  四、考试大纲
  1、DECLARATIONS AND access CONTROL
  1、Write code that declares, constructs, and initializes arrays of any base type using any of the permitted FORMs both for declaration and for initialization
  2、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)
  3、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
  4、For a given class, determine if a default constructor will be created, and if so, state the prototype of that constructor
  5、State the legal return types for any method given the declarations of all related methods in this or parent classes
  2、FLOW CONTROL AND EXCEPTION HANDLING
  1、Write code using if and switch statements and identify legal argument types for these statements
  2、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
  3、Write code that makes proper use of exceptions and exception handling clauses (try, catch, finally) and declares methods and overriding methods that throw exceptions
  3、GARBAGE COLLECTION
  1、State the behavior that is guaranteed by the garbage collection system, and write code that eXPlicitly makes objects eligible for collection
  4、LANGUAGE FUNDAMENTALS
  1、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
  2、State the correspondence between index values in the argument array passed to a main method and command line arguments
  3、Identify all Java programming language keyWords and correctly constructed identifiers
  4、State the effect of using a variable or array element of any kind when no explicit assignment has been made to it
  5、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

  3、In an expression involving the operators &, , &&, , and variables of known values, state which operands are evaluated and the value of the expression
  4、Determine the effect upon objects and primitive values of passing variables into methods and perFORMing assignments or other modifying operations in that method
  6、OVERLOADING, OVERRIDING, RUNTIME TYPE, AND OBJECT ORIENTATION
