Exam Objectives |
|
| |
|
| Section 1:
Declarations and Access Control |
|
| |
- Write code that declares, constructs, and
initializes arrays of any base type using any of the permitted forms
both for declaration and for initialization.
- Declare classes, inner classes, methods, instance
variables, static variables, and automatic (method local) variables
making appropriate use of all permitted modifiers (such as public,
final, static, abstract, and so forth).
- 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.
- For a given class, determine if a default
constructor will be created, and if so, state the prototype of that
constructor.
- State the legal return types for any method given
the declarations of all related methods in this or parent classes.
|
| |
| Section 2: Flow
Control and Exception Handling |
|
| |
- Write code using if and switch statements and
identify legal argument types for these statements.
- Write code using all forms of loops including
labeled and unlabeled use of break and continue, and state the
values taken by loop control variables during and after loop
execution.
- 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 3: Garbage
Collection |
|
| |
- State the behavior that is guaranteed by the
garbage collection system, and write code that explicitly makes
objects eligible for collection.
|
| |
| Section 4:
Language Fundamentals |
|
| |
- Identify correctly constructed source files,
package declarations, import statements, class declarations (of all
forms including inner classes), interface declarations and
implementations (for java.lang.Runnable or other interface described
in the test), method declarations (including the main method that is
used to start execution of a class), variable declarations and
identifiers.
- 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
and correctly constructed identifiers.
- State the effect of using a variable or array
element of any kind when no explicit assignment has been made to it.
- State the range of all primitive data types and
declare literal values for String and all primitive types using all
permitted formats, bases, and representations.
|
| |
| Section 5:
Operators and Assignments |
|
| |
- Determine the result of applying any operator,
including assignment operators, instance of, and casts 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.
- 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, inner classes, static
inner classes, and anonymous inner classes.
|
| |
| Section 7: Threads |
|
| |
- Write code to define, instantiate, and start new
threads using both java.lang.Thread and java.lang.Runnable.
- Recognize conditions that might prevent a thread
from executing.
- Write code using synchronized, wait, notify, or
notifyAll, to protect against concurrent access problems and to
communicate between threads.
- Define the interaction between threads and between
threads and object locks when executing synchronized, wait, notify,
or notifyAll.
|
| |
| Section 8: The
java.awt Package |
|
| |
- Write code using component, container, and
LayoutManager classes of the java.awt package to present a Graphical
User Interface with specified appearance and resize behavior, and
distinguish the responsibilities of layout managers from those of
containers.
- Write code to implement listener classes and
methods, and in listener methods, extract information from the event
to determine the affected component, mouse position, nature, and
time of the event.
- State the event classname for any specified event
listener interface in the java.awt.event package.
|
| |
| Section 9: 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, and sqrt.
- Describe the significance of the immutability of
string objects.
|
| |
| Section 10: The
java.util Package |
|
| |
- Make appropriate selection of collection
classes/interfaces to suit specified behavior requirements.
|
| |
| Section 11: The
java.io Package |
|
| |
- Write code that uses objects of the file class to
navigate a file system.
- Write code that uses objects of the classes
InputStreamReader and outputStreamWriter to translate between
Unicode and either platform default or ISO 8859-1 character encoding
and Distinguish between conditions under which platform default
encoding conversion should be used and conditions under which a
specific conversion should be used.
- Select valid constructor arguments for
FilterInputStream and FilterOutputStream subclasses from a list of
classes in the java.io.package.
- Write appropriate code to read, write and update
files using FileInputStream, FileOutputStream, and RandomAccessFile
objects.
- Describe the permanent effects on the file system
of constructing and using FileInputStream, FileOutputStream, and
RandomAccessFile objects.
