Page:

EXP54-J. Understand the differences between bitwise and logical operators
Page:

FIO53-J. Use the serialization methods writeUnshared() and readUnshared() with care
Page:

IDS55-J. Understand how escape characters are interpreted when strings are loaded
Page:

MET51-J. Do not use overloaded methods to differentiate between runtime types
