Java Basics

• Define the scope of variables

• Define the structure of a Java class

• Create executable Java applications with a main method; run a Java program from the command line; produce console output

• Import other Java packages to make them accessible in your code

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

Working With Java Data Types

• Declare and initialize variables (including casting of primitive data types)

• Differentiate between object reference variables and primitive variables

• Know how to read or write to object fields

• Explain an Object's Lifecycle (creation, "dereference by reassignment" and garbage collection)

• Develop code that uses wrapper classes such as Boolean, Double, and Integer

Using Operators and Decision Constructs

• Use Java operators; use parentheses to override operator precedence

• Test equality between Strings and other objects using == and equals ()

• Create if and if/else and ternary constructs

• Use a switch statement

Creating and Using Arrays

• Declare, instantiate, initialize and use a one-dimensional array

• Declare, instantiate, initialize and use multi-dimensional arrays

Using Operators and Decision Constructs

• Use Java operators; use parentheses to override operator precedence

• Test equality between Strings and other objects using == and equals ()

• Create if and if/else and ternary constructs

• Use a switch statement

Working with Methods and Encapsulation

• Create methods with arguments and return values; including overloaded methods

• Apply the static keyword to methods and fields

• Create and overload constructors; differentiate between default and user defined constructors

• Apply access modifiers

• Apply encapsulation principles to a class

• Determine the effect upon object references and primitive values when they are passed into methods that change the values

Using Loop Constructs

• Create and use while loops

• Create and use for loops including the enhanced for loop

• Create and use do/while loops

• Compare loop constructs

• Use break and continue

Working with Inheritance

• Describe inheritance and its benefits

• 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

• Determine when casting is necessary

• Use super and this to access objects and constructors

• Use abstract classes and interfaces

Handling Exceptions

• Differentiate among checked exceptions, unchecked exceptions, and Errors

• Create a try-catch block and determine how exceptions alter normal program flow

• Describe the advantages of Exception handling

• Create and invoke a method that throws an exception

• Recognize common exception classes (such as NullPointerException, ArithmeticException, ArrayIndexOutOfBoundsException, ClassCastException)

Working with Selected classes from the Java API

• Manipulate data using the StringBuilder class and its methods

• Create and manipulate Strings

• Create and manipulate calendar data using classes from java.time.LocalDateTime, java.time.LocalDate, java.time.LocalTime, java.time.format.DateTimeFormatter, java.time.Period

• Declare and use an ArrayList of a given type

• Write a simple Lambda expression that consumes a Lambda Predicate expression
