The Sun Certified Associate for the Java Platform, Standard Edition, Exam Version 1.0 This certification exam provides an ideal entry into an application development or a software project management career using Java technologies. This worldwide credential validates basic knowledge of Object Oriented Concepts, UML representation of OO concepts, the Java programming language, and general knowledge of Java Platforms and Technologies. Candidates for this exam include: entry level Java programmers, students studying to become Java programmers, project or program managers working with Java technology in the software development industry. The Sun Certified Programmer for Java 2 Platform 5.0 This certification exam is for programmers experienced using the Java programming language. Achieving this certification provides clear evidence that a programmer understands the basic syntax and structure of the Java programming language and can create Java technology applications that run on server and desktop systems using J2SE 5.0. Sun Certified Developer for the Java 2 Platform, Standard Edition This certification is in two parts. Part 1 Developer Assignment The assignment requires that you write working code for a small but plausible business system. To keep the amount of work involved to a reasonable level, the programs you create will be much more restricted in capability, and much cruder in overall presentation, than anything you would actually create for a paying customer. However, the essence of the problem will be the same. You will be graded on correctly solving the technical requirements, not on the "polish" of the finished product. Note however, that some aspects of ease of use, for example how easily the program may be started or configured, will be part of the scoring criteria. Pay careful attention to any such requirements and be sure to adhere to them. Part 2 certification exam The certification exam is for programmers who are already familiar with the basic structure and syntax of the Java programming language, and who have a need to further apply this knowledge
2 to developing complex, production level applications. Certification is available for the Java 2 platform. Sun Certified Web Component Developer The Sun Certified Web Component Developer for J2EE Platform certification exam is for Sun Certified Programmers (any edition) who are using the Java technology servlet and JavaServer Pages (JSP) application program interface (APIs) to develop Web applications. Sun Certified Business Component Developer The Sun Certified Business Component Developer for the Java 2 Platform, Enterprise Edition 1.3 exam is for programmers and developers who are responsible for designing, developing, testing, deploying, and integrating Enterprise JavaBeans (EJB) applications. It is also for those specializing in leveraging the Java 2 Platform, Enterprise Edition (J2EE platform) technologies used to develop server side components that encapsulate the business logic of an application. Prior to beginning the Sun Certified Business Component Developer program, you must be a Sun Certified Programmer for the Java platform (any edition). Sun Certified Developer for Java Web Services The Sun Certified Developer for Java Web Services certification exam is for developers who have been creating web services applications using Java technology components such as those supported by the Java Web Services Developer Pack and the Java 2, Enterprise Edition 1.4 platform. Passing this exam certifies that the candidate has achieved a standard level of proficiency with web services, as well as with the Java technologies that support web services. Sun Certified Enterprise Architect This exam is in 3 parts. Part 1 is multiple choice and tests your knowledge in the areas of general architecture and J2EE. Part 2 is an assignment that tests your ability to apply the knowledge you were tested on in part 1. Part 3 is an essay that asks questions about your assignment.
3 Scoring Criteria for the Architect Exam Your project will be evaluated on a large number of objective criteria that fall into three categories: 1) Class Diagram: This category covers how well your class diagram(s) address the object model needed to satisfy the requirements. 2) Component Diagram: This category covers how well your component diagram(s) convey the structure of the architecture in satisfying the requirements. 3) Sequence/Collaboration Diagrams: This category covers how well your sequence or collaboration diagrams satisfy the requirements of the assignment. Additionally, each category is evaluated on UML compliance. The maximum number of possible points is 100. The minimum passing grade is 70. Sun Certified Mobile Application Developer The Sun Certified Mobile Application Developer for the Java 2 Platform, Micro Edition, Version 1.0 certification exam is for programmers and developers who are using Java 2 Platform, Micro Edition (J2ME) technologies to develop mobile applications for cell phones or other Java enabled devices.

