--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
--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
--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
--Write code that makes proper use of exceptions and exception handling
clauses (try, catch, finally) and declares methods and overriding methods that
■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
--State the range of all primitive data types and declare literal values for
String and all primitive types using all permitted formats, bases, and
■Section 5 Operators and assignments
--Determine the result of applying any operator, including assignment
operators, instanceof, 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,
--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
■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"
--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
■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 GUI 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, 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
■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
--Select valid constructor arguments for FilterInputStream and F
ilterOutputStream subclasses from a list of classes in the java.io.package.
--Write appropriate code to read, write and update files using F
ileInputStream, FileOutputStream, and RandomAccessFile objects.
--Describe the permanent effects on the file system of constructing and using
FileInputStream, FileOutputStream, and RandomAccessFile objects.
