2. Work with data types, variables, and expressions (40-45%)
Declare and use primitive data type variables
- data types, including byte, char, int, double, short, long, float, boolean; identify when precision is lost; initialization; how primitives differ from wrapper object types such as Integer and Boolean

Construct and evaluate code that creates, iterates, and manipulates arrays and array lists - one- and two-dimensional arrays, including initialization, null, size, iterating elements, accessing elements; array lists, including adding and removing elements, traversing the list
Construct and evaluate code that performs parsing, casting and conversion
- implementing code that casts between primitive data types, converts primitive types to equivalent object types, or parses strings to numbers
Construct and evaluate arithmetic expressions
- arithmetic operators, assignment, compound assignment operators, operator precedence
3. Implement flow control (15-20%)
Construct and evaluate code that uses branching statements
- if, else, else if, switch; single-line versus block; nesting; logical and relational operators
Construct and evaluate code that uses loops
- while, for, for each, do while; break and continue; nesting; logical, relational, and unary operators
4. Perform object-oriented programming (10-15%)
Construct and evaluate a class definition
- constructors; constructor overloading; one class per .java file; this keyword; inheritance and overriding at a basic level
Declare, implement, and access data members in a class
- private, public, protected; instance data members; static data members; using static final to create constants; describe encapsulation
Declare, implement, and access methods
- private, public, protected; method parameters; return type; void; return value; instance methods; static methods; overloading
Instantiate and use a class object in a program
- instantiation; initialization; null; accessing and modifying data members; accessing methods; accessing and modifying static members; importing packages and classes
5. Compile and debug code (5-10%)
Troubleshoot syntax errors, logic errors, and runtime errors
- print statement debugging; output from the javac command; analyzing code for logic errors; console exceptions after running the program; evaluating a stack trace
