C/C++ vs Java - differences
For C/C++ Java
Constants Header file Interfaces or
static/final fields
Referencing
other code
#include import
Primitives bool, int, short, etc boolean, short, int,
long, float, double
Strings char[] or string String
These are not logical equivalents. Just in similar spaces.

14.
Same in Java
Lots
Arrays
If statements
Math
Calling a method (mostly)
Comments

15.
Big differences in Java
Garbage collection!
no malloc/free – unless calling C/C++
No pre-processor directives
No pointers
No operator overloading
Platform independent

16.
Android Studio - Views
Default – Android view
Project view – shows file system

17.
Android Studio – Autocomplete
Control + space

Blame marketing!
What books are good for learning Java?
Head First Java
Thinking in Java (older versions free)
Java for Dummies
Deitel & Deitel
Core Java
