Java中級類

INTERMEDIATE JAVA : This class teaches the intermediate level of the Java programming language. 

**********************************************************************
If your learner has never coded in Java, this is not the right 
class for them to join. If so, please join Introduction to Java instead.
**********************************************************************

Learners for intermediate Java are expected to be familiar with introductory concepts of Java already: language and syntax basics, building their own class, String, int, double, boolean, basic for loops, one dimensional arrays. These are covered in the Introduction to Java Class. 

In intermediate Java, we learn many medium level topics in Java such as handling errors and exceptions, building enums and constants.

We also build over our knowledge of class inheritance to understand interfaces and abstract classes and learn new keywords such as super, finally and final. We cover access modifiers and learn about  memory usage of variables in greater depth. 
And we also learn some medium level algorithms.

Topics covered:

Week 1: Error checks, types of exceptions, exception handling, finally and final
Week 2: Abstract classes and interfaces, use of super keyword
Week 3: Java enums, constants, object equality
Week 4: Access modifiers: public private protected
Week 5: Medium level algorithms: reverse a string, nested loops, odd and even number sums, multi dimensional arrays
Week 6: Memory usage of various data types, garbage collection, finalize method, complexity of algorithm (Big O)


In each class we will start with learning something new and then learners will be asked to do a small exercise to make the concept really sink in.

HOMEWORK:
----------------
Every class with end with weekly homework (less than an hour). Slides are posted to the classroom. While homework is not strongly enforced it is highly encouraged to help retain the material and really understand it.

TOOLS WE USE (ONLY BROWSER):
-------------------------------------
Learners will use an online programming site called onecompiler.com to type and test their code. This helps us focus on the class material and not the IDE. If learners already have a Java IDE(IntelliJ or Eclipse) installed and can get help using it, they may use that instead too. IDE is totally optional. The class will only use onecompile.com throughout.

We will learn concepts using a mix of code as well as slides. Both will be available to learners during the class.

If learners miss a class. they should watch the recording and do the examples taught before their next class.
