J2SE Course Details

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

Data-Type:

Java is highly typed language, Type conversion & Casting

Operators:

Arithmetic, Relational, Logical, Unary, Conditional/Ternary, Assignment, Bitwise

Control Statements:

Condition (if, if-else), Loops (while, do-while, for) & Branching (switch-case);

Introducing Classes & Objects:

What is Class?

What is Object?

Members: Data & Method

Access: Default, private, public, protected

Creating Class

Object Instantiation Process

What happen when object assign to other object or object compare with other object?

Array Instantiation

Command Line Argument

Constructor: Default, Parameterized

this Vs this()

Call by value & Call by reference

Passing Object as an argument (Adding two objects)

static data member, static method & static block

Inheritance:

Basics

Constructor calling sequence

Method Overloading Vs Overloading with example

Super class variable can reference a subclass object

abstract method & abstract class

Runtime Polymorphism

final method & final class

abstract Vs final

abstract Vs Interface

Object class: equal, toString, finalize method etc.

Object Life Cycle

Managing Packages:

Basics

Setting classpath

Standard packages

Arrays & String;

Exception Handling:

Java I/O:

Streams

Byte & Character

Sink & Processing

String concatenation

Serialization, Transient etc.;

Be familiar with java.net package & Socket Programming:

java.lang & java.util Packages:

Collection API: Add, Remove & Iterate Objects; Type Wrapper: Importance of Wrapper Classes, String to Native Type Conversion;

Working with Java IDE (NetBeans/Eclipse/J-Builder etc):

Presentation Instructions

1. Precisely explain concept with example.
2. Whenever needed present Figures & Diagram.
3. Presentation should be prepared on PowerPoint.
