- 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; including console output.
- Import other Java packages to make them accessible in your code
- NEW - 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)
- NEW - Develop code that uses wrapper classes such as Boolean, Double,
and Integer.
- Using Operators and Decision Constructs
- Use Java operators; including parentheses to override operator precedence
(3.1 + 3.2)
- 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 array
- 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 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; including impact on default 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
- Working with Inheritance
- Describe inheritance and its benefits
- Develop code that demonstrates the use of polymorphism; including
overriding and object type versus reference type
- 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
,
ArithmeticExcpetion
, ArrayIndexOutOfBoundsException
,
ClassCastException
)
- Working with Selected classes from the Java API
- Manipulate data using the
StringBuilder
class and its methods
- Creating and manipulating 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
