Final Git Thoughts

  • .gitignore
  • .git/
  • Its complicated!

Programming Languages?

slide-26
SLIDE 26

Object Oriented Experience?

slide-27
SLIDE 27

Java Experience?

slide-28
SLIDE 28

Java Basics

  • Originally Oak, Java in 1995
  • Commercial language
  • Crazy popular
  • “Boring” reputation
slide-29
SLIDE 29

Java Highlights

  • Memory managed
  • Object oriented
  • JVM / Runtime
  • Fast (in some ways)
slide-30
SLIDE 30

Java Highlights

  • Bytecode
  • Packages / namespaces
  • Type safe
  • Rich ecosystem
  • Compiler improvements (unboxing, <>, etc.)
slide-31
SLIDE 31

Java Lowlights

  • Verbose


Integer coolInteger = new Integer(8);
 
 List<String> greatStrings = new List<String>();
 greatStrings.add(“Hachi Machi”);
 
 Packages

  • Heavy Tooling


IDEs, refactoring

slide-32
SLIDE 32

Java Lowlights

  • Fragile, Deep Type Hierarchies


Taxonomies are difficult, reworking them is tricky
 
 JSONReader, YAMLReader, SocketReader?

  • Industry / Enterprise Focus


XML, less open source uptake (especially earlier)
 
 Package management…

slide-33
SLIDE 33

Java Lowlights

  • Creaky in Points


Primitives vs. Arrays vs. Objects
 


int[] = {1, 2, 3};
 ArrayList<Integer> aList = new ArrayList<Integer>();
 aList.add(new Integer(4));
 aList.add(new Integer(5));

  • Redundant


So many ways to do the same thing…

slide-34
SLIDE 34

Java Lowlights

  • NULL


“billion-dollar mistake”
 
 String radString = null;
 if (radString != null) {
 radString.stringThing();
 }

  • Oppressive Type System


Glue classes, functional programming, etc

Using Java

Figure 1-1. How Java code is compiled and loaded

slide-36
SLIDE 36

Java Hello World

  • Boiler Plate and `main`
  • Primitive types
  • Control flow
  • Comments
  • References
  • Calling methods
  • Types
  • Building
  • Running
