Section 1: Java Basics

Item 1: Define the scope of variables.

Item 2: Define the structure of a Java class.

Item 3: Create executable Java applications with a main method; run a Java program from the command line; produce console output.

Item 4: Import other Java packages to make them accessible in your code.

Item 5: Compare and contrast the features and components of Java such as: platform independence, object orientation, encapsulation, etc.

Section 2: Working with Java Data Types

Item 1: Declare and initialize variables (including casting of primitive data types).

Item 2: Differentiate between object reference variables and primitive variables.

Item 3: Know how to read or write to object fields.

Item 4: Explain an object's lifecycle (creation, "dereference by reassignment" and garbage collection).

Section 3: Using Operators and Decision Constructs

Item 1: Use Java operators; use parentheses to override operator precedence.

Item 2: Test equality between strings and other objects using == and equals\(\) .

Item 3: Create and use if , if - else , and ternary constructs.

Item 4: Use a switch statement.

Section 4: Creating and Using Arrays

Item 4: Compare loop constructs.

Item 5: Use break and continue .

Section 6: Working with Methods and Encapsulation

Item 1: Create methods with arguments and return values, including overloaded methods.

Item 2: Apply the static keyword to methods and fields.

Item 3: Create an overloaded method; differentiate between default and user defined constructors.

Item 4: Apply access modifiers.

Item 5: Apply encapsulation principles to a class.

Item 6: Determine the effect upon object references and primitive values when they are passed into methods that change the values.

Section 7: Working with Inheritance

Item 1: Describe inheritance and its benefits.

Item 2: Develop code that makes use of polymorphism; develop code that overrides methods; differentiate between the type of a reference and the type of an object.

Item 3: Determine when casting is necessary.

Item 4: Use super and this to access objects and constructors.

Item 5: Use abstract classes and interfaces.

Section 8: Handling Exceptions

Item 1: Differentiate among checked exceptions, RuntimeException , and Error .

Item 2: Create a try\-catch block and determine how exceptions alter normal program flow.

Item 3: Describe the advantages of exception handling .

Item 4: Create and invoke a method that throws an exception.

Item 5: Recognize common exception classes and categories (such as NullPointerException, ArithmeticException, ArrayIndexOutOfBoundsException, ClassCastException).

Section 9: Working with Selected classes from the Java API

Item 1: Manipulate data using the StringBuilder class and its methods.

Item 2: Create and manipulate strings.

Item 3: Create and manipulate calendar data using classes from java\.time\.LocalDateTime , java\.time\.LocalDate , java\.time\.LocalTime , java\.time\.format\.DateTimeFormatter , java\.time\.Period .

Item 4: Declare and use an ArrayList of a given type.

Item 5: Write a simple Lambda expression that consumes a Lambda Predicate expression.
