Chapter4 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 expllicit 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

Chapter5 Operators and Assignments

Determine the result of applying and 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 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 object and primitive values of passing variables into methods and performing assignments or other modifying operations in that method

Chapter6 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 relationshops"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
