| Introduction to Object Oriented Programming concepts | Principles of Object Oriented Programming |
| Difference between Procedure Oriented and Object oriented | |
| Introduction to JAVA | |
| Types of java programs | |
| Applets and Applications | |
| Java Compilation process | |
| Java Source code | |
| Byte code | |
| Object code | |
| Java Virtual Machine (JVM) | |
| Features of JAVA | |
| Definition of Java applet and Java applications with examples | |
| Steps involved in compilation process | |
| Definitions of source code | |
| Byte code | |
| Object code | |
| Elementary Concept of Objects and Classes | Modelling entities and their behaviour by objects |
| A class as a specification for objects and as an object factory | |
| Computation as message passing/method calls between objects | |
| Objects encapsulate state (attributes) and have behaviour (methods) | |
| Class as a user defined data type | |
| Values and data types | Character set |
| ASCII code | |
| Unicode | |
| Escape sequences | |
| Tokens | |
| Constants and Variables | |
| Data types | |
| Type conversions | |
| Escape sequences [\n, \t, \\, \”, \’] | |
| Tokens and its types | |
| Primitive types and non-primitive types | |
| Introduce the primitive types with size in bits and bytes | |
| Implicit type conversion and Explicit type conversion | |
| Operators in Java | Forms of operators |
| Types of operators | |
| Counters, Accumulators | |
| Hierarchy of operators | |
| ‘new’ operator, dot ( . ) operator | |
| Forms of operators | |
| Types of operators | |
| Precedence and associativity of operators | |
| Prefix and postfix | |
| Creation of dynamic memory by using new operator | |
| Invoking members System.out.println() and System.out.print() for simple output | |
| Input in Java | Initialization |
| Parameters | |
| Introduction to packages | |
| Input streams (Scanner Class) | |
| Types of errors | |
| Types of comments | |
| Initialization – Data before execution | |
| Parameters – at the time of execution | |
| Input stream – data entry during execution – using methods of Scanner class | |
| Different types of errors occurring during execution and compilation of the program | |
| Single line comment (//) and multiline comment (/* … */ ) | |
| Mathematical Library Methods | Introduction to package java.lang |
| Methods of Math class | |
| Java expressions - using all the operators and methods of Math class | |
| Conditional constructs in Java | Application of if, if else, if else if ladder, switch-case, default, break |
| Fall through condition in switch case | |
| Menu driven programs, System.exit(0) - to terminate the program | |
| Iterative constructs in Java | Definition |
| Types of looping statements | |
| Entry controlled loops [for, while], exit controlled loop [do while] | |
| Variations in looping statements | |
| Jump statements | |
| Syntax of entry and exit controlled loops | |
| Break and continue | |
| Simple programs illustrating all three loops | |
| Inter conversion from for – while – do while | |
| Finite and infinite, delay, multiple counter variables | |
| Demonstrate break and continue statements with the help of loops | |
| Loops are fundamental to computation and their need should be shown by examples | |
| Nested for loops | Introduce nested loops through some simple examples |
| Demonstrate break and continue statements with the help of nested loops | |
| Programs based on nested loops | |
| Series involving single variables | |
| Computing and Ethics | Ethical Issues in Computing |

| Data protection on the internet | |
| Protection against spam | |
| Software piracy | |
| Cybercrime | |
| Hacking | |
| Protection against malicious intent and malicious code | |
| The stress on good etiquette and ethical practices |
