Java Basics
Define the scope of variables
Define the structure of a Java class
Create executable Java applications with a main method
Import other Java packages to make them accessible in your code
Working With Java Data Types
Declare and initializevariables
Differentiate between object reference variables and primitive variables
Read or write to object fields
Explain an Object’s Lifecycle (creation, “dereference” and garbage collection)
Call methods on objects
Manipulate data using the StringBuilder class and its methods
Creating and manipulatingStrings
Using Operators and Decision Constructs
Use Java operators
Use parenthesis to override operator precedence
Test equality between Strings and other objects using == and equals ()
Create if and if/else 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
Declare and use an ArrayList
Using LoopConstructs
Create and use whileloops
Create and use for loops including the enhanced for loop
Create and use do/while loops
Compare loopconstructs
Use break and continue
Working with Methods and Encapsulation
Create methods with arguments and return values
Apply the static keyword to methods and fields
Create an overloadedmethod
Differentiate between default and user defined constructors
Create and overloadconstructors
Applyaccessmodifiers
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
Implementinheritance
Develop code that demonstrates the use of polymorphism
Differentiate between the type of a reference and the type of an object
Determinewhen casting isnecessary
Use super and this to access objects and constructors
Use abstractclasses and interfaces
Interface Example in Java 8
Handling Exceptions
Differentiate among checked exceptions, RuntimeExceptions and Errors
Create a try-catch block and determine how exceptions alter normal program flow
Describe what Exceptions are used for in Java
Invoke a method that throws an exception
Recognize common exception classes and categories
