effect of an exception arising at a specified point in a code fragment. Note: The exception may be a runtime exception, a checked exception, or an error (the code may include try, catch, or finally clauses in any legitimate combination). • Write code that makes proper use of assertions, and distinguish appropriate from inappropriate uses of assertions. • Identify correct statements about the assertion mechanism.

Page 8 | Section 3

• Identify correctly constructed package declarations, import statements, class declarations (of all forms, including inner classes) interface declarations, method declarations (including the main method that is used to start execution of a class), variable declarations, and identifiers.

• Determine the result of applying any operator (including assignment operators and instance of) to operands of any type, class, scope, or accessibility, or any combination of these. • Determine the result of applying the Boolean equals (Object) method to objects of any combination of the classes java.lang.String, java.lang.Boolean and java.lang.Object. • In an expression involving the operators &, |, &&, || and variables of known values, state which operands are evaluated and the value of the expression.

Sun Certified Programmer for J2SE • Determine the effect upon objects and primitive values of passing variables into methods and performing assignments, or other modifying operations, in that method. Section 6: Overloading, overriding, runtime type and object orientation • State the benefits of encapsulation in object oriented design, and write code that implements tightly encapsulated classes and the relationships “is a” and “has a”. • Write code to invoke overridden or overloaded methods and parental or overloaded constructors, and describe the effect of invoking these methods. • Write code to construct instances of any concrete class, including normal top-level classes and nested classes.

Section 8: Fundamental classes in the java.lang package • Write code using the following methods of the java.lang.Math class: abs, ceil, floor, max, min, random, round, sin, cos, tan, sqrt. • Describe the significance of the immutability of String objects. • Describe the significance of wrapper classes, including making appropriate selections in the wrapper classes to suit specified behaviour requirements, stating the result of executing a fragment of code that includes an instance of one of the wrapper classes, and writing code using the following methods of the wrapper classes (e.g., Integer, Double, etc.): > doubleValue > floatValue > intValue > longValue

Section 7: Threads

> parseXxx

• Write code to define, instantiate and start new threads, using both java.lang.Thread and java.lang.Runnable.

> getXxx > toString > toHexString

• Recognise conditions that might prevent a thread from executing.

Section 9: The Collections Framework

• Write code using synchronised wait, notify and notifyAll to protect against concurrent access problems and to communicate between threads.

• Make appropriate selection of collection classes/interfaces to suit specified behaviour requirements.

• Define the interaction among threads and object locks when executing synchronised wait notify or notifyAll.
