What we cover in our course?

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 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; 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

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