Recognize situations that will result in any of the following being thrown: ArrayIndexOutOfBoundsException,ClassCastException, IllegalArgumentException, IllegalStateException, NullPointerException, NumberFormatException, AssertionError, ExceptionInInitializerError, StackOverflowError or NoClassDefFoundError. Understand which of these are thrown by the virtual machine and recognize situations in which others should be thrown programatically. Section 3: API Contents Develop code that uses the primitive wrapper classes (such as Boolean, Character, Double, Integer, etc.), and/or autoboxing & unboxing. Discuss the differences between the String, StringBuilder, and StringBuffer classes. Given a scenario involving navigating file systems, reading from files, or writing to files, develop the correct solution using the following classes (sometimes in combination), from java.io: BufferedReader,BufferedWriter, File, FileReader, FileWriter and PrintWriter. Develop code that serializes and/or de serializes objects using the following APIs from java.io: DataInputStream, DataOutputStream, FileInputStream, FileOutputStream, ObjectInputStream, ObjectOutputStream and Serializable. Use standard J2SE APIs in the java.text package to correctly format or parse dates, numbers, and currency values for a specific locale; and, given a scenario, determine the appropriate methods to use if you want to use the default locale or a specific locale. Describe the purpose and use of the java.util.locale class.
8 Write code that uses standard J2SE APIs in the java.util and java.util.regex packages to format or parse strings or streams. For strings, write code that uses the Pattern and Matcher classes and the String.split method. Recognize and use regular expression patterns for matching (limited to:. (dot), * (star), + (plus),?, \d, \s, \w, , ()). The use of *, +, and? will be limited to greedy quantifiers, and the parenthesis operator will only be used as a grouping mechanism, not for capturing content during matching. For streams, write code using the Formatter and Scanner classes and the PrintWriter.format/printf methods. Recognize and use formatting parameters (limited to: %b, %c, %d, %f, %s) in format strings. Section 4: Concurrency Write code to define, instantiate, and start new threads using both java.lang.thread and java.lang.runnable. Recognize the states in which a thread can exist, and identify ways in which a thread can transition from one state to another. Given a scenario, write code that makes appropriate use of object locking to protect static or instance variables from concurrent access problems. Given a scenario, write code that makes appropriate use of wait, notify, or notifyall. Section 5: OO Concepts Develop code that implements tight encapsulation, loose coupling, and high cohesion in classes, and describe the benefits. Given a scenario, develop code that demonstrates the use of polymorphism. Further, determine when casting will be necessary and recognize compiler vs. runtime errors related to object reference casting. Explain the effect of modifiers on inheritance with respect to constructors, instance or static variables, and instance or static methods. Given a scenario, develop code that declares and/or invokes overridden or overloaded methods and code that declares and/or invokes superclass, overridden, or overloaded constructors. Develop code that implements "is a" and/or "has a" relationships. Section 6: Collections / Generics Given a design scenario, determine which collection classes and/or interfaces should be used to properly implement that design, including the use of the Comparable interface. Distinguish between correct and incorrect overrides of corresponding hashcode and equals methods, and explain the difference between == and the equals method. Write code that uses the generic versions of the Collections API, in particular, the Set, List, and Map interfaces and implementation classes. Recognize the limitations of the non generic Collections API and how to refactor code to use the generic versions.
9 Develop code that makes proper use of type parameters in class/interface declarations, instance variables, method arguments, and return types; and write generic methods or methods that make use of wildcard types and understand the similarities and differences between these two approaches. Use capabilities in the java.util package to write code to manipulate a list by sorting, performing a binary search, or converting the list to an array. Use capabilities in the java.util package to write code to manipulate an array by sorting, performing a binary search, or converting the array to a list. Use the java.util.comparator and java.lang.comparable interfaces to affect the sorting of lists and arrays. Furthermore, recognize the effect of the "natural ordering" of primitive wrapper classes and java.lang.string on sorting. Section 7: Fundamentals Given a code example and a scenario, write code that uses the appropriate access modifiers, package declarations, and import statements to interact with (through access or inheritance) the code in the example. Given an example of a class and a command line, determine the expected runtime behavior. Determine the effect upon object references and primitive values when they are passed into methods that perform assignments or other modifying operations on the parameters. Given a code example, recognize the point at which an object becomes eligible for garbage collection, and determine what is and is not guaranteed by the garbage collection system. Recognize the behaviors of System.gc and finalization. Given the fully qualified name of a class that is deployed inside and/or outside a JAR file, construct the appropriate directory structure for that class. Given a code example and a classpath, determine whether the classpath will allow the code to compile successfully. Write code that correctly applies the appropriate operators including assignment operators (limited to: =, +=, =), arithmetic operators (limited to: +,, *, /, %, ++, ), relational operators (limited to: <, <=, >, >=, ==,!=), the instanceof operator, logical operators (limited to: &,, ^,!, &&, ), and the conditional operator (? : ), to produce a desired result. Write code that determines the equality of two objects or two primitives.
