JAVA PRIMER
Getting Started
Pointers (C++):
Basic concept of pointer
Stack & Heap Memory Area
Address Mechanism
Dynamic Memory Allocation
new keyword (int *p = new int, int *p = new int(3), int *p = new int[3])
Object Creation using ‘new’ keyword
Tokens:
Character Set, Identifier, Variable, Literals, Keywords

Java is highly typed language, Type conversion & Casting
Operators:
Arithmetic, Relational, Logical, Unary, Conditional/Ternary, Assignment, Bitwise
