Objects
String class
Primitive Data
I/O |
Simple data types (int, boolean, double, char); declarations (variable and constant); assignment and arithmetic expressions; console output (System.out.print/println); primitive types vs. objects; using classes to create objects; references; Java library classes (String, Integer, Double, Math, Scanner); and creating random numbers. |

|
Data structures |
1D, 2D arrays creation, insertions, deletions, traversals, algorithms |
|
|
|
Searching through data structures
Use logical operators to make programs more robust
Construct truth tables
Sorting data |
Search and comparison algorithms (sequential and binary); choosing appropriate data representation and sorting algorithms (selection, merge, and insertion sorts) |
control statements, counter, infinite loop, iteration, nested loops, logical operators, truth tables
|
|
|
LOOPING and CONDITIONALS
Conditional Program Statements
Sequential & conditional decision-making processes
Boolean expressions |
Software Development Process; control flow (sequential and conditional); Boolean expressions, laws, and truth tables; using conditional expressions in if, if-else, and nested if statements; and More operators (increment, decrement, compound assignment). |
Declaring and initializing arrays
• Manipulating arrays with loops
• Creating parallel arrays |
|
|
Iterative program statements
Loops and controls
|
Flow of control (iteration); using while and for statements; infinite and nested loops; |
Manipulate arrays using loops and array indices • Use the physical and logical size of an array together to guarantee they do not go beyond the bounds of their array by identifying the boundary cases and using test data to verify results • Understand how parallel arrays can be useful when processing certain types of data • Work with arrays of primitive data types as well as arrays of objects while understanding the difference between the two types of data • Understand when to choose an array to represent data instead of an ArrayList |
|
Basic analysis of algorithms |
Informal comparison and discussion of running times and exact calculation of statement execution counts. |
|
|
|
Ethical and social implications of Computer use |
The responsible use of computer systems (system reliability, privacy, intellectual property, legal issues, and social and ethical ramifications of computer use. |

Write classes and subclasses that implement an interface.
|
Interfaces |
Write an Eatable interface-
public String howToEat(); public void showObject(); |
|
|
|
interfaces and abstract classes; Java library classes (Object); reading and understanding class specifications and relationships among classes (“is-a” and “has-a”); understanding and implementing a given class hierarchy; extending a given class using inheritance; and applying functional decomposition. |
Design and create a class called Animal, with subclasses Tiger, Chicken, and Elephant. Since chicken is eatable, implement the Eatable interface for the Chicken class. Create a class called Fruit, with subclasses Apple and Orange. Since all fruits are eatable, implement the Eatable interface for the Fruit class. |
